INTRODUCTION

Thank you for your purchase of the Altimeter / Barometer (EB833). Designed to be durable, this unit is constructed for rugged outdoor use.

The EB833 has three primary functions.

1. Altimeter

- Functions related to altitude measurement.

2. Barometer and Weather Forecast Device

- Functions related to weather forecasts and atmospheric pressure.

3. Clock, Calendar, and Count-Up Timer

- Functions related to time, date, and count-up timer.

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.

EB833(EN3) 8/31/04, 3:40 PM2

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.

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.

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.

Upon removal, the display will show a full-segment display for 3 seconds; it will then enter the Normal Altitude Display.

EB833(EN3) 8/31/04, 3:40 PM3

FULL SEGMENT DISPLAY

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.

3. Replace the battery cover.

A battery-low indicator [ 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.

6. Press [ALT] again, the unit will return to the Normal Altitude display.

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 meter. For rapid acceleration of measurement adjustments, press and hold.

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.

NOTE The unit will return to Normal Altimeter Display if no buttons are pressed for one-minute during the calibration sequence.

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 + /- 200m.

( 2 HOURS PER COLUMN )

The Altitude Change Graph is viewed in all the Altimeter Mode displays.
