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.
s LASER RADIATION
Caution - Class 1M visible and invisible laser radiation when open.
Do not view directly with optical instruments.

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.
Laser drive current initial value:

1. Iop checked Method
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 16 for test mode.)
1.1. DVD laser current check
(1) Press the or button to display the laser
current value, and then select "T24".
(2) Check the current value of Iop (nnnn).
( : Off, DVD laser, Initial value: Current value: nn.nn [mA])
1.2. CD Laser current check
(1) Press the or button to display the laser
current value, and then select "T22".
(2) Check the current value of Iop (nnnn).
( : Off, CD laser, Initial value: Current value: nn.nn [mA])
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 oth-
er 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 (Op-
tical 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
initial value, replace the Traverse unit (Laser Pick-up) with
a new one.

(2) Press the button for at least 5 seconds, and
"SAVE?" is displayed.
(3) Press the or button to select the "T23".
(4) Press the button and store the current value
"T23". After "OK?" is displayed, stored value "T23" is
displayed.
(5) Press the button to display the current value
"T24" without storing the current value "T23".
4.2. Store the current value of the laser current
: CD
(1) Current value "T22" is selected.
(2) Press the button for at least 5 seconds, and
"SAVE?" is displayed.
(3) Press the or button to select the "T21".

time
To clear the accumulated laser on time, press the
button while the accumulated laser on time is displayed
(TB1, TB2 : For details, see "Test Mode" on page 13.) until
" CLR?" appears at the "nnnnn" position, then press the
or button to select TB3.

HOW TO REPLACE TRAVERSE UNIT
Caution: The optical pickup can be damaged easily
by static electricity charged on human
body. Take necessary anti-static measures
when repairing around the optical pickup.
(Follow the procedure below in reverse order when
reassembling.)
1. Top plate disassembly
(1) Remove 6 screws, then detach Top Plate.
2. Tray disassembly
(1) Insert the stick made from the stainless steel of 2.5
(or thing of equivalent hardness) from the hole of the
Mecha Unit left side.
(2) Check that the stick has touched the side of SLIDE
CAM, from the hole at the left on the Tray. And push in
SLAIDE CAM slowly securely. Don't push the projec-
tion which has attached Spring at this time. (Spring
may be warped)
SLIDE CAM side
