electrical Wiring
dc connections
caution:
the rD95 is designed for vehicles with a 12 Volt
negative ground electrical system only!
Refer to the wiring diagram:
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 rD95 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 RD95 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 RD95 is able to maintain it’s memories
when it is switched off using the
PWR
button by drawing
power directly from your battery via the YElloW ‘mEmorY
12 V+’ 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 will vary depending on its
Amp-hour rating and battery condition.
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 rD95 is
a four-speaker system that requires 2 separate wires for
each speaker.
caution:
the use of speakers with an impedance of less
than 4 ohms is not recommended as they will cause excessive
loading of the RD95’s output circuit and may result with the
radio overheating.
A range of GmE speakers are 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.
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 vehicle’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 car radio antenna to the antenna
socket which extends from the rear of the rD95. For
information on a suitable antenna, contact your nearest
GmE branch.
