1. Choose "zone code setting" by pressing function button 

switch 2 on the compass selection screen, and press 
function button switch 3 (ENTER).

2. Find current location and variance zone number on the zone 

map.

3. Enter the zone number to calibrate the compass.
4. If the calibration is made successfully, the display unit 

buzzer will sound twice.

NOTE: If the calibration fails, a message will appear to indicate 
it.
NOTE: Do not install the ski rack, antenna, etc., which are 
attached to the vehicle by means of a magnet. They affect the 
operation of compass.
NOTE: The compass may not indicate the correct compass 
direction in the place shown below:

Demagnetization and correction method

1. Demagnetize the body using a commercial demagnetizer.

2. While keeping the distance between the tip of demagnetizer 

and the roof panel to approximately 5 cm (2.0 inches), move 
the demagnetizer slowly with a sweeping manner on the 
rear-half surface of roof panel.

CAUTION

If the tip of demagnetizer touches the roof panel, the mag-
netizing condition of body becomes worse to the contrary. 
Absolutely avoid this.
3. Slowly draw the demagnetizer apart from the body. Turn off 

the switch of demagnetizer when it is apart from the body 
more than 5 cm (2.0 inches). 

CAUTION

If the demagnetizer is turned off near the body or it is sud-
denly separated from the body, the magnetizing condition 
of body becomes worse to the contrary. Absolutely avoid 
these.
