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.

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
