Safety Advice

The X-radiation developing in the sets conforms to the X-radiationRegulations (January 8, 1987), issued by the Physikalisch-TechnischeBundesanstalt (federal physiotechnical institution).The high tension for the picture tube and thus the developing X-radiation depends on the precise adjustment of the +A power supply.After every repair of the power supply unit or the horizontal deflectionstage it is imperative that the EHT for the picture tube is checked andre-adjusted if necessary.To avoid consequential damages to the chassis or the picture tubethe integrated protective circuits are allowed to be put out of operationonly for a short time.When replacing the picture tube use only the types specified in thespare parts lists.

General Section

The regulations and safety instructions shall be valid as providedby the "Safety" Service Manual, part number 72010-800.00, aswell as the respective national deviations.

At the rear of the TV receiver are 2 sets of cinch sockets for video/audio in/out, seepage 6.

Similarly in Video Cassette Recorders, sockets are provided for 'Video in' and'Audio in'.

Interconnecting Cables between VCR & TV set are commercially available asaccessories. VCR manual should be referred to ensure that appropriate connectorsare used.

For recording, connect• 'Video out' from TV Receiver to 'Video in' of VCR/VCP.• 'Audio out' from TV Receiver to 'Audio in' of VCR/VCP.

Select the program you wish to record with (P+) or (P-) button.Start the VCR/VCP and operate in the recording mode as described in the operatingmanual for your VCR/VCP.

PLAYBACK IN AV MODE

For VCR and VCP

For play back interconnect as follows :• 'Video in' socket 9 from Receiver to 'Video out' of VCR/VCP.• 'Audio in' socket 10 from Receiver to 'Audio out' of VCR/VCP.

Press and hold button (P+) or (P-) or (AV) directly till display of 'AV' appears on theupper left hand corner of the TV screen. Start the VCR and operate it in the playback mode as described in the operating manual for VCR.

PLAYBACK IN RF MODE

Alignments

All alignment controls not mentioned in this description are preset at the factory and must not be re-aligned in the case of repairs.

Measuring instruments: Oscilloscope with 10:1 test probe, high-resistance voltmeter, colour bar test pattern.

Cecks and alignments after replacement or repair of :Power Supply: Power voltages must be checked after every repair and before every alignment.

Alignment Procedure

Set control VR901 to 124V ± 0.2V

With the control SG on DS-transformer set the voltageto 110V (14") or 150V (20"/21")

With the focus control FOC on DS-transformer align thehorizontal lines for maximum sharpness

Align picture-overscan to 2-3mm with L801

Align picture to vertical middle position with VR703

Align linearity with VR701 and amplitude to 2-3mm over-scan with VR702

Align test pattern to middle position with VR202

With VR201 align voltage at IC201-(47) to maximum,approx. 4.5V, and then reduce it by approx. 0.5V

With L203 align voltage to 2V

Re-connect contact 1 to tuner after alignment

With L202 align to minimum

Set the controls VG (VR601) and VB (VR602) so that nodiscolouration is visible in the grey scale
