Connect the RED power lead to the Positive (+) side of the
battery or to an accessory point in the vessel’s fuse box.
Connect the BLACK power lead to the Negative (-) side of
the battery or to a ground point in your vessel’s fuse box.
NOTE:
The RED power lead is fitted with a 10 Amp fuse.
If the fuse blows, use only a standard 10 Amp (3AG type)
fuse as a replacement. Use of higher rated fuses or ‘slow
blow’ types could result in damage to your radio which
would void the warranty.
Connect the antenna cable to the rear antenna socket on
the radio using a PL259 coaxial connector.
If required, an SPK600 extension speaker may be installed
near the steering position or outside the cabin to improve
the reception clarity in those areas. The SPK600 is
specifically designed for the GX600D with a watertight
connector to match the extension speaker socket on the rear
of the radio.
Noise Suppression
The inherent design of VHF FM radios results in a high
level of resistance to ignition and electrical interference.
However in some installations it may be necessary to
take additional steps to help reduce or eliminate noise
interference. During installation, try to route the DC battery
leads, the antenna lead or any accessory wires away from
the engine compartment, ignition or alternator wiring. If the
noise continues, it may be necessary to fit a suppression kit.
Contact your local marine dealer for more information.
Similarly, if the interference you are experiencing is from
other electronic equipment such as a depth sounder, try to
keep the depth sounder’s DC leads and transducer cable
well away from your GX600D’s wiring.
