10
Welcome!
System Specifications lists technical details about your system. The Handy Cheat Sheet gives a short summary of some of the most needed or most forgotten commands. The Glossary gives definitions of common computer terms.

Chapter 1 - Unpacking Your System
1. Unpacking Your System
Obviously, the first step towards using your new Meridian is getting it safely to your door and unpacked.
Do I Have Everything?
The packing slip is one of the last items sealed into your computer box. It lists everything we shipped you. As you unpack the box, check the contents against the packing slip. If an item is listed on your packing slip, but isn't in the box, it may be installed in your system, or shipped inside one of the manuals or accessory bags. If you're sure something is missing, call Customer Service right away. The Customer Service phone number is listed on an insert to this book.
12
Chapter 1 - Unpacking Your System
What's in the Box?
Your box contains the packing slip, this manual, a plastic bag full of cables and other manuals, a battery pack and AC adapter, and your Windows & DOS manual. This book shows you how to set up your system and keep it running. Your Windows for Workgroups & MS-DOS User's Guide has introductory chapters to help you install and configure DOS and Windows. Since we have already loaded and tested DOS and Windows on your hard drive, you can probably skip those parts for now. Those chapters will be useful if you ever have to start over on your own and reinstall DOS or Windows onto your computer. For now, this book should get you up and running.
13
Chapter 1 - Unpacking Your System
Let Your Computer Acclimate Itself
Although your computer system can easily stand temperature extremes, it doesn't much like rapid changes in temperature, especially going from a cold front stoop to a warm and comfy office, or from a steamy jungle mail drop to an air-conditioned villa. Rapid changes in temperature can cause condensation inside your case. If it is hot or cold outside when you receive your system, let the computer gradually adjust to room temperature before you plug it in. When you first receive your computer you will certainly be eager to get it going and start putting it to work, but be patient. Take the time to let it grow accustomed to its new environment.
Keep the Box
It's a good idea to keep your Meridian's box and packing materials. That way, if you ever have to store the system or return it, your components will be well-protected.
14
Chapter 1 - Unpacking Your System
Where to Work
Your Meridian 800 is a tough, rugged machine. Generally speaking it will be comfortable and run well wherever you are comfortable. Extremes of heat, cold, and humidity can be challenging to your system's parts, but usually if you can take it, so can the computer. There are, however, some things you take very easily that the computer does not like at all. Static electricity is one. Dust, water, steam, and oil are others. Wherever you decide to pull over for roadside computing, choose a clean, comfortable work area for your system.
Note: It's best to place your Meridian near a wall socket for easier access.
Beware Heat, Cold, Humidity, and Glare
Pick a spot for your computer that's not too - not too hot and not too cold, not too dark and not too bright - glare can make it hard to read the screen. Overheating can destroy computer components. Allow plenty of room for air to circulate around the system unit. Also, be sure to use grounded electrical outlets. Although your computer has its own electrical filters, fuses, and protections, and even its own builtin surge suppressor, we strongly recommend using an external surge suppressor to ensure your system is safe. An external surge suppressor looks like an extension cord with several grounded outlets. High quality surge protectors shield your computer from lightning strikes, surges, shorts, and other electrical hazards.

