Safety Instructions
1.1
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)
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
mounted cable clamps.
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 to the ‘on’ position (keep the
mains cord unplugged!).
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
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.

Warnings
2.1
General
All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD,
). Careless handling
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:
–
Complete kit ESD3 (small tablemat, wristband,
4822 310 10671.
–
Wristband tester 4822 344 13999.
Be careful during measurements in the live voltage
section. The primary side of the power supply, including
the heatsink, 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 ‘lightning 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’.

Only quali ed service personnel may remove the cover or
attempt to service this device, due to possible eye injury.
Repair handling should take place as much as possible
