With a magnetic heading sensor (PG-500/700 etc.), magnetic variation information is nec-
essary to display true heading data. In almost all cases, a GPS will be connected to the
NAVpilot and the GPS will send this variation information to the NAVpilot automatically.
Therefore, select "AUTO". In special cases where a manual variation is required, you may
input these values manually. Note that this selection is only effective when the heading
indication for the NAVpilot is selected to "TRUE".
When true heading display is selected in the [DISPLAY SETUP] menu, the NAVpilot will
display true heading information even though the NAVpilot may be connected to a mag-
netic heading sensor. This is very valuable when connecting a FURUNO radar FAR-21X7
series to the NAVpilot because these radars cannot be set for a magnetic heading input
and the "Waypoint Lollipop" will only align properly when true heading is used.
If you have selected the FURUNO PG-500/700 as a heading sensor, do the procedure
below to calibrate the compass and get automatic distortion compensation. Otherwise, go
to step 4.
• The procedure is not applicable to other heading sensors.
• It is not necessary to perform any adjustments locally at the PG-500/700. NAVpilot has
full control of these heading sensors.
1. Rotate the knob to select [COMPASS SETUP] then push the knob.
2. [SELECT COMPASS] is selected to [1ST]. Calibrate the 1st compass and then cali-
brate others.
