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:
