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.

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.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free 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 fl ow)

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.

Design and specifi cations are subject to change without
notice.

SERVICING NOTES

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.

NOTES 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 the optical
pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

CHUCK PLATE JIG ON REPAIRING

On repairing CD section, playing a disc without the CD lid, use
Chuck Plate Jig.

• Code number of Chuck Plate Jig : X-4918-255-1

TEST MODE

CFD-RG880CP

[MC COLD RESET]

The cold reset clears all data including preset data stored in the
memory to initial conditions. Execute this mode when returning
the set to the customer.

Procedure:

1. In the standby status, press the [POWER] button to turn the
power on.

2. Press three buttons of [x], [MODE] and at last [POWER] si­multaneously.

3. When “RESET” appears, the machine enters standby status.

[PANEL TEST MODE]
Enter The Panel Test Mode
Procedure:

1. In the standby status, press the [POWER] button to turn the
power on.

2. Press three buttons of [REPEAT], [x], and [DSPL/ENT] si­multaneously.

3. When the panel test mode is activated, LEDs and segments of
LCD are all turned on.

Version Check
Procedure:

1. In the panel test mode (all LEDs and segments of LCD are
turned on), press the [ROCK] button.

2. On the LCD, date and version are displayed “xxxxxxxx”. For
example, “0305V001”.

3. From this status, press the [DANCE] button, and the destina­tion is displayed. For example, “1024 MX2”.

4. To release from this mode, press three buttons of [REPEAT],
[x], and [DSPL/ENT] simultaneously.

[CD SERVICE MODE]

This mode can move the SLED of the optical pick-up, and also can
turn the optical pick-up laser power on and off.

Procedure:

1. Press the [POWER] button to turn the power on.

2. Press the [CD] button to select the CD mode.

3. Press three buttons of [x], [VOL +], and [SALSA] simultane­ously.

4. It enters the CD service mode and displays “SE MODE”.

5. To exit from this mode, press three buttons of [x], [VOL +],
and [SALSA] simultaneously.

turned off, the message “LD OFF” is displayed.

[CHANGE-OVER THE AM TUNING INTERVAL]

The AM tuning interval can be changed over 9 kHz or 10 kHz.

Procedure:

1. Press the [POWER] button to turn the power on.

2. Press the [RADIO/BAND] button to select TUNER (AM)
function.

3. Select the AM BAND mode and press the [DSPL/ENT] button
for an extended time in the AM BAND state.

4. Then, press the [AUTO PRESET/RADIO/BAND] for an ex­tended time.

5. Next, press the [PRESET +] [PRESET –] button select either
9k/10k.

6. Finally, press the [DSPL/ENT] button to set the selected step.

MECHANICAL ADJUSTMENTS

Precaution

1. Clean the following parts with a denatured alcohol-moistened
swab:

record/playback heads pinch rollers
erase head rubber belts
capstan idlers

2. Demagnetize the record/playback head with a head demag­netizer. (Do not bring the head magnetizer close to the erase
head.)

3. Do not use a magnetized screwdriver for the adjustments.

4. After the adjustments, appiy suitable locking compound to the
parts adjusted.

5. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