Using the Keyboard
Function keys Escape Backspace
Tab
Alt Fn key Ctrl Shift Enter
The keyboard is your primary means of telling the computer what to do and giving it the numbers and words to do it. The keyboard works much like the keys on a typewriter, but computer keyboards have several specialty keys. Over time, most software packages have settled on some standard uses for the specialty keys. For example, in most software packages, pressing the F1 key gets help. The chart on the next page explains the most important keys on the keyboard.
25
Chapter 2 - The Big Picture
What the Keys Do
General Functions Alternate (Alt) - used with other keys to perform special functions defined by the application you are using. While holding down the Alt key, press the other key. Caps Lock - toggles on and off making the typewriter letter keys appear in uppercase. Control (Ctrl) - used with other keys to perform special functions defined by the application you are using. While holding down the Ctrl key, press the other key. Delete (Del) - deletes the character to the right of the insertion point. Enter - tells the computer you're done typing and want it to execute your command. Some people call this the Return key. Also used as a paragraph return key when typing. Escape (Esc) - generally allows you to escape a function without completing it. Function Keys (F1 through F12) - the purpose of the function keys depends on the application you are using. Insert (Ins) - toggles between insert and overtype mode. In insert mode, whatever you type pushes any existing characters to the right, "downstream." In overtype mode, new characters simply overwrite existing characters, deleting them as you go. Pause - typically suspends the application you are using. Not all applications use the Pause key. Print Screen - typically prints out the current screen on the printer. Sometimes used with the Ctrl key. Some applications disable this function or require special drivers to work properly with this key. Scroll Lock - defined by the application software you are using. Not all applications use the Scroll Lock key. Shift - shifts the typewriter keys from lower to upper case or from the lower symbol to the upper symbol on the key.
26
Chapter 2 - The Big Picture
What the Keys Do (continued)
Editing and Movement Keys Backspace (Bksp) - located above the Enter key. It may be labeled as Bksp or as an arrow pointing to the left. The Backspace key moves the insertion point to the left one space, erasing the characters in its path. Down Arrow - moves the insertion point down one line. End - moves the insertion point to the end of the line or screen. Home - moves the insertion point to the top left side of the current page or screen. Left Arrow - moves the insertion point to the left one space. Page Down (PgDn) - scrolls the screen page down to the next page. Page Up (PgUp) - scrolls the screen page up to the previous page. Right Arrow - moves the insertion point to the right one space. Tab - moves the insertion point to the next tab setting or field. Typically, Shift+ Tab moves the insertion point back one tab setting or field. Up Arrow - moves the insertion point up one line. Num Lock (Number Lock) - toggles the numeric keypad. When the Num Lock light is on, the keys on the right side of the keyboard work like a ten-key calculator. When the Num Lock light is out, the keys move the insertion point. Special Key Combinations Ctrl + Alt + Del - restarts the computer. Also called a "warm boot" because it clears the memory, resets, and reboots the computer without stopping the hard drive. This will not save your current work. Ctrl + Alt + S - Run SETUP program. Ctrl + Alt + P - Run Power management program, or view remaining battery life. Ctrl + Break or Ctrl + C - Break out of the current program.
27
Chapter 2 - The Big Picture
Using the Embedded Numeric Keypad
A numeric keypad for entering numbers is embedded within the main keyboard. To use the numeric characters, press the Num Lock button. Keys with a number in the lower right corner will type numbers whenever Num Lock is enabled. To return the keys to normal letters, press Num Lock again. If you install an external keyboard or keypad, the keypad function is disabled.

Chapter 2 - The Big Picture
Special Key Combinations
The following key combinations let you perform special functions without exiting your application
Note: Some applications may conflict with certain special key combinations. If you press key combination without results, exit the application and try again.
Fn + F10 Fn + F11 Fn + F12
Decreases LCD display contrast Increases LCD display contrast Sets beep volume
Setting the Speaker Volume
Pushing FN + F12 cycles through the four volume levels for the internal speaker. When you set the volume level, the system records and remembers the level you set for the Power On beep, the Suspend Mode beep, and the normal system beep. This setting is retained in memory even when you turn the system off. Low battery alerts, however, always reset to the maximum volume when you boot the system. To lower the volume of the low battery alert, cycle through the volume settings by pressing Fn + F12.
Note: Some settings such as BIOS errors and unknown system problems will always beep at maximum volume.

Chapter 3 - Battery and Power Management
Turning On Your System
After installing the battery pack, allow it to charge fully before using your system for the first time. Once the battery is fully charged, go ahead and open your system and push the power button. Hold the button down for one second to turn on the system.
Note: Be sure to wait at least one to two seconds between each time you press the power button. Otherwise, the button may not respond.
Battery Endurance
How long you can run on a single charge varies greatly with how you use and configure your system. Your Meridian can run a lot longer if you do one or more of the following: · Use the AC adapter whenever possible · Operate the system at "Slow" clock speed · Operate in cooler temperatures · Set the LCD brightness to "Half" level in the SETUP program · Store the battery in low humidity
See Chapter 5, Using SETUP, to learn how to set the power management features.
36
Chapter 3 - Battery and Power Management
Low Battery Conditions
Two warnings alert you when your system's battery is low and needs charging. The first warning is the orange battery indicator light blinking slowly. The system speaker will also beep. The first warning occurs about eight minutes before the second one. At the first warning, you should quit working and save your data, or connect the AC adapter to the system immediately. Otherwise, your data may be lost. At the second warning the orange battery indicator light blinks rapidly and the system speaker beeps again. After the second warning, the system could shut down at any moment, erasing all your unsaved work. Warning!
Systems containing more than the base amount of system memory might have a slightly shorter initial low-battery warning. Note: Even if your low battery warning volumes are set to OFF, the system speaker will beep to alert you to a low battery problem.
If you receive a low battery warning, you should immediately do the following: If your AC adapter and a power outlet are available:
1. Set in suspend mode by pushing the suspend/resume button. 2. Connect the AC adapter to the system. 3. Resume the system from suspend mode by pushing the suspend/resume button.
Continued next page

