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
Before installing the unit, detach the front panel.
A To detach
Before detaching the front panel, be sure to press
(OFF). Press (RELEASE), then slide the front panel a
little to the left, and pull it off towards you.
B To attach
Attach part
A of the front panel to part B of the unit as illustrated and push the left side into position
until it clicks.

Connections
Cautions
·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.
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.
Note
When you change the position of the switch, be sure to press the reset buttons after the connections are
completed.
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.
Reset button
When the installation and connections are over, be sure to press the reset button with a ballpoint pen, etc.
Change the position with a jeweler's screwdriver, etc.
Cautions
·Cautionary notice for handling the bracket
1.
Handle the bracket carefully to avoid injuring your fingers.
·Remove the protection collar
5 before installing.
Release the catch lock as illustrated.
