INSTALLING AND REPLACING OF
BATTERY
The EB833 operates with 2 (two) CR-2032 Lithium
batteries that are included with all new units. 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.

Follow these steps to install or replace batteries:
1. Open battery cover located at the back of the unit by
removing screws.
GENERAL OPERATION OF THE ALTIMETER
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.
In Altimeter Mode, by detecting changes in air pressure,
the EB833 determines
a
given altitude level.
2. Insert 2 (two) new CR-2032 Lithium batteries.
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.
3. Replace the battery cover.

UNITS OF MEASUREMENT FOR ALTITUDE
ALTITUDE CALIBRATION
Altitude measurements can be displayed in feet (ft) or
meters (m).
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 change the altitude units of measure:
1. In Normal Altitude Display.
To calibrate the altitude:
2. Simultaneously, press and hold the [+] and [-] to
select between meters or feet.
1. In Normal Altitude Display.
2. Press and hold [ALT] and [TIME] simultaneously for
about2seconds. TheCALHxindicatorshowsonthe

3. Press [+] or [-] to adjust the altitude reading by 1
meter. For rapid acceleration of measurement
adjustments, press and hold.
ABOUT THE ALTITUDE CHANGE GRAPH

a 2-hour time period. Each horizontal line represents
pressure changes equal to + /- 200m.
4. Press [ALT] to confirm and return to the Altitude
Display.
Example:
Point C: A point where the altitude, as indicated by a
marking stone or post, is 1500m. At this point
set the current altitude to 1500m.

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.
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:
Point A: Atthispoint, resettheAltitudeChangeMemory

Altitudereadingsmaybeaffectedbyairpressurechange.
Sudden changes in pressure, temperature and weather
may cause an inaccurate altitude reading.

NOTES ON THE BAROMETER FUNCTIONS
Barometer readings may be affected by a change in
altitude.
The unit cannot distinguish between a change in air
pressure caused by weather patterns or by a change in
altitude. However, accurate functioning of the unit can
be maintained by following a few simple steps.
( 2 HOURS PER COLUMN )
To ensure that accurate barometric readings are
maintained:
An upward or downward direction of the vertical bars
may illustrate a changing pressure trend. Subsequently,
this may indicate changes in weather conditions.
However, as stated previously, caution needs to be
taken when attempting to predict weather forecasts.
When the unit is stationed at the same elevation for
extended periods, it is advised to keep the unit in
Barometer Mode.
In addition to maximizing the weather forecasting
capabilities the unit requires less power to function.
Subsequently battery life may be extended.