Chapter 3 - Battery and Power Management
Low Battery Conditions (continued) If an extra fully charged battery is available:
1. Save all necessary files. 2. Exit the application. 3. Turn off the system. 4. Remove the battery pack and replace it with a fully charged battery pack.
If no AC adapter, power outlet or extra charged battery is available:
1. Save all necessary files. 2. Exit the application. 3. Turn off the system.
38
Chapter 3 - Battery and Power Management
Charging the Battery
To charge the battery, plug the AC adapter into the system and an electrical outlet. The AC adapter converts alternating current (AC) into direct current (DC). When the power switch is turned on, the AC adapter supplies power to the system and recharges the battery pack only when the system in suspend mode. Otherwise, to recharge you must turn off the computer. Recharging takes about 80 minutes for an empty battery pack when the computer is off or in suspend mode. The battery will not recharge while the computer is being used. While the battery is charging, the CHARGE LED is orange. Once the battery is fully charged, the CHARGE LED turns green.
Pre-charging a Dead Battery
If the battery has been completely discharged or placed in prolonged storage, it may need a pre-charge in addition to a normal charge. A pre-charge can take as little as a few seconds or as much as an hour in some extreme cases. While the battery pre-charges, the CHARGE LED will slowly flash orange.
Battery Temperature Sensor
The AC adapter will not charge a battery when it is too hot or too cold. If the battery is outside normal operating temperature, the adapter will wait for the battery to warm up or cool down before it begins charging. While the system unit waits for the battery to return to normal operating temperature, the CHARGE LED will slowly flash green.

Faulty Battery Indicator
The orange CHARGE LED may flash when a faulty battery pack is installed. If the CHARGE LED flashes orange rapidly, remove the faulty battery pack immediately.
Warning!
Powering the system with the AC adapter and a faulty battery pack installed can damage the AC adapter.
Don't Unplug the AC Adapter with the Power On
Never unplug the AC adapter when the system is turned on. This may cause your computer to behave unpredictably. However, you don't need to turn off the computer before connecting the AC adapter, if the adapter is plugged into an outlet.

Chapter 3 - Battery and Power Management
Setting Power Management
Your system can operate in one of three power modes: normal, power saving, or suspend.
Normal Mode
The system runs at the speed specified in SETUP (Full, Slow).
Power Saving Mode
Power saving mode reduces power to the hard drive after several minutes of inactivity. You can set the amount of time the system should wait before powering down the hard drive. If no activity is detected during the period of time specified in SETUP, the system switches to the power saving mode. See Chapter 5, Using SETUP, for more information about setting the power saving configuration.
Suspend Mode
In suspend mode, system clock speed is lowered to 0 MHz and the green power/suspend light blinks continuously. Push and hold the suspend/resume button for about one second to enter or cancel suspend mode.
Warning!
While in Suspend Mode, the system still draws a small amount of power. If you leave your system in Suspend mode for a long time, the battery will eventually run down.

Battery Precautions
1. Do not expose the battery to fire, which can cause explosion, or allow it to become dented or deformed. 2. Do not run your system on battery power for a long time at temperatures over 95 degrees F (35C). Also, do not store the battery at high temperatures. This can significantly reduce battery life. 3. Temperature extremes can greatly affect the life of the battery. It should be kept in a low-humidity area and temperature range of between 14 and 104 F (-10 and 40 C) when being stored for less than one month and between 14 and 86 F (-10 and 30 C) when being stored for over one month. 4. The battery may be damaged if it is used in any device other than your computer. Also, do not attempt to use your computer with any other make of AC adapter or battery charger. This includes the Meridian 400 AC adapter. 5. Do not force the battery into the system unit. Do not drop it. 6. Do not short-circuit the battery electrodes. 7. Do not be alarmed if the battery feels warm to the touch when installed in your system. This is normal. 8. If the CHARGE LED on the computer blinks green while charging, remove the battery pack and allow it to return to normal operation temperature before recharging. 9. After recharging, if the battery power quickly becomes weak, or if the CHARGE LED on the computer blinks orange rapidly during recharging, the battery power pack's service life has probably come to an end. Promptly replace it with a new battery pack, or remove the battery pack and use AC adapter for power source. Do not leave a dead battery pack in the computer. 10. Do not to open the pack. It contains harmful materials that can catch fire when exposed to the air or chemically burn your skin. Dispose of batteries according to local regulations. 11. The battery may not charge if its contacts become dirty. You can clean the contacts with a cloth.

