Safety Instructions, Warnings and Notes

GB 5F21RE 2.

2.1 Safety Instructions

Safety regulat ions require that

• Connect the Receiver box to the mains via an isolation

transformer.

• When you use the Receiver box in combination with a

plasma monitor, do not operate the monitor without the front glass plate. One function of this glass plate is to absorb IR radiation. Without this glass plate, the level of radiation could damage your eyes.

• Replace safety component s, indicatedby the symbol

only by components identical to the original ones.

Safety regulations require that returned in its original condition. Pay, in particular, attention to the following points:

• Route the wire trees 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 (only for sets which have a mains isolated power supply): – Unplug the mains cord and connect a wire between

the two pins of the mains plug;

– Set t he mains switch to the 'on' position (keep the

mains cord unplugged!);

– Measure the resistance value between the pins of

themainsplug and the metal shielding of the tuner or the aerial connection on the set. The r eading should be be tween 4.5 M

– Switch‘off’ the set, and remove the wire between the

two pins of the mains plug.

• Check the cabinet for defects, to avoid touching of any

inner parts by the customer.

during

a repair:

after

a repair, the set must be



• Where necessary, measure the oscillograms and direct voltages with ( Measure the voltages in the powersupply section both in normal operation ( are indicated by means of the appropriate symbols.

• The semiconductors indicated in the circuit diagram and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

) and without () aerial signal.



) and in standby (). These values

2.2 Warnings

• All ICs and many other semiconductors are susceptible to electrost a tic discharges (ESD during repa ir can reduce life drastically. Make sure that, during repair, you are connec ted with the same potential as the mass of the set by a wristband with res istance. Keep components and tools also 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.

• Never replace modules or other components while the unit is switched ‘on’.

• When you align the set, use plastic rat her than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

2.3 Notes

• Measure the direct voltages andoscillogramswithregard to the chassis ground ( called.

• The direct voltages and oscillograms shown in the diagrams are indicat ive. Measure them in the Service Default Mode (see chapter 5) with a color bar signal and stereosound(L:3kHz,R:1 kHz unless stated otherwise) and picture carrier at 475.25 MHz (PAL) or 61.25 MHz (NTSC).
