The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power
receptacle, when servicing this chassis. To prevent electric shock, do not remove cover. No user- serviceable
parts inside. Refer servicing to qualified service personnel.
Maintenance and repair of this receiver should be done by qualified
service
SERVICING OF HIGH VOLTAGE SYSTEM AND
PICTURE TUBE
When servicing the high voltage system, remove static charge from it
by connecting a 1 Ok ohm Resistor in series with an insulated wire (such
as a test probe) between picture tube dag and
cord ahould be disconnected from AC outlet.)
1. Picture tube in this receiver employs integral implosion protection.
2.
3. Do not lift picture tube by the neck.
4. Handle the picture tube only when wearing shatterproof goggles and after dis-
X-RAY
This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions or servicing many produce 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
2. To keep the set in a normal operation, be sure to make it function on 30.5 +1.5kV
3. Do not substitute a picture tube with unauthorized types and/or brands which

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 device such as non-metallic control knobs, insulating
fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor- capacity networks, mechanical insulators etc.
