Designed to be durable, this unit is constructed for rugged outdoor use. The EB833 has three primary functions. 1. An Altimeter - Functions related to altitude measurement. 2. A Barometer and Weather Forecast Device - Functions related to weather forecasts and atmospheric pressure. 3. Clock, Current Date Calendar, and Count-Up Timer - Functions related to time, date, and time measurement. An altimeter, the EB833 will measure and display current altitude readings, changes between two elevations, and maximum and minimum altitudes. The unit stores altitude data and can indicate changes in altitude for a 12-hour period or calculates the total accumulation of elevation ascents over a given period of time. In addition, the user can set an altitude alarm that will activate when specified elevations are reached. The EB833 is also a barometer. It measures and displays current pressure readings, and provides a barometric history and a bar graph showing barometric changes over a 12-hour period. A weather forecast device, the EB833 uses barometric information to make forecasts as sunny, slightly cloudy, cloudy, and rainy. It also has a built-in thermometer. 2 As a timepiece, this unit functions as a clock / calendar, daily alarm, and count-up timer. To optimize the usefulness of this device, be sure to read this instruction manual carefully before use, and keep it handy for future reference.

During initial packaging, the batteries were insulated with a red tape so as to maximize the shelf life of the product. Before use, remove the insulation tape by gently pulling. Upon removal, the display will show a full-segment display for 3 seconds; it will then enter the Normal Altitude Display. FULL SEGMENT DISPLAY 3 GB GB Follow these steps to install or replace batteries: 1. Open battery cover located at the back of the unit by removing screws. 2. Insert 2 (two) new CR-2032 Lithium batteries. GENERAL OPERATION OF THE ALTIMETER In Altimeter Mode, by detecting changes in air pressure, the EB833 determines a given altitude level. Subsequently, the unit can be set to show changes in altitude and maximum / minimum elevations. It can store altitude-related data and display elevation trends over a 12-hour period of time. The unit can also display the net total of accumulative ascents. A small icon indicates that the unit is in Altimeter Mode and that the displays are altitude related. To view display sequences in Altimeter Mode: 1. Press [ALT] to move between various Altimeter Mode displays. Normal Altitude Display 3. Replace the battery cover. A battery-low indicate [ BATT ] will show on the display when the batteries require changing. It is recommended that when the user is stationary at one elevation, that the unit is placed in Barometer Mode. The Altimeter Mode may shorten battery life. Stored altitude related data is not affected by having the unit in Barometer Mode for extended periods of time. Note: Disposed of improperly, batteries can be harmful. Protect the environment by taking exhausted batteries to authorized disposal stations. 4 The first display in Altimeter Mode. Note: If the unit is being used for the first time, it will automatically enter the Normal Altimeter Display.

Press [+] or [-] to display previous altitude levels at one-hour intervals for the past 12-hours. 5. Press [ALT] again to view the Altitude Alarm Display. Display shows: Alarm display indicator Change in altitude Alarm On/Off Indicator Altitude level where the alarm will activate 3. Press [ALT] again, to view the Altitude Min Memory Display. Display shows: Minimum altitude reached Accumulative vertical decent icon Accumulative vertical decent memory Current Time ALTITUDE ALARM DISPLAY Current Temperature ALTITUDE MIN MEMORY DISPLAY 5 GB GB 6. Press [ALT] again, the unit will return to the Normal Altitude display. Note: The unit will return to Normal Altimeter Display if no buttons are pressed for one-minute during the calibration sequence. Altitude Calibration If the altitude on the display is different from the actual current altitude, the unit can be manually calibrated to reflect the true altitude level. To calibrate the altitude: 1. In Normal Altitude Display. 2. Press and hold [ALT] and [TIME] simultaneously for about 2 seconds. The CAL Hx indicator shows on the display and the current altitude digits start flashing. 3. Press [+] or [-] to adjust the altitude reading by 1 m. For rapid acceleration of measurement adjustments, press and hold. 4. Press [ALT] to confirm and return to the Altitude Display. Units of Measurement for Altitude Altitude measurements can be displayed in feet (ft) or meters (m). To change the altitude units of measure: 1. In Normal Altitude Display. 2. Simultaneously, press and hold the [+] and [-] to select between meters or feet. About The Altitude Change Graph In Normal Altitude Display, the EB833 graphically display altitude levels at 2-hour time intervals for the past 12 hours. Each vertical bar on the altitude graph represents a 2-hour time period. Each horizontal line represents pressure changes equal to + /200-meters. Example: Point C: A point where the altitude, as indicated by a marking stone or post, is 1500 m. At this point set the current altitude to 1500 m. 6 ( 2 hours per column ) The Altitude Change Graph is viewed in all the Altimeter Mode displays. Point A: At this point, reset the Altitude Change Memory to 0 m. / ft. The EB833 will immediately start recording new changes in altitude. Point B: At this point, check the Altitude Change Memory. The unit will display the net vertical difference between point A and point B. Altitude History Display In addition to having altitude information displayed as a graph, altitude history can also be displayed numerically. To numerically display previous altitude levels: 1. Enter the Altitude History Display 2. Press [+] or [-] to display the corresponding altitude history for a specified time period up to ­12 hours. Clearing Altitude Memory, Max / Min Altitude Memory, and Vertical Ascent / Decent Memory Altitude related memories are cleared sequentially. During the sequence, correct information can be bypassed by pressing [ALT]. Note: To clear the maximum altitude reached memory, first enter MAX Altitude Display. Alternately, enter MIN Altitude Display to clear the minimum altitude reached memory. To clear Altitude Mode Memories: 1. Enter Altitude Max (or Altitude Min) Display. 2. Press and hold [ALT] for about 2 seconds, the change-inaltitude digit flash. Note: To bypass any section without making changes to the memory, press [ALT]. 3. Press [+] or [-], the change-in-altitude digits will reset to 0 m./ft. 4. Press [ALT], and proceed to the maximum (or minimum) About Altitude Change Memory The EB833 can monitors the change in altitude between two points. The unit displays the net vertical difference between points of a descent / ascent. Upon clearing the altitude memory, the current altitude reading is used as a base from which the unit starts recording changes. 7 GB GB height reached memory. The subsequent maximum (or minimum) altitude digits flash. 5. Press [+] or [-], the memory resets to the current actual altitude. 6.
