DISPLAY REFERENCE FOR ZONE
1. Briefly press the button to toggle the display ‘‘ON/
OFF’’.
NOTE: The compass display will default ‘‘ON’’ at
each new ignition cycle.
2. With the BLUE CENTER LED displayed, press and
hold the button for six seconds, or until a RED
CENTER LED is displayed in the compass window,
then release the button. While the RED CENTER
LED is ‘‘ON’’ release the button. The compass is
now in calibration mode. To calibrate, drive the
vehicle in circles at less then 5 mph (8 km/h) until a
BLUE CENTER LED is displayed. Typically
2
5 circles are required.
3. Find your current location and determine the
correct zone number, for your geographic area,
from the table ‘‘DISPLAY REFERENCE FOR ZONE’’.
Press and hold the button for three seconds (until
ALL DIRECTION BLUE LEDs BLINK), then release
the button. The BLINKING LED(s) displayed is/are
the current zone value. (see the table ‘‘DISPLAY
REFERENCE FOR ZONE’’)
4. If a new zone value is desired, briefly press the
button to increment the displayed value (Range
1
15) until you find your desired zone setting.
No button activity for four seconds ends the zone
entry mode. The compass display will return to
normal operation and the new zone number will be
set.
NOTE: See the table ‘‘DISPLAY REFERENCE FOR
ZONE’’.
5. Zone selection is required to compensate for the
difference between magnetic North and geographic
North. This deviation is referred to as declination
and can be compensated for by selecting the zone
that corresponds with your area.
See this illustration. Each zone represents about
5 degrees of declination.
