About Barometric and Temperature Measurements Barometric Pressure Graph Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. This watch takes barometric pressure measurements automatically every two hours (at the top of each even-numbered hour), regardless of its current mode. Measurement results are used to produce barometric pressure graph and barometric pressure differential pointer readings. The barometric pressure graph shows readings of previous measurements for up to 30 hours. The horizontal axis of the graph represents time, with each dot standing for two hours. The rightmost dot (flashing) represents the most recent reading. The vertical axis of the graph represents barometric pressure, with each dot standing for the relative difference between its reading and that of the dots next to it. Each dot represents 1hPa. The following shows how to interpret the data that appears on the barometric pressure graph. A rising graph generally means improving weather. A falling graph generally means deteriorating weather. Note that if there are sudden changes in weather or temperature, the graph line of past measurements may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize. Not visible on The following conditions cause the barometric pressure measurement to be skipped, with the corresponding point on the display. the barometric pressure graph being left blank. · Barometric reading that is out of range (260 hPa/mb to 1,100 hPa/mb or 7.65 inHg to 32.45 inHg) · Sensor malfunction · Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, barometric pressure and temperature measurements are taken every five seconds. · The ACT indicator flashes on the display while a measurement is in progress. · You can also perform a barometric pressure and temperature measurement at any time by pressing B in the Barometer/Thermometer Mode. Altimeter The watch's altimeter uses a pressure sensor to detect current air pressure, which is then used to estimate the current altitude based on ISA (International Standard Atmosphere) preset values. You can also specify a reference altitude, which the watch will use to calculate your current altitude based on the value you specify. Altimeter functions also include storage of measurement data in memory and an altitude alarm. Important! · This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air pressure changes. · The semiconductor pressure sensor used by the watch for altitude measurements is also affected by temperature. When taking altitude measurements, make sure the watch is not subjected to temperature changes. · To avoid the effect of sudden temperature changes during measurement, keep the watch on your wrist in direct contact with your skin. · Do not rely upon this watch for altitude measurements or perform button operations while sky diving, hang gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in any other activity where there is the chance of sudden altitude changes. · Do not use this watch for measuring altitude in applications that demand professional or industrial level precision. · Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings produced by this watch will not match the altitude readings announced or indicated the flight crew. Barometric Pressure Differential Pointer This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph, and the current barometric pressure value displayed in the Barometer/ Thermometer Mode · Pressure differential is indicated in the range of ±15 hPa, in 1-hPa units. · The barometric pressure differential pointer is not displayed when the displayed current barometric value is outside of the allowable measurement range (260 to 1,100 hPa). · Barometric pressure is calculated and displayed using hPa as the standard. The barometric pressure differential can also be read in inHg units as shown in the illustration. Current pressure greater than most recent measured pressure How the Altimeter Measures Altitude The altimeter can measure altitude based on its own preset values, or a reference altitude specified by you. When you measure altitude based on preset values Data produced by the watch's barometric pressure sensor is converted to approximate altitude based on ISA (International Standard Atmosphere) conversion values stored in watch memory. When you measure altitude using a reference altitude specified by you After you specify a reference altitude, the watch uses that value to convert the current measured barometric pressure value to altitude. · To determine the height of a tall building, for example, specify zero for the reference altitude value while you are on the ground floor. Then when you go to a higher floor, the altitude displayed by the watch will indicate the height from the ground floor. Note that you may not be able to get a good reading if the building is pressurized or air-conditioned. · When mountain climbing, you can set the B reference value in accordance with a marker along the way or altitude information from a A map. After that, the altitude readings 400 produced by the watch will be more accurate than they would without a reference altitude. inHg values Barometric pressure differential pointer hPa values Points to 9 o'clock for differentials outside the range of ±15 hPa/ ±0.44 inHg. Pressure differential examples in the illustration are indicated in 10 hPa/0.3 inHg steps. Current pressure less than most recent measured pressure Displaying Your Current Altitude You can use the procedure described in this section to display your current altitude. If you leave the watch in the Altimeter Mode, it will regularly update the displayed altitude value, and indicate reading-to-reading changes in the altitude graph at the top of the display. Important! · The procedure in this section simply displays values indicating your current altitude, without storing them in watch memory. For information about recording altitude readings in watch memory, see "Saving Altitude Data". To turn display of the barometric pressure differential pointer on and off 1.

