Cleaning the Cabinet
¦
Use a soft cloth slightly moistened with a mild
detergent solution. Do not use a solution
containing alcohol, spirits, ammonia or abrasives.
Cleaning Discs
¦
When a disc becomes dirty, clean it with a
cleaning cloth.Wipe the disc from the centre
out. Do not wipe in a circular motion.
¦
Do not use solvents such as benzine, thinner,
commercially available cleaners, or antistatic
spray intended for analogue records.
Maintenance
Cleaning the disc lens
¦
After prolonged use, dirt or dust may
accumulate at the disc lens.To ensure good
playback quality, clean the disc lens with Philips
CD Lens Cleaner or any commercially available
cleaner. Follow the instructions supplied with the
cleaner.

Safety Instructions, Warnings and Notes
2. Safety Instructions, Warnings and Notes
2.1 Safety Instructions
2.1.1 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) 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 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
measurement is less than 1 MΩ.
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.
2.1.2 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).
2.2 Warnings
2.2.1 General
• All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD, symbol ). 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,
connection box, extension cable and earth cable) 4822
310 10671.
– 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 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’.
2.2.2 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 handling 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:
