SERVICE NOTES

CAUTION

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

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 dam­aged by heat.

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.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!

• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

• Connect the MAIN board (CNP301) and the SER VO board (CN2)
with the extension cable (Part No. J-2502-076-1).

1 To a metal surface of the car

First connect the black ground lead, then connect the yellow
and red power input leads.

2 To the power antenna control lead or power

supply lead of antenna booster amplifier

Notes

•

It is not necessary to connect this lead if there is no power
antenna or antenna booster, or with a manually-operated
telescopic antenna.

•

When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply
leads.”

3 To AMP REMOTE IN of an optional power

amplifi er

This connection is only for amplifi ers. Connecting any other
system may damage the unit.

4 To the +12 V power terminal which is

energized in the accessory position 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 ground lead to a metal

surface of the car fi rst.

•

When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply
leads.”

5 To the +12 V power terminal which is

energized at all times

Be sure to connect the black ground lead to a metal surface
of the car fi rst.

Notes on the control and power supply leads

•

The power antenna control lead (blue) supplies +12 V DC
when you turn on the tuner.

•

When your car has built-in FM/AM antenna in the rear/side
