Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

Installation
Precautions
•Choose the installation location carefully so that the unit will not interfere with normal driving.
•Avoid installing the unit in areas subject to dust, dirt, excessive vibration, or high temperatures, such as
in direct sunlight or near heater ducts.
•Use only the supplied mounting hardware for a safe and secure installation.
Mounting angle adjustment
Adjust the mounting angle to less than 20°.
How to detach and attach the front panel

Connections
Cautions
1
•This unit is designed for negative earth 12 V DC operation only.
•Be careful not to pinch any wires between a screw and the body of the car or this unit or between any
moving parts such as the seat railing, etc.
•Before making connections, disconnect the earth terminal of the car battery to avoid short circuits.
•Connect the yellow and red power input leads only after all other leads have been connected.
•Be sure to connect the red power input lead to the positive 12 V power terminal which is energized
when the ignition key is in the accessory position.
•Run all earth wires to a common earth point.
•Connect the yellow cord to a free car circuit rated higher than the unit’s fuse rating. If you connect this
unit in series with other stereo components, the car circuit they are connected to must be rated higher
than the sum of the individual component’s fuse rating. If there are no car circuits rated as high as the
unit’s fuse rating, connect the unit directly to the battery. If no car circuits are available for connecting
this unit, connect the unit to a car circuit rated higher than the unit’s fuse rating in such a way that if the
unit blows its fuse, no other circuits will be cut off.
•Be sure to insulate any loose unconnected wires with electrical tape for safety.
•When installing a car without ACC (accessory) position on the ignition key switch, connect the red
power input lead to the +12 V power terminal which is energized at all times with the yellow lead.
Warning when installing in a car without ACC (accessory) position on
the ignition key switch
Be sure to press (OFF) on the unit for two seconds to turn off the clock display after turned off the
engine.
When you press (OFF) momentarily, the clock display does not turn off and this causes battery wear.
Frequency select switch (XR-CA340 only)
The AM (FM) tuning interval is factory-set to the 9 K (50 K) position. If the frequency allocation system of
your country is based on 10 kHz (200 kHz) interval, set the switch on the bottom of the unit to the 10 K
(200 K) position before making connections.
Change the position with a jeweler’s screwdriver, etc.
Note
When you change the position of the switch, be sure to press the reset buttons after the connections are
completed.
Reset button
When the installation and connections are over, be sure to press the reset button with a ballpoint pen, etc.

of the ignition key switch
Notes
• If there is no accessory position, connect to the +12 V power (battery)
terminal which is energized at all times.
Be sure to connect the black earth lead to it first.
• When your car has a built-in FM/AM aerial in the rear/side glass, see
“Notes on the control and power supply leads.”
Notes on the control and power supply leads
• The power aerial control lead (blue) supplies +12 V DC when you turn on the unit.
• When your car has a built-in FM/AM aerial in the rear/side glass, it is necessary to connect the power aerial
control lead (blue) or the accessory power input lead (red) to the power terminal of the existing aerial booster.
For details, consult your dealer.
• A power aerial without a relay box cannot be used with this unit.
Memory hold connection
When the yellow power input lead is connected, power will always be supplied to the memory circuit even when
the ignition switch is turned off.
Notes on speaker connection
• Before connecting the speakers, turn the unit off.
• Use speakers with an impedance of 4 to 8 ohms, and with adequate power handling capacities. Otherwise, the
speakers may be damaged.
• Do not connect the terminals of the speaker system to the car chassis, and do not connect the terminals of the
right speaker with those of the left speaker.
• Do not attempt to connect the speakers in parallel.
• Do not connect any active speakers (with built-in amplifiers) to the speaker terminals of the unit. Doing so may
damage the active speakers. Be sure to connect passive speakers to these terminals.
