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 is registered on the seal attached to the
rear of the Mecha.Unit.
In case of replacing the Pickup, change the whole part of the
Traverse Unit.
No mechanical adjustment is necessary after the replace-
ment.
Example: DVD 30mA
CD 30mA
Disc no read, unsteady playback, etc.
Laser drive current (Iop) check
HF wave form check
(Refer to WAVE FORMS)
Present value exceeds the ini-
tial value by 1.5 times
Traverse Unit replacing
(See page 6, 7 for details)
Laser current registering after replacement.
Step: Disc playback
Write the measured value on the seal attached to the
Mecha. Unit
* As to the measuring method, refer to page 9, 10.

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. Iop Measurement Method
When measuring Laser drive current (Iop), playback the
discs (CD,DVD) described below, measure Iop for CD Laser
and DVD Laser by the test point (+5V-A2~ LD (CD), LD
(DVD))on the Main P.W.B.
Test Disc : DVD/DVDT-S01 or commercially available
discs.
: CD/TCD-784 (manufactured by ALMEDIO
INC) or commercially available discs.

then release the FUNCTION and OPEN/CLOSE
( ) buttons.
(4) After about 3 seconds, "INITIALIZE" appears on the
display.
(5) After initialization is complete (when "INITIALIZE"
turns off), the function is set to "DVD" and the vol-
ume level is set to ("-dB" is displayed).
2. System check mode
Use this to display the version information, etc.

and A.FWD ( ) buttons on the main unit, press
the ON/STANDBY button.
(2) Press the STATUS button on the remote control
unit (RC-1005 or RC-1006) to display the following
information, in this order: Time (TIME) System
