Connect the YELLOW wire directly to the positiveterminal of the vessel’s battery, or to a point that has+12 Volts available at all times. This lead maintains thememories within the GR9200 and is the main powersource for the unit.2. Connect the Red wire to the vessels +12 V supply viaan appropriate isolating switch or circuit breaker. Thislead enables the radio to be switched ON and OFF.Alternatively, this wire can be connected directly to thebattery’s positive terminal and the GR9200 switched ONand OFF using it’s own controls.3. Connect the Black wire to the battery’s negative terminalor to the common negative bus in the electrical system.Important: Your GR9200 is able to maintain it’s memorieswhen it is switched off by drawing power directly fromyour battery via the Yellow ‘Memory’ lead. Althoughthe memory backup current is very small (about 10 mA)it may eventually discharge your battery if left connectedindefinitely. The time taken to completely discharge yourbattery could vary depending on its Amp-hour rating andbattery condition.If you do not run your boat’s motor regularly or your batteryis not kept charged between outings (e.g. Solar or windcharger), we recommend you disconnect the Yellow leadeach time you secure or trail your boat. This is easily doneby connecting the Yellow ‘Memory ’ lead via a Masterswitch, which can be switched off after each outing. Thiswill mean you will loose all your preset station memoriesand clock settings.The blue wire on the wiring loom supplies 12 Volts whenthe GR9200 is switched on and can be used to turn on anexternal device, like the GME GA9800 marine amplifier, orenable the back light on the GME RCU9200 wired remote.PAGE 8 instruction manual GR9200 series
