FLEXIBLE CIRCUIT BOARD REPAIRING
• Keep the temperature of soldering iron around 270 °C during
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 HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The fl exible board is easily damaged and should be handled with
care.
NOTE ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc refl ective surface by the objective lens in tha optical
pick-up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
NOTE FOR THE 28-PIN CONNECTOR
Do not use alcohol to clean the 28-pin connector connecting the
front panel with the main body.
Do not touch the connector directly with your bare hand. Poor contact may be caused.

Cautions
Run all ground (earth) leads to a common ground
(earth) point.
is unit is designed for negative ground (earth) 12 V
DC operation only.
Do not disassemble or modify the unit.
Do not install in locations which interfere with airbag
operation.
Do not get the leads under a screw, or caught in moving
parts (e.g. seat railing).
Before making connections, turn the car ignition off to
avoid short circuits.
Connect the yellow and red power supply leads only
after all other leads have been connected.
Be sure to insulate any loose unconnected leads with
electrical tape for safety.
Do not press on the LCD when installing the unit.
Install the unit with the monitor facing straight forward;
do not install it at a slanted angle.
Notes on the power supply lead (yellow)
When connecting this unit in combination with other
stereo components, the amperage rating of the car
circuit to which the unit is connected must be higher
than the sum of each component's fuse amperage rating.
If no car circuits are rated high enough, connect the unit
directly to the battery.
Connection example
Notes ( -A)
Be sure to connect the ground (earth) lead before connecting the amplier.
The alarm will only sound if the built-in amplier is used.
Note ( -B)
You cannot use multiple auxiliary devices simultaneously, even if they are
connected to dierent terminals.

connecting this unit with the supplied power supply
connection cable
Notes on the control and power supply leads
Memory hold connection
When the yellow power supply lead is connected, power will always be
supplied to the memory circuit even when the ignition switch is turned o.
Notes on speaker connection
may damage the antenna (aerial).
The power antenna (aerial) control lead (blue) supplies +12 V DC when
you turn on the tuner.
If your car has a built-in FM/AM antenna (aerial) in the rear/side glass,
connect the power antenna (aerial) control lead (blue) or the accessory
power supply lead (red) to the power terminal of the antenna (aerial)
booster. For details, consult your car dealer.
A power antenna (aerial) without a relay box cannot be used with this unit.
Before connecting the speakers, turn the unit o.
Use speakers with an impedance of 4 to 8 ohms, and with adequate
power handling capacities to avoid damage.
Do not connect the speaker terminals to the car chassis, or connect the
terminals of the right speakers with those of the left speakers.
Do not connect the ground (earth) lead of this unit to the negative (–)
terminal of a speaker.
Do not attempt to connect the speakers in parallel.
Connect only passive speakers. Connecting active speakers (with
built-in ampliers) to the speaker terminals may damage the unit.
To avoid a malfunction, do not use the built-in speaker leads installed in
your car if they feature a common negative (
speakers.
Do not connect the unit’s speaker leads to each other.
