Operation:
The gauge needs the red and black wires connected to light up. It also
requires the sensor connected to the gauge in order to operate. The red wire
should have switched 12 volt power from an ACC. point on the fuse panel. The
black wire should be connected to a good ground point. When the blue wire has
12 volts, it will dim the display for night viewing. The six pin connector plugs into
the mating connector from the compass sensor. The black button found on the
front of the unit is used for calibration. Hold this button in while turning on the
power to enter CAL mode.
True North calibration:
The Dakota Digital compass has a calibration procedure to compensate
for the difference between true north and magnetic north. (This feature can also
be used to compensate for misalignment of the compass with the front of the
vehicle.) The compensation range is from –30 to +30 in 2 degree increments.
The calibration number is stored in a non-volatile memory component that does
not require power to keep its memory.
1. Make sure the ignition key is off so the compass is not lit up.
2. Hold in the button located on the front of the bezel while the key is
turned on.
3. Release the button. The display should show the current cal. number.
4. Press and release the button to increment the cal. number.
5. When the desired cal. number is displayed, press and hold the button.
6. After the display shows "STORED", release the button.
7. The unit will now return to normal operation with the new cal. number
