5.2 DECLINATION ADJUSTMENT SUB MODE
The Wristop Computer allows the user to compensate the difference between true north and magnetic north. This process
is accomplished by adjusting the declination, resulting in the user obtaining correct compass readings.
In the Compass mode, PRESS the [Select] button once to enter this sub mode.
In the Declination Adjustment sub mode (Fig. 23):
• Field 1 displays the declination direction “OFF” where
OFF = no declination; W = West; E = East.
• Field 2 displays declination in degrees.
• Field 3 displays the text “dEC”.
5.2.1 Setting the Local Declination
1. PRESS the [Select] button and hold in for 2 seconds. Located in Field 1, “OFF” will begin to flash.
2. PRESS either the [+] or the [-] button to change the declination direction in Field 1.
3. At the direction desired, PRESS the [Select] button to move to the next setting. Located in Field 2, the degrees will
begin to flash.
4. PRESS the [+] button to scroll the degrees upward or
PRESS the [-] button to scroll the degrees downward.
5. At the degrees desired, PRESS the [Mode] button to accept the changes and exit the setup program.
Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup.
Local Declination is now set.
5.3 CALIBRATING THE COMPASS
A compass calibration should be done when the Wristop Computer is subject to close proximity of magnetic sources,
extreme cold weather, every time the battery is replaced or suspected that other environmental conditions have effected
the compass readings.
Note: We also recommend calibrating the compass before using the compass the first time and every time leaving for a
hike where the compass will be used.
