Safety instructions
1. General safety
Safety regulations require that during a repair:
. Connect the unit to the mains via an isolation transformer.
. Replace safety components indicated by the symbol ,
only by components identical to the original ones. Any other
component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, you must return
the unit in its original condition. Pay, in particular, attention to
the following points:
. Route the wires/cables correctly, and fix them with the
mounted cable clamps.
. Check the insulation of the mains lead for external
damage.
. Check the electrical DC resistance between the mains plug
and the secondary side:
1) Unplug the mains cord, and connect a wire between
the two pins of the mains plug.
2) Set the mains switch the “on” position (keep the
mains cord unplug).
3) Measure the resistance value between the mains
plug and the front panel, controls, and chassis
bottom.
4) Repair or correct unit when the resistance
measurement is less than 1M .
5) Verify this, before you return the unit to the
customer/user (ref. UL-standard no. 1492).
6) Switch the unit “off”, and remove the wire between
the two pins of the mains plug.
2.Laser safety
This unit employs a laser. Only qualified service personnel
may remove the cover, or attempt to service this device (due
to possible eye injury).
Laser device unit
Type : Semiconductor laser GaAlAs
Wavelength : 650nm (DVD)
: 780nm (VCD/CD)
Output power : 7mW (DVD)
:10mW(DVD/CD)
Beam divergence: 60 degree
Note: Use of controls or adjustments or performance of
procedure other than those specified herein, may result in
hazardous radiation exposure. Avoid direct exposure to
beam.

Warnings
1.General
. All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD). Careless handing during
repair can reduce life drastically. Make sure that, during
repair, you are at the same potential as the mass of the set
by a wristband with resistance. Keep components and tools
at this same potential. Available ESD protection equipment:
1) Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
2) Wristband tester 4822 344 13999.
. Be careful during measurements in the live voltage section.
The primary side of the power supply , including the heat
sink, carries live mains voltage when you connect the player
to the mains (even when the player is “off”!). It is possible to
touch copper tracks and/or components in this unshielded
primary area, when you service the player. Service
personnel must take precautions to prevent touching this
area or components in this area. A “lighting stroke” and a
stripe-marked printing on the printed wiring board, indicate
the primary side of the power supply.
. Never replace modules, or components, while the unit is
“on”.
2. Laser
. The use of optical instruments with this product, will
increase eye hazard.
. Only qualified service personnel may remove the cover or
attempt to service this device, due to possible eye injury.
. Repair handing should take place as much as possible with
a disc loaded inside the player.
. Text below is placed inside the unit, on the laser cover
shield:

CAUTION: VISIBLE AND INVISIBLE LASER RADIATION
WHEN OPEN, AVOID EXPOSURE TO BEAM.

Mechanical and Dismantling Instructions
Dismantling Instruction
The following guidelines show how to dismantle the player.
Step1: Remove 5 screws around the Top Cover. And remove
it (Figure 1)
Step2: If it is necessary to dismantle Loader or Front Panel,
It should be remove the front door assembly first. (Figure 2)
If the trace can’t open in normal way, you can make it by push
the gear wheel manually using the slot below the bottom
chassis with a tool.. (Figure 3)
Note: Make sure to operate gently otherwise the gear wheel
would be damaged.

Step3: Dismantling Loader, First, disconnect the 3 connectors
aiming in the figure, and then remove the 4 screws at both
sides of the loader,(Figure 4)
Step4:Dismantling Front Panel: disconnect the 2 connectors
aiming in the figure then Release the snaps on the both sides
of Front Panel and gently pull the Panel out from the set.

Software upgrade
A. Preparation to upgrade software
1) Start the CD Burning software and create a new CD
project (Data Disc) with the following setting:
Label: DVP5XX
File System: DVP530.BIN
Note: It is required capital letter for the Label name &
the File System name.
2) Burn the data onto a blank CDR
B. Procedure for software upgrade:
1) Power up the set and insert the prepared Upgrade
CDR.
2) The set will starts reading disc & response with the
following display TV screen:
Upgrade File DETECTED
Upgrade?
Press Play TO START
3) Press <Play>button to confirm, then screen will display :
