IMPORTANT SERVICE NOTES
and repair of this receiver should be done by
Maintenance
qualified service personnel only.
SERVICING OF HIGH VOLTAGE SYSTEM AND
PICTURE TUBE
When servicing the high voltage system, remove static charge from it by
connecting a 10 k 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.)
the high voltage completely.
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
hazardous radiation with prolonged exposure at close range, the following
precautions should be observed:
When repairing the circuit, be sure not to increase the high voltage to more
than 25.3 kV, (at beam 0 ,A) for the set.
than 29.3 kV, (at beam 0 4) for the set.
been factory -Adjusted to the above-mentioned high voltage.
factory -Adjusted to the above-mentioned high voltage.
forget to check for such high voltage after the work.
not substitute a picture tube with unauthorized types and/or brands which may cause
O
excess X-ray radiation.
BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety
checks.
lodged between the chassis and other metal parts in the receiver.
cabinet backs, adjustment and compartment covers or shields, isolation resistor-
capacity networks, mechanical insulators etc.
be sure to make it function on