The watch's auto light switch automatically turns on illumination when you angle the watch towards your face. · The auto light switch must be turned on (indicated by the auto light switch on indicator) for it to operate. · You can specify 1.5 seconds or 2.5 seconds as the illumination duration. · See "Illumination Precautions" for other important information about using illumination. To turn on illumination manually Press L in any mode to illuminate the display. · The above operation turns on illumination regardless of the current auto light switch setting. · Illumination is disabled while the Digital Compass, Barometer/ Thermometer, or Altimeter Mode setting screen is on the display. 7 Operation Guide 2894 About the Auto Light Switch Turning on the auto light switch causes illumination to turn on, whenever you position your wrist as described below in any mode. Note that this watch features a "Full Auto EL Light", so the auto light switch operates only when available light is below a certain level. It does not illuminate the display under bright light. Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on. · Wear the watch on the outside of your wrist. Parallel to ground Question: How does the barometer work? Answer: Barometric pressure indicates changes in the atmosphere, and by monitoring these changes you can predict the weather with reasonable accuracy. Rising atmospheric pressure indicates good weather, while falling pressure indicates deteriorating weather conditions. The barometric pressures that you see in the newspaper and on the TV weather report are measurements corrected to values measured at 0 m sea level. Question: How does the altimeter work? Answer: Generally, air pressure and temperature decrease as altitude increases. This watch bases its altitude measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO). These values define relationships between altitude, air pressure, and temperature. Altitude Air Pressure 616 hPa 3500 m 3000 m 2500 m 2000 m 1500 m 1000 m 0m 500 m 701 hPa 795 hPa 899 hPa 1013 hPa About 8 hPa per 100 m About 9 hPa per 100 m About 10 hPa per 100 m About 11 hPa per 100 m About 12 hPa per 100 m More than 40° Temperature ­11°C ­4.5°C 2°C 8.5°C 15°C About 6.5°C per 1000 m Warning! · Always make sure you are in a safe place whenever you are reading the display of the watch using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you. · When you are wearing the watch, make sure that its auto light switch is turned off before riding on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury. 4000 m To turn the auto light switch on and off In any mode except while a setting is flashing on the display, hold down L for about three seconds to toggle the auto light switch on (A.EL displayed) and off (A.EL not displayed). · The auto light switch on indicator (A.EL) is on the display in all modes while the auto light switch is turned on. · The auto light switch turns off automatically whenever battery power drops to Level 4. · Illumination may not turn on right away if you raise the watch to your face while a barometric pressure or altitude measurement operation is in progress. · The auto light switch is always disabled, regardless of its on/off setting, when any one of the following conditions exists.

Absolute altitude expresses an absolute height above sea level. Relative altitude expresses the difference between the height of two different places. To specify the illumination duration 1. In the Timekeeping Mode, hold down E until the city code starts to flash, which indicates the setting screen. 2. Press D three times to move the flashing to the seconds setting. 3. Press A to toggle the illumination duration setting between 2.5 seconds ( ) and 1.5 seconds ( ). 4. After the setting is the way you want, press E to exit the setting screen. Height of building 130 m (relative altitude) Rooftop at an altitude of 230 m above sea level (absolute altitude) lll lll ll Sea Level Precautions Concerning Simultaneous Measurement of Altitude and Temperature Though you can perform altitude and temperature measurements at the same time, you should remember that each of these measurements requires different conditions for best results. With temperature measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat. In the case of altitude measurement, on the other hand, it is better to leave the watch on your wrist, because doing so keeps the watch at a constant temperature, which contributes to more accurate altitude measurements. The following describes what you should do to give priority to either altitude or temperature. · To give altitude measurement priority, leave the watch on your wrist or in any other location where the temperature of the watch is kept constant. · To give temperature measurement priority, remove the watch from your wrist and allow it to hang freely from your bag or in another location where it is not exposed to direct sunlight. Note that removing the watch from your wrist can momentarily affect pressure sensor readings. lll Questions & Answers Question: What causes incorrect direction readings? Answer: · Incorrect bidirectional calibration. Perform bidirectional calibration. · Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move away from large metal objects and try again. Note that digital compass operation cannot be performed inside a train, boat, etc. Question: What causes different direction readings to produce different results at the same location ? Answer: Magnetism generated by nearby high-tension wires is interfering with detection of terrestrial magnetism. Move away from the high-tension wires and try again. Question: Why am I having problems taking direction readings indoors ? Answer: A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism readings. Move away from the object causing the interference or take the direction reading outdoors. Indoor direction readings are particularly difficult inside ferro-concrete structures. Remember that you will not be able to take direction readings inside of trains, airplanes, etc. llll 8 Operation Guide 2894 Power Supply This watch is equipped with a solar cell and a special rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.

