SAFETY PRECAUTIONS

Many electrical and mechanical parts in this chassis have special sa ety-related characteristics. These parts are identi ied by in

the Schematic Diagram and Exploded View.

It is essential that these special sa ety parts should be replaced with the same components as recommended in this manual to

prevent X-RADIATION, Shock, Fire, or other Hazards.

Do not modi y the original design without permission o manu acturer.

General Guidance

An isolation Transformer should always be used during the

servicing o a receiver whose chassis is not isolated rom the AC

power line. Use a trans ormer o adequate power rating as this

protects the technician rom accidents resulting in personal injury

rom electrical shocks.

It will also protect the receiver and it's components rom being

damaged by accidental shorts o the circuitry that may be

inadvertently introduced during the service operation.

I any use (or Fusible Resistor) in this monitor is blown, replace it

with the speci ied.

When replacing a high wattage resistor (Oxide Metal Film

Resistor, over 1W), keep the resistor 10mm away rom PCB.

Keep wires away rom high voltage or high temperature parts.

Due to high vacuum and large sur ace area o picture tube,

extreme care should be used in handling the Picture Tube.

Do not li t the Picture tube by it's Neck.

Leakage Current Cold Check(Antenna Cold Check)

With the instrument AC plug removed rom AC source, connect

an electrical jumper across the two AC plug prongs. Place the

AC switch in the on position, connect one lead o ohm-meter to

the AC plug prongs tied together and touch other ohm-meter

lead in turn to each exposed metallic parts such as antenna

terminals, phone jacks, etc.

I the exposed metallic part has a return path to the chassis, the

measured resistance should be between 1MΩ and 5.2MΩ.

When the exposed metal has no return path to the chassis the

reading must be in inite.

An other abnormality exists that must be corrected be ore the

receiver is returned to the customer.

Leakage Current ot Check (See below Figure)

Plug the AC cord directly into the AC outlet.

Do not use a line Isolation Transformer during this check.

Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor

between a known good earth ground (Water Pipe, Conduit, etc.)

and the exposed metallic parts.

Measure the AC voltage across the resistor using AC voltmeter

with 1000 ohms/volt or more sensitivity.

Reverse plug the AC cord into the AC outlet and repeat AC

voltage measurements or each exposed metallic part. Any

voltage measured must not exceed 0.75 volt RMS which is

corresponds to 0.5mA.

In case any measurement is out o the limits speci ied, there is

possibility o shock hazard and the set must be checked and

repaired be ore it is returned to the customer.
