IMPORTANT

SERVICE

NOTES

Maintenance and repair of this

reoeiver

should be done by

qualified service personnel only.

SERVICING OF HIGH VOLTAGE SYSTEM AND

PICTURE TUBE

When servicing the high voltage system, remove static

charge from it by

co~ecting

a

1Ok

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 continu-

ed safety.

3. Do not lift picture tube by the neck.

4. Handle the picture tube only when wearing shatter-proof

goggles and after discharging the high voltage

corn-

pletely.

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 dose range, the following pre-

cautions should be observed:

1. When repairing the circuit, be sure not to increase the

high

voltage

to

more

than

27kV,

(at

beam

1000pA)

for

the

set.

2.

To

keep

the

set

in

a

normal

operation,

be

sure

to

make

it

function

on

23.5

kV

+

1SkV

(at

beam

1OOOpA)

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 the 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 muse 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 leads are not

pinched or that hardware is not lodged between the

dmsis

and other metal parts in the receiver.

2. Inspect all protective devices such as non-metallic con-

trol knobs, insulating fishpapers, cabinet backs, adjust-

ment and compartment covers or shields, isolation

resistorcapacity networks, mechanical insulators etc.
