DC connections
Connect the
RED
power lead to the Positive (+) side of the battery or to an accessory point in
the vessel or vehicle’s fuse box.
Connect the
BLACK
power lead to the Negative (-) side of the battery or to a ground point in
your vessel or vehicle.
IMPORTANT:
The RED power lead is fitted with a 10 Amp fuse. If the fuse blows, use only a
standard 10 Amp (3AG) fuse as a replacement. Use of a higher rated fuse or a slow-blow type
could result in damage to your radio which would void the warranty.
Panel socket
The panel socket should be mounted on the dashboard next to the LCD controller microphone
mounting location. Mark the correct location for the socket, checking that there is a clear space
behind the panel. Drill a 28 mm hole in the dashboard.
Slide the PCB into the rear of the socket ensuring it is correctly located in the guides (it may be
easier to fit into the guides now rather than after the socket is mounted).
Insert the panel socket through the hole in the panel from the front and secure it using the
washer and castellated nut. Hand-tighten firmly - do not over tighten.
Finally, insert the ‘O’ ring into the rear cap and screw into place to secure the PCB. Hand-tighten
firmly.

Connect the 8 pin socket on the main unit to the 8 pin connector at the rear of the panel socket
using the 500 mm interconnecting lead. Fit the cable grommets to provide protection from
water ingress.
LCD controller microphone
Position the microphone cradle in the desired location and mark the three screw holes. Drill the
holes and fix the bracket with screws. Slide the microphone downwards into the cradle.
Plug the 8 pin connector into the front of the panel socket and fit the grommet to protect
against water ingress.
NOTE:
A standard microphone clip is also supplied as an alternative to installing the full cradle.
The mounting clip can be screwed to the panel and fixed with ‘3M’ double-sided adhesive tape
(not included).
