Connecting The Unit - Pioneer PRS-A900 Mode D'emploi

Connecting the Unit

CAUTION
• Disconnect the negative (–) terminal of the bat-
tery to avoid the risk of short-circuit and damage
to the unit.
• Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around it where they lie against metal parts.
• Do not route wires where they will get hot, for
example where the heater will blow over them. If
the insulation heats up, it may become damaged,
resulting in a short-circuit through the vehicle
body.
CAUTION
To prevent damage and/or injury
• Do not ground the speaker wire directly or con-
nect a negative (–) lead wire for several speakers.
• This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recre-
ational vehicle, truck or bus, check the battery
voltage.
• If the car stereo is kept on for a long time while
the engine is at rest or idling, the battery may go
dead. Turn the car stereo off when the engine is at
rest or idling.
• If the system remote control wire of the amplifier
is connected to the power terminal through the
ignition switch (12 V DC), the amplifier will
always be on when the ignition is on— regardless
of whether the car stereo is on or off. Because of
this, the battery could go dead if the engine is at
rest or idling.
