| Note: This unit is for vehicles with a 12-volt
battery and negative grounding. Before installing it in a
recreational vehicle, truck, or bus, check the battery
voltage.
To avoid shorts in the electrical system, be sure to
disconnect the minus (-) battery cable before beginning
installation. Refer to the owner’s manual for details on
connecting the power amp and other units, then make
connections correctly. Secure the wiring with cable clamps
or adhesive tape. To protect the wiring, wrap adhesive tape
around them where they lie against metal parts.
Route and secure all wiring so it cannot touch any moving
parts, such as the gear shift, handbrake and seat rails. Do
not route wiring in places that get hot, such as near the
heater outlet. If the insulation of the wiring melts or gets
torn, there is a danger of the wiring short-circuiting to
the vehicle body.
Don’t pass the yellow wire through a hole into the engine
compartment to connect to the battery. This will damage the
wire insulation and cause a very dangerous short.
Do not shorten any wires. If you do, the protection
circuit may fail to work when it should.
Never feed power to other equipment by cutting the
insulation of the power supply wire of the unit and tapping
into the wire. The current capacity of the wire will be
exceeded, causing overheating.
When replacing fuse, be sure to use only fuse of the
rating prescribed on the fuse holder.
Since a unique BPTL circuit is employed, never wire so
the speaker wires are directly grounded or the left and
right (-) speaker wires are common.
If the RCA pin jack on the unit will not be used, do not
remove the caps attached to the end of the connector.
Speakers connected to this unit must be high power types
with minimum rating of 50 W and impedance of 4 to 8 ohms.
Connecting speakers with output and/or impedance values
other than those noted here may result in the speakers
catching fire, emitting smoke or becoming damaged.
When this product’s source is switched ON, a control
signal is output through the blue/white wire. Connect to an
external power amp’s system remote control or the car’s
Auto-antenna relay control terminal (max. 300 mA 12 V DC).
If the car features a glass antenna, connect to the antenna
booster power supply terminal.
When an external power amp is being used with this
system, be sure not to connect the blue/white wire to the
amp’s power terminal. Likewise, do not connect the
blue/white wire to the power terminal of the auto-antenna.
Such connection could cause excessive current drain and
malfunction.
To avoid short-circuiting, cover the disconnected wire
with insulating tape. Especially, insulate the unused
speaker wires without fail. There is a possibility of
short-circuiting if the wires are not insulated.
To prevent incorrect connection, the input side of the
IP-BUS connector is blue, and the output side is black.
Connect the connectors of the same colors correctly.
The black wire is ground. Please ground this wire
separately from the ground of high-current products such as
power amps. If you ground the products together and the
ground becomes detached, there is a risk of damage to the
products or fire.
ANT Power Antenna Wire (Blue) Connect this wire to
the +B terminal of your power antenna, if applicable. Power
for Electric Antenna. Output from the stereo +12 V (maximum
150 - 300mA) power supply for automatic or electronic
antennas.
REM Remote Turn-On Wire (Blue/White) Connect this
wire to the remote turn-on wire of your amplifier or signal
processor.
B+ Battery Wire (Yellow) Connect this wire to the
positive (+) post of the vehicle’s battery. Memory Power
(12V direct from Battery). Connects the radio directly to
the battery.
ACC Switched Power Wire (Ignition) (Red) Connect
this wire to an open terminal on the vehicle’s fuse box or
another unused power source which provides (+) 12V only when
the ignition is turned on or in the accessory position. +12V
Main Power (Switched via Ignition key). +12 V with the
ignition key is in the ACC or ON position.
GND Ground Wire (Black) Connect this wire to a
good chassis ground on the vehicle. Make sure the connection
is made to bare metal and is securely fastened using the
sheet metal screw provided.
ILLUMI DIMMER Illumination Wire (Orange This wire
may be connected to the vehicle’s instrument cluster
illumination wire. This will allow the backlighting of this
unit to dim whenever the vehicle’s lights are turned on.
Dial-light illumination (car side light circuit). +12 V
input on the car when the lights are on. For some it
actually illuminates the radio display - the others can dim
the lights. If the dashboard of your car has a light control
function, this pin should be connected in order to regulate
the brightness. The wire from lighting a cigarette lighter
can be used for the same purposes.
SCV Speed-dependent volume control, speed signal
This pin is used in some radio equipment to automatically
boost up the volume. It needs the output from the speed
sensor. Note: If the speedometer stops working when the
radio is connected, then the pin is probably grounded
because radio probably uses this pin for another function,
except for GALA.
MUTE Mute from Cell-Phone. This pin is used to
silence the audio, earthed by some other external components
such as a mobile phone that is connected to the radio.
REV the reversing light switch. +12 V input on the
radio with the ignition switched on the ignition and the car
is in gear to move backwards. Used for reversing lamp signal
on Becker radios with navigation.
