IMPORTANT SERVICE NOTES

Maintenance and repair of this receiver should be done by

SERVICING OF HIGH VOLTAGE SYSTEM AND

PICTURE TUBE

When servicing the high voltage system, remove static charge from it by

connecting a 10k ohm Resistor in series with an insulated wire (such as a

test probe) between picture tube dag and 2nd anode lead. (AC line cord

should be disconnected from AC outlet.)

1. Picture tube in this receiver employs integral implosion protection.

discharging the high voltage completely

2. Replace with tube of the same type number for continued safety.

3. Do not lift picture tube by the neck.

4. Handle the picture tube only when wearing shatterproof goggles and after

X-RAY

This receiver is designed so that any X-Ray radiation is kept to an absolute

minimum. Since certain malfunctions or servicing may produce potentially

than 28.0 kV (at beam 0

hazardous radiation with prolonged exposure at close range, the following

precautions should be observed:
