Connecting the external buzzer
The optional external buzzer (type
XH3-BZ-L970, code no. 000-146-422) sounds
the alarm buzzer in a remove location.
Note: This procedure requires making a hole
in the display unit, which can affect
watertightness. FURUNO cannot guarantee
watertight integrity after this modification is
made.
1. Detach the rear panel and place it out
side up on a workbench.
2. Use a hammer and a Philips head
screwdriver to punch out a hole of ø16 at
the location shown in the illustration
below.

3. Close the rear panel, making sure the
gasket is correctly positioned.
4. Plug in the connector of the external
buzzer to J6 on the DU Board.
5. Seal the hole with sealing compound.
6. Fix the buzzer to the location desired with
two tapping screws.
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.
