1. Check the area of your repair for unsoldered or poorly-soldered
connections. Checktheentire board surfacefor solder splashes
and bridges.
2. Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
4. Look for parts which, through functioning,show obvious signs
of deterioration. Point them out to the customer and
recommend their replacement.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety
checks before releasing the set to the customer.
5. Check the B+ voltage to see it is at the values specified.
6. Flexible Circuit Board Repairing
•Keep the temperature of the 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.

This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
The following caution label is located inside the 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.
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 chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

Step 3: Setting the time
You must set the time before using the timer
functions.
The clock is on a 24-hour system for the European
model, and on a 12-hour system for other models.
For illustration purposes, the 24-hour system
model is used.
1Press MODE SELECT when the system
is turned off.
“Clock Set ?”appears.
When the system is in the Power Saving
Mode, “Clock Set ?”will not appear. Either
set Power Saving Mode off, or follow the
steps on the following page (“To change the
time”) after turning the power on.
2Press PUSH ENTER.
The hour indication flashes.
3Move the multi stick toward vor V
repeatedly to set the hour.
4Move the multi stick toward B.
The minute indication flashes.
5Move the multi stick toward vor V
repeatedly to set the minute.
6Press PUSH ENTER.
To cancel the menu operation
Press MODE SELECT.
Tips
•Refer to the illustration to use the multi stick. Place
your finger on the center of the multi stick and
move in the direction you want (up/down or left/
right shown v/V or b/B in this manual).
PUSH
ENTER
•If you’ve made a mistake, start over from step 1.

To change the time
The previous explanation shows you how to set
the time while the power is off. To change the
time while the power is on, do the following:
1Press MODE SELECT repeatedly to select “Set
Up Mode”, then press PUSH ENTER.
2Move the multi stick toward bor Brepeatedly
to select “Timer Set Up ?”, then press PUSH
ENTER.
3Move the multi stick toward bor Brepeatedly
to select “Clock Set ?”, then press PUSH
ENTER.
4Perform steps 3 through 6 on page 9.
Note
The clock settings are canceled when you disconnect
the power cord or if a power failure occurs.
