Safety instruction, Warnin

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

: InGaAIP (DVD)

: AIGaAs (CD)

Wavelength : 658nm (DVD)

: 783nm (CD)

Power out objective lens: 1.0mW (DVD read)

: 1.2mW (CD read)

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.

A

1-4

Warning

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:
