TURN ON WATCH (FIRST-TIME USE ONLY)
Press and hold any key for 2 seconds to activate the LCD
display.
GETTING STARTED
The watch uses a 1 x CR2032 lithium battery, which has
already been installed. See below for battery warnings.
LOW BATTERY
ICON DESCRIPTION
The watch battery is low.

Appears when the battery
is too low to operate the
sensor. “- -” is shown instead
of temperature and compass
values.
To replace battery:
1. Using a coin, remove battery compartment lid by twisting
counter-clockwise until it clicks out of place.
2. Remove the old batteries and insert the new matching
the polarities.
3. Replace the lid by twisting it clockwise until firmly in
place.
NOTE When battery is replaced it is important to re-
calibrate the magnetic sensor.

COMPASS
ABOUT THE COMPASS
The compass shows the bearing of your position in degrees
due North. The outer circumference of the display consists
of 60 segments that graphically show your bearing. Three
lit segments represent South whereas one lit segment
represents North, as shown below.

COMPASS AND CALIBRATION
Before the compass is first used, we recommend that you
calibrate the compass sensor.
To calibrate the compass sensor:
• Press MODE to navigate to the Set up mode.

• Press SET to navigate to Calibration mode option.
• Press and hold SET to begin calibration of the compass.
Rotate the watch counter clockwise at the same speed
as the moving segments around the circumference of
the display. The rotation will be finished once you have
performed 1 ¼ turns and the display will appear as shown
below when nearing the end of its calibration.
SET
MODE
NOTE The compass should be calibrated:
• Before you use it for the first time.
• When the battery is replaced.
• Before you leave for an extended outdoor activity.
• Whenever it is exposed to strong magnetic sources,
extreme cold, or you suspect that other environmental
conditions have affected the compass readings.
• If you notice that the compass is not showing the
direction correctly.
TO SET THE TRUE NORTH CALIBRATION
When you do not know the declination angle, the true north
calibration function can be used to compensate for the
difference between magnetic and true north. All you need
to know is the direction of true north (this can be found from
landmarks in your immediate vicinity). Setting the true north
calibration makes the compass reading more accurate.
1. Press MODE to navigate to Set up mode.
2. Press SET to navigate to True north mode option.
3. Turn the compass to the direction of true north and
press ST / SP / +.
To toggle True north calibration ON / OFF:
• Press MODE to navigate to Set up mode.
• Press SET to navigate to True north mode option.
• Press ST / SP / + to toggle true north mode to ON /
OFF
NOTE If the declination angle is turned ON, the True north
function will automatically turn itself OFF and vice-versa.
DECLINATION ANGLE
ABOUT DECLINATION
Declination is the angle between where a compass needle
points (magnetic North Pole) and the true North Pole. The
declination angle can vary from 0-30 degrees East (E)
or West (W) and can be found on most maps or on the
Internet.
For declinations in the United States:
http://www.ngdc.noaa.gov/seg/geomag/jsp/Declination.jsp
1. Enter your zip code in the area provided
RA126 IM EN R5.indd 8 2007.7.27 12:21:52 PM

2. Click “Get Location”
3. Scroll down and click “Compute”
For declinations in Canada:
http://www.geolab.nrcan.gc.ca/geomag/apps/mdcal_e.php
When you set the declination angle on the compass you
compensate for the difference between true and magnetic
north. This increases it’s accuracy.
To set the declination angle:
1. Press MODE to navigate to Set up mode.
2. Press SET to navigate to Declination mode option.
3. Press and hold SET to enter settings mode.
4. Press ST / SP / + or COMPASS / - to toggle settings.
The setting options are as follows: WEST / EAST
declination angle.
5. Press SET to confirm.
BEARING TRACKING SYSTEM
ABOUT THE BEARING TRACKING SYSTEM
The bearing tracking system enables you to lock onto
a bearing, which you will be able to relocate using the
compass. By locking the bearing you can see when you
deviate from your course and how much you need to
correct it to get back on track.
TO SET THE BEARING TRACKING SYSTEM
1. Press MODE to navigate to Set up mode.
2. Press and hold SET to enter setting mode.
• The top figure shows your last bearing locked.
• The bottom figure shows your current bearing.

SET
MODE
3. Point the compass in the desired direction and press
SET.
4. Press SET to fine tune the bearing. Press ST / SP / + to
increase and COMPASS / - to decrease the bearing.
5. Press SET to confirm.
6. In the Compass mode, the locked bearing will appear
instead of the cardinal reading.
Once the bearing tracking system has been set, the
compass segments on the display will show how far you
deviate from your locked course. See the examples below:
A. The locked bearing is 94 and the current bearing is
94.
B. Your locked bearing is 94 and your current bearing is
120.
