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.

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 shold 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.
Replacement of the Traverse Unit
When repairing, carry out failure diagnostics by following the procedure described below.
If the present value of the laser drive current is 50% up to initial value, it is the point of the pickup replacement.
In case of the pickup replacement, replace the Traverse Unit with no adjustment.
The initial value is indicated on the label on back side of Mecha.
NO DISC indicated, Playback not smooth, etc.
Laser drive current check
HF signal check
Traverse Unit replacement (refer to page 8)
Present value: 50% up to initial value
Laser drive current check after replacement.
If the present value is less than 80mA, write on
the new label by hand, put on the new label over
the old label.
If the present value exceeds 80mA,
replace the Traverse Unit with a new one.
Cause: Damaged electrostatically when replaced.

Service Mode
1. Aging Mode
(1) Preparation
(a) Equipment used: Any one of DVD Karaoke Disc (containing more than 10 titles), CD/Video CD (Ver1.0: None
playback control), or No-menu DVD. (Setting varies according to the disc used.)
(b) Unit setting: No spec other than the following procedure (Aging mode)
At the tray open status, press the "POWER" button to turn on the power while pressing the "PLAY" and
"OPEN/CLOSE" buttons for DVD operation simultaneously. mark on the FL lights, and the unit is set to the heat
run mode.
(2) Procedure
(a) According the above, set to the aging mode.
(b) Set a DVD Karaoke disc to the tray and press the "PLAY" button once. mark on the FL blinks, and aging peration
(after playback title-1 and title-10 of the disc, the tray open/close is made automatically, then playback the title-1
again) starts. This aging operation continues automatically until it is stopped or it stops caused by an error.
(c) When using other than a DVD Karaoke disc, aging operation (after playback all titles of the disc, the tray open/close
is made automatically, then playback all titles again) starts by pressing the "PLAY" button once, and mark on
the FL lights. The aging operation continues automatically until it is stopped or it stops caused by an error. In case
of some error in DVD, the tray opens and the following error messages are displayed on the FL.
2. Initial Setting Mode
(1) Preparation
(a) Equipment used: None
(b) Unit setting: No spec other than the following procedure
(2) Procedure
(a) Initialize the DVD player when µcom, peripheral parts of µcom, or Main P.W.B. has been replaced in servicing.
(b) Carry out the following to restore factory setting mode. At the player stop condition, press 3 buttons for DVD peration
("PLAY", "OPEN/CLOSE", and " SKIP") until "INITIALIZE" appears and disappears in the FL.
("Initialized" appears and disappears on the TV screen.)
(c) All user setting will be lost and its factory setting will be restored when this initialization is made. Be sure to
memorize your setting for restoring again after the initialization.
