SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power
cord is less than 460 kohms, the unit is defective.
LASER RADIATION
Do not stare into beam or view directly with optical instruments, class 3A laser product.

DIAGNOSTICS OF OPTICAL PICKUP
AND REPLACING TRAVERSE UNIT
Make failure diagnostics of the Optical Pickup as follows.
If the laser drive current (Iop) becomes more than 1.5 times of
the initial value, the Optical Pickup should be replaced.
The laser drive current initial value is checked by "Iop checked
Method" of next page.
In case of replacing the Pickup, change the whole part of the
Traverse Unit.
No mechanical adjustment is necessary after the replace-
ment.

Select the laser ON/OFF (CD/DVD) mode of the test mode,
and check the lop value of DVD laser or CD laser.
(See page 21 for test mode.)
1.1. DVD laser current check
(1) Press the SKIP or button to display the la-
ser current value, and then select T22.
(2) Press the PLAY button and check the current value of
Iop (nnnn).

2. Note for Handling the Laser Pick-Up
The protection for the damage of laser diode.
If you want to change the optical device unit from any other
units, you must keep the following.
(1) It should be done at the desk already took measures the
static electricity in care of removing the OPU's (Optical
device unit) connector cable.
(2) Workers should be put on the "Earth Band".
(3) It should be done to add the solder to the short land to
prevent the broken Laser diode before removing the 24P
FFC cable.
(4) Don't touch OPU's connector parts carelessly.
3. Replacement of the Laser Pick-up
(Traverse Unit)
Check the Iop (Laser drive current)
If the present Iop (current) value exceeds.+150% of the ini-
tial value, replace the Traverse unit (Laser Pick-up) with a
new one.

4. Rewriting the default value of the laser
current
To rewrite the default value of the laser current, press the
button for at least 5 seconds while the CD or DVD laser
current is displayed, then press the or button
to select T23. (For details, see "Iop checked Method" on
page 22.)
If the button is pressed while T23 is displayed, the cur-
rent value is displayed at "mmmm" and stored in the EE-
PROM.
5. Resetting the accumulated laser on time
To clear the accumulated laser on time, press the button
while the accumulated laser on time is displayed (TB1, TB2

pears at the fourth position, then press the or
button to select TB3.
If the button is pressed while TB3 is displayed, the ac-
cumulated laser on time of CD and DVD is cleared.
When TB1 or TB2 is selected with the or but-
ton, "nnnnnnn" is displayed as 0 so you can check.
