Connect all four speakers as shown in the previous diagram.
Adjust the Fader control for the required front/rear balance.
If you wish to connect only two speakers, connect these to
the Rear speaker wires. The remaining speaker wires should
be insulated to ensure they cannot short circuit together or
to the vessel’s 12 Volt or negative electrical Bus. If using only
two speakers, adjust the Fader control to the rear speakers.
Antenna Connections
Connect an AM/FM marine antenna to the antenna
socket which extends from the rear of the GD9520. For
information on a suitable antenna, contact your nearest
GME branch or marine retailer.
Reset Button
When the installation is complete, remove the front panel
and press the Reset button using a paper clip or similar
object (see ‘INSTALLATION PRECAUTIONS’ on page 4).
This will ensure the GD9520 is ready to operate for the first
time. If at any time the controls do not seem to work (after
replacing the vessel’s battery for example), press the Reset
button to reset the microcomputer inside the GD9520.
FUSE REPLACEMENT
If any of the fuses blow, replace them with a standard
30 mm 3 AG type of the same rating, if the fuse blows a
second time contact your retailer.
The following fuse ratings are used:
-Yellow ‘Memory 12 V +’ lead: 15 Amp.
-Red ‘Ignition Switch ACC’ lead: 1 Amp.
