3.4 Adjustments

After you have installed the radar, do the
heading alignment and timing adjustment. If
you are connecting external equipment,
follow "NMEA port setup, GPS WAAS setup"
(for GP-320B) also.
Heading alignment
You have mounted the antenna unit facing
straight ahead in the direction of the bow.
Therefore, a small but conspicuous target
dead ahead visually should appear on the
heading line (zero degrees).
In practice, you will probably observe some
small error on the display because of the
difficulty in achieving accurate initial
positioning of the antenna unit. The following
adjustment will compensate for this error.
1. Turn on the power while pressing and
holding down the [MENU/ESC] key.
Continue pressing the [MENU/ESC] key
until the Installation menu appears.
