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 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" .
