Note
: Calibration should be performed on a level sur-
face. The size of the circles or the direction your vehicle
is pointing when beginning or ending the circles does not
matter. The circles do not need to be perfect circles,
but must be completed in the same direction. It is also
important that each circle takes a minimum of 20 seconds
but less than 1 minute to complete.
Compass Display
The compass displays eight cardinal points (
N , N E ,
E , S E , S , S W , W , N W
) and the corre-
sponding numeric heading in 5-degree increments (
3 4 0 °
,
3 4 5 °
, etc.).
The RX5000 also detects when outside magnetic interfer-
ence is compromising compass accuracy by flashing the
D I S T O R T
. message. This may occur when driving
over a bridge, under an overpass, over railroad tracks or
within close proximity to something with strong magnetic
field. Once the vehicle has moved away from the source of
interference, the RX5000 will be accurate again.
However, if the
D I S T O R T
. message is continuously
displayed, it is usually a sign that there has been a significant
change in magnetic fields and recalibration is necessary.