When this happens, ERR (error) will appear on the display and sensor operations will be disabled. Digital Compass Measurement Barometric Pressure Measurement Altitude Measurement · The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all modes. · The watch's built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except when battery power drops to Level 4. · The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on your Home City time setting. · GMT differential is calculated by this watch based on Universal Time Coordinated (UTC) data. Illumination Precautions · The electro-luminescent panel that provides illumination loses power after very long use. · Illumination may be hard to see when viewed under direct sunlight. · Illumination automatically turns off whenever an alarm sounds. · The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction. · Frequent use of illumination runs down the battery. · If ERR appears while a measurement operation is being performed in a sensor mode, restart the measurement. If ERR appears on the display again, it can mean there is something wrong with the sensor. · Even if battery power is at Level 1 or Level 2, the Digital Compass Mode, Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. In this case, ERR will appear on the display. This does not indicate malfunction, and sensor operation should resume once battery voltage returns to its normal level. · If ERR keeps appearing during measurement, it could mean there is a problem with the applicable sensor. Whenever you have a sensor malfunction, be sure to take the watch to your original dealer or nearest authorized CASIO distributor as soon as possible. Auto light switch precautions · Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display. · Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the battery. More than 15 degrees too high Power Saving When turned on, Power Saving automatically enters a sleep state whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving. · There are actually two sleep state levels: "display sleep" and "function sleep". · Illumination may not turn on if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground. · Illumination turns off after the preset illumination duration (see "To specify the illumination duration"), even if you keep the watch pointed towards your face. Elapsed Time in Dark 60 to 70 minutes (Display Sleep) 6 or 7 days (Function Sleep) Display Blank, with PS flashing Blank, with PS not flashing Operation Display is off, but all functions are enabled. All functions are disabled, but timekeeping is maintained. · Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state. · The watch will not enter the sleep state while the digital time is between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when the digital time reaches 6:00 AM, however, it will remain in the sleep state. · The watch will not enter the sleep state while it is in the Countdown Timer or Stopwatch Mode. · Static electricity or magnetic force can interfere with proper operation of the auto light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again. · Under certain conditions, illumination does not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction. · You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch. Digital Compass Precautions This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that north indicated by this watch is magnetic north, which is somewhat different from true polar north. The magnetic north pole is located in northern Canada, while the magnetic south pole is in southern Australia. Note that the difference between magnetic north and true north as measured with all magnetic compasses tends to be greater as one gets closer to either of the magnetic poles. You should also remember that some maps indicate true north (instead of magnetic north), and so you should make allowances when using such maps with this watch. Location · Taking a direction reading when you are near a source of strong magnetism can cause large errors in readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.) · Accurate direction readings are impossible while in a train, boat, air plane, etc. · Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures picks up magnetism from appliances, etc. Storage · The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of this, you should be sure to store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal computers, washing machines, freezers, etc.) · Whenever you suspect that the watch may have become magnetized, perform one of the calibration procedures under "Calibrating the Bearing Sensor". To recover from the sleep state Perform any one of the following operations. · Move the watch to a well-lit area. It can take up to two seconds for the display to turn on. · Press any button. · Angle the watch towards your face for readings. To turn Power Saving on and off 1.
