ELECTRICAL WIRING
DC Connections
Caution:
The RC900 is designed for vehicles with a 12 volt
negative ground electrical system only!
Referring to the wiring diagram on this page:
1. Connect the YELLOW wire directly to the positive
terminal of the vehicle’s battery, or to a point that has
+12 Volts available at all times. This lead maintains
the memories within the RC900 and is the main power
source for the unit.
2. Connect the RED wire to the vehicle’s +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 RC900 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.
NOTE: The blue wire on the wiring loom supplies 12 volts
when the RC900 is switched on and can be used to turn on
an external device, like the GME GA9800 amplifier.
Speaker Connections
When connecting the speakers, observe the correct polarity as
shown in the diagram above right. Incorrect polarity will result in a
reduction of bass response and stereo effect. The use of speakers
with an impedance of less that 4 Ohms is not recommended, as
they will cause excessive loading of the RC900’s output circuit
and may result in the radio overheating.
CAUTION: The RC900 is a four-speaker system that
requires 2 separate wires for each speaker.
A range of GME speakers is available from your local
GME retailer.
Connect all four speakers as shown in the diagram above.
Adjust the Fader control for the required front/rear balance.
IN STALL ATION
PRECAUTIONS
If you are connecting your RC900 for the first time or
have just reconnected your vehicle battery and you are
experiencing problems with the unit’s operation, we
suggest you try resetting the unit. The reset button is
located on the front panel below the volume control. Gently
press the reset button with a paper clip or similar object.
The preset station memories and clock time are retained
only while the yellow ‘Memory’ lead is connected to a
continuous + 12 V DC supply (see Electrical Wiring section).
If the battery is disconnected or switched off at the master
switch, or the unit is removed from the vehicle, the station
memories will be lost and the clock will need to be reset.
HANDLING COMPACT DISCS
•
Handle the CD by it’s edge, avoid touching the
disc surface.
•
Store your CDs away from direct sunlight or heat
sources. Keeping the CD in it’s original case will help to
keepit flat.
•
Clean the CD with a soft cloth from the centre to the
outer edge, (see diagram) rather than in a ci lar
motion. Do not use solvents.
MOISTURE /CONDENSATION
Your RC900 uses optical laser technology. Occasionally
damp or humid conditions may cause condensation to
appear on the lenses inside the unit. Should this occur, the
unit might not operate correctly. Simply eject the CD and
leave the unit turned on for a while until the
moisture evaporates.
LOCATION
GME recommends that the unit should be mounted in a
position that is free from direct sunlight and
excessive vibration.
INSTALLING RC900 INTO A DIN SIZED RECESS
The RC900 is designed to be installed with the mounting
accessories provided.
1. Remove the front panel surround.
2. Insert release keys between the RC900
and the DIN sized mounting frame, so that the locking
tabs on the mount frame are released. Remove the
RC900 from the mounting frame.
3. Insert the mounting frame into the DIN sized recess.
4. Bend the tabs to secure the frame in the recess.
