TURE 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 the same type number of picture tube for continued safet
y.
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 completel
y.
X-RA
Y
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 followin precautions should be observed:
1.
When repairing the circuit, please make sure do not increase the high voltage of the set to more than 34.0kV (at beam 0
µ
A).
2.
T
o
keep the set in a normal operation , please make sure it's function at 30.0kV
±
1.5kV
(at beam 1,700
µ
A). 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 the repaires, never forget to che
ck for such high voltage after the work.
3.
Do not substitute a picture tube with unauthorizerd
types and/or brands which may
cause excessive 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 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-metal control knobs, insulating fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor- ca- pacity networks, mechanical insulators etc.
