The release method of a CD disc tray LOCK function
There is a disc lock function for the disc theft prevention for a
demonstration at a shop front in this machine.
Procedue:
1. Press the ?/1 button to turn the set on.
2. Press two buttons of xand Z(EJECT) simultaneously for
five seconds.
3. The message “LOCKED” is displayed and the tray is locked.
(Even if exiting from this mode, the tray is still locked.)
4. Press two buttons of xand Z(EJECT) simultaneously for
five seconds again.
5. The message “UNLOCKED” is displayed and the tray is
unlocked.
6. To exit from this mode, press the ?/1 button to turn the set
off.
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
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.
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 pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
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 flexible board is easily damaged and should be handled with
care.

•If error occurred, the display remains like “TAPE BAG-2”.
4. Exiting from the aging mode
•Be sure to perform Cold Reset to exit from the aging mode.
[Change-over of AM Tuner Step between 9 kHz and
10 kHz]
•Astep of AM channels can be changed over between 9 kHz and
10 kHz.
Procedure:
1. Press ?/1button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND
button to select the BAND “AM”.
3. Press ?/1button to turn the set OFF.
4. Press TUNER/BAND and ?/1buttons simultaneously, and
the display of fluorescent indicator tube changes to “AM 9 k
STEP” or “AM 10 k STEP”, and thus the channel step is changed
over.
[Cold Reset]
•The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.
Procedure:
1. Press three buttons x, PLAY MODE/TUNING MODE ,
and DISC1 simultaneously.
2. The fluorescent indicator tube displays “COLD RESET” and
the set is reset.
[Aging Mode]
This mode can be used for operation check of CD section and tape
deck section.
•If an error occurred:
The aging operation stops and is displayed status.
•If no error occurs:
The aging operation continues repeatedly.
