notice.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick­up block. Therefore, when checking the laser diode emission, ob­serve from more than 30 cm away from the objective lens.

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.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block.

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 to avoid its
damage.

•Do not connect the speaker terminals to the car
chassis, or connect the terminals of the right speakers
with those of the left speaker.

•Do not connect the ground lead of this unit to the
negative (–) terminal of the speaker.

•Do not attempt to connect the speakers in parallel.

•Connect only passive speakers. Connecting active
speakers (with built-in amplifiers) to the speaker
terminals may damage the unit.

•To avoid a malfunction, do not use the built-in speaker
wires installed in your car if the unit shares a common
negative (–) lead for the right and left speakers.

•Do not connect the unit’s speaker cords to each other.

Note on connection

If speaker and amplifier are not connected correctly,
“Failure” appears in the display. In this case, make sure
the speaker and amplifier are connected correctly.
