IMPOTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by
qualified service peronnel only.
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.
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 discharging 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 many pro-
duce potentially hazardous radiation with prolonged exposure at close
range, the following precautions should be observed:
1. When repairing the circuit, be sure not to increase the high voltage
to more than 34.0 kV (at beam 0µA) for the set.
2. To keep the set in a normal operation, be sure to make it function
on 30.0 ± 1.5kV (at beam 1.8 mA) in the case of the set. The set has
been factory-Adjusted to the above mentioned high voltage.
If there is a possibility that the high voltage fluctuates as a result of
repairs, never forget to check for such high voltage after the work.
3. Do not substitute a picture tube with unauthorized types and/or
brands which may cause excess X-Ray radiation.
BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety
checks.
1. Inspect all lead dress to make certain that the leads are not pinched
or that hardware is not lodged between the chassis and other metal
parts in the receiver.
2. Inspect all protective devices such as non-metallic control knobs,
insulating fishpapers, cabinet backs, adjustment and compartment
covers or shields, isolation resistor- capacity networks, mechani-
cal insulators etc.
