Safety instructions,Warnings,Notes

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 retum

the unit in its original condifion.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 extemal

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 tge mains switch the“on”position (keep the mains

cor d unplug).

3) Measure the resistance value between the mains

plug and the front panel, controls, and chassls

bottom.

4) Reoair or correct unit when the resistance

measurement is less than 1M

5) Ver ify 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).

Warnings

Parker

1.General

.All lCs 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 wristhband 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(pos.1005),including

the heat sink,carries live mains voltage when you connect

the player to the mains(even when the player is“off” lt 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 in jury.

.Repair handing should take place as much as possible with

a disc loaded inside the player

. Te x t below is placed inside the unit, on the laser cover

shield

CAUTION: VISIBLE AND INVISIBLE LASER RADIATION

WHEN OPEN,AVO I D EXPOSURE TO BEAM.