AC Adapter Precautions
1. It is extremely dangerous to use the AC adapter when it is wet. If it should become wet or damaged, immediately unplug the adapter from the power outlet and the computer. 2. Do not subject the adapter to strong vibration or shocks. Be careful not to drop it. 3. Do not expose the adapter to direct sunlight for prolonged periods. 4. Do not use or store the adapter near chemicals or around corrosive gases. 5. Do not use or store the adapter in places subject to extreme temperatures or near a heat-producing source. Avoid using it in extreme humidity or dusty conditions. 6. Do not unplug the AC power cord or DC connector by pulling on the cord. Instead, grasp the plug firmly and pull it out. Also, do not hold the adapter by its AC cord or DC input connector. 7. After unplugging the DC input connector from the computer or AC power cord from the adapter, wait at least 5 seconds before attempting to reconnect it. 8. Do not attempt to open the adapter, which has no user-serviceable parts. Opening it can result in electrical shock or adapter malfunction. 9. When the adapter is not being used, unplug its AC power cord. While attached to a wall outlet, the adapter continues to supply DC voltage to the plug connector even when it is unplugged from the computer. If the loose plug comes into contact with metal, a short circuit could occur, causing damage to the adapter. 10. Do not use the adapter with any other devices other than this computer. This includes the Meridian 400. Also, do not attach any other make of AC adapter other than the one supplied with the computer. Even momentarily attempting to use a different adapter can cause serious or fatal damage to your computer. 11. To ensure proper ventilation and heat dissipation, keep the AC adapter positioned with its top upward. Also, do not cover the adapter during use with cloth, paper or other materials that can interfere with heat release, or it may become damaged.

TruePointTM Pointing Device
The red button, called the TruePointTM embedded pointing device, works like a joystick. Simply put a finger on it and tilt it the direction you want the cursor on the screen to go. The harder you tilt, the faster it moves. When you need to click on something, use the rectangular mouse buttons (on top of the wrist rest) exactly as you would use the two buttons on a mouse.
Note: If the cursor moves too quickly for you, change its sensitivity. In Windows, select the mouse icon from the Control Panel and click on Sensitivity. In DOS, run the MOUSE program with the /S flag. See your Windows & MS-DOS User's Guide for more details.

PS/2 Style Mouse
Before you can use an external mouse, you must first install its device driver. This software enables your mouse to communicate with the system. See your mouse documentation for instructions how to install the mouse and mouse driver. Your system automatically switches to a PS/2 mouse if one is connected to the PS/2 Mouse port. You cannot use both the embedded pointing device and the external mouse at the same time.
Note: A PS/2 style mouse may not work correctly if you connect it after bootup. Always turn the power off before connecting a PS/2 style mouse.
Serial Mouse
Before you can use any external mouse, you must first install its device driver. This software enables your mouse to communicate with the system. See your mouse documentation to learn how to install the mouse and mouse driver.
To use a serial mouse, first disable the TruePoint pointing device in SETUP. On the SETUP menu (Ctrl-Alt-S at the DOS prompt) Set Pointing Device to "Disabled." After the TruePoint device is disabled, connect a serial mouse to the serial port at the back of the system unit. Do not try to connect a PS/2 style mouse to the serial port. The mouse will use the COM1 serial port.

External Video Monitor
Your Meridian 800 comes with DOS and Windows utility programs for switching from the LCD display to an external monitor. By default, the computer will reroute its video signal to an external monitor if it is attached on power up. However, if you hook up an external monitor during use, the LCD screen still works. If you use the Meridian with the LCD panel closed, you must run the system with the AC adapter plugged in. If the LCD panel is open, you can view both screens at the same time with no added drain on the battery.
External Keyboard
Connect a normal 101-key keyboard with a suitable adapter, then turn on power. The external keyboard will operate in conjunction with Meridian's onboard keyboard.

Floppy Disks
Floppy disks are used to: · transfer information from one computer to another · install software on your system's hard drive · make backup copies of your software and data
When you insert a floppy disk into the system's floppy disk drive, you can read the information stored on the disk and write information to the disk. Your Meridian 800 comes with a 3.5-inch 1.44MB internal floppy drive. You can use either high-density (1.44MB storage capacity) or double-sided/double-density (720KB storage capacity) floppy disks in this drive. You can tell the disks apart by looking at the edge of the disk opposite the sliding metal panel.
· 1.44MB disks have a write-protected tab on one side and a sensing hole on the other side · 720KB disks have only a write-protect tab
To write-protect either kind of disk, slide the plastic writeprotect tab towards the edge, uncovering the hole. As you push the disk into the drive you will hear a faint click as the disk slides into place. To release the disk, push the button on the upper right side of the disk opening.
