SAFETY PRECAUTIONS

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in

the Schematic Diagram and Replacement Parts List.

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

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

Do not modify the original design without permission of manufacturer.

General Guidance

An lsolation Transformer should always be used during

the servicing of a receiver whose chassis is not isolated from

the AC power line. Use a transformer of adequate power rating

as this protects the technician from accidents resulting in

personal injury from electrical shocks.

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

damaged by accidental shorts of the circuitary that may be

inadvertently introduced during the service operation.

If any fuse (or Fusible Resistor) in this monitor is blown, replace

it with the specified.

When replacing a high wattage resistor (Oxide Metal Film

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

Keep wires away from high voltage or high temperature parts.

Due to high vacuum and large surface area of picture tube,

extreme care should be used in handling the Picture Tube.

Do not lift the Picture tube by it's Neck.

Leakage Current Cold Check(Antenna Cold Check)

With the instrument AC plug removed from AC source,

connect an electrical jumper across the two AC plug prongs.

Place the AC switch in the on positioin, connect one lead of

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.

If 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 infinite.

An other abnormality exists that must be corrected before the

receiver is returned to the customer.

Leakage Current Hot 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 for each esposed metallic part. Any

voltage measured must not exceed 0.75 volt RMS which is

corresponds to 0.5mA.

In case any measurement is out of the limits sepcified, there is

possibility of shock hazard and the set must be checked and

repaired before it is returned to the customer.
