1. The unit of resistance «ohm»is omitted (K=1000 ohms.

M= Megaohm).

2. All resistors are 1/16 watt. unless otherwise noted.

3. All capacitors are µF, unless otherwise noted (P= µµF).

4. The capacitor with Part No. RC-FZ9XXXBMNJ is de-

signed to with stand 63V.

5. The capacitor with Part No. RC-FZ4XXXBMNJ is de-

signed to with stand 50V.

Service precaution:

The area enclosed by this line is directly (

connected with AC mains voltage.

When servicing the area, connect an insulating

transformer between TV receiver and AC line to

eliminate hazard of electric shock.

Waveform measurement condition:

Colour bar generator signal of 70 dB from RF input.
