During initial packaging, the batteries were insulated with a red tape so as to maximize the shelf life of the product. 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. [. . . ] 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. Press [ALT], and proceed to the accumulative vertical ascent / decent memory. Press [ALT] a last time and the unit returns to the Altitude Max (or Min) Memory Display. Note: The EB833 will return to Altitude Max/Min Memory Display if no buttons are pressed for 1 minute. 5. Press [+] or [-] to deactivate the alarm (the disappears) or [+] or [-] to activate the alarm ( indicator appears). indicator 6. The indicator will appear and the alarm will activate at the specified elevation. altitude, the Note: The unit will return to the Altimeter Display if no buttons are pressed for 2 minutes. The altitude alarm setting ranges is between ­500m and 7000m. The Altitude Alarm The Altitude Alarm can be set to activate when a specific altitude is reached. Press [ALT] 8 Altitude Sampling Rate The EB833 automatically samples altitude level at a rate of 2 seconds or 15 minutes. When detecting a significant change in altitude, the unit will automatically increase the Altitude Sampling Rate to 2-second intervals. When maintained at the same elevation for 10 minutes or longer, the device will automatically decrease the rate at which altitude samples are taken. To manually force a change in the frequency at which altitude samples are taken: 1. Normal Barometric Display The first display in Barometric Display Mode. Note: The unit will automatically enter Normal Barometric Display when first entering the Barometric Mode. Display shows: BARO icon Current pressure Pressure change trend graph Weather forecast indicators Current Time NORMAL BAROMETRIC DISPLAY Current Temperature * Previous barometric levels can be displayed for up to 12 hours. Press [+} or [-] to display previous barometric levels at one hour intervals for the past 12 hours. Press [BARO] again, to return to the Normal Barometer Display. Barometric Calibrations At sea level or near a reliable source like a weather station, the barometer can be calibrated. The "CAL Po" will be displayed and the current barometric digits will flash. Press [BARO] again to view the Barometric Pressure History Display Display shows: Units of Measure for Barometric Pressure Barometric units of measurement can be displayed as mb, hpa, and inHg. Simultaneously press again until the desired units have been selected. Corresponding barometric pressure level at the indicated time BAROMETRIC HISTORY DISPLAY One hour previous* 10 About The Pressure Change Graph The EB833 can display barometric pressure levels at intervals for the past 12 hours. Each vertical bar on the Pressure Change Graph represents a 2-hour time period. [. . . ] If the unit comes in contact with water, dry it immediately with a soft lint-free cloth. Abrasive cleaning agents may scratch the plastic parts and corrode the electronic circuit. Do not subject the unit to excessive: force, shock, dust, temperature, or humidity. Such treatment may result in malfunction, a shorter electronic life span, damaged batteries, or distorted parts. [. . . ]
