Caution: the Gr9200 is designed for vessels with a 12 Volt
negative ground electrical system only!
Referring to the wiring diagram on this page:
1. C onnect the YELLOW wire directly to the positive
terminal of the vessel's battery, or to a point that has
+12 Volts available at all times. This lead maintains the
memories within the Gr9200 and is the main power
source for the unit .
2 . connect the rED wire to the vessels +12 V supply via
an appropriate isolating switch or circuit breaker. This
lead enables the radio to be switched ON and OFF.
Alternatively, this wire can be connected directly to the
battery's positive terminal and the GR9200 switched ON
and oFF using it's own controls .
3 . connect the BLACK wire to the battery's negative terminal
or to the common negative bus in the electrical system.

important: Your GR9200 is able to maintain it's memories
when it is switched off by drawing power directly from
your battery via the YElloW 'Memory' lead. Although
the memory backup current is very small (about 10 mA)
it may eventually discharge your battery if left connected
indefinitely. The time taken to completely discharge your
battery could vary depending on its Amp-hour rating and
battery condition.
If you do not run your boat's motor regularly or your battery
is not kept charged between outings (e.g. Solar or wind
charger), we recommend you disconnect the YElloW lead
each time you secure or trail your boat. This is easily done
by connecting the YElloW 'Memory ' lead via a Master
switch, which can be switched off after each outing. This
will mean you will loose all your preset station memories
and clock settings .
The blue wire on the wiring loom supplies 12 Volts when
the GR9200 is switched on and can be used to turn on an
external device, like the GME GA9800 marine amplifier, or
enable the back light on the GME RCU9200 wired remote.
