SAFETY PRECAUTIONS

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by inthe Schematic Diagram and Exploded View. It is essential that these special safety parts should be replaced with the same components as recommended in this manual toprevent X-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

General Guidance

An isolation Transformer should always be used during theservicing of a receiver whose chassis is not isolated from the ACpower line. Use a transformer of adequate power rating as thisprotects the technician from accidents resulting in personal injuryfrom electrical shocks.

It will also protect the receiver and it's components from beingdamaged by accidental shorts of the circuitry that may beinadvertently introduced during the service operation.

If any fuse (or Fusible Resistor) in this monitor is blown, replace itwith the specified.

When replacing a high wattage resistor (Oxide Metal FilmResistor, 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, connectan electrical jumper across the two AC plug prongs. Place theAC switch in the on position, connect one lead of ohm-meter tothe AC plug prongs tied together and touch other ohm-meterlead in turn to each exposed metallic parts such as antennaterminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, themeasured resistance should be between 1M and 5.2M. When the exposed metal has no return path to the chassis thereading must be infinite.An other abnormality exists that must be corrected before thereceiver 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 capacitorbetween a known good earth ground (Water Pipe, Conduit, etc.)and the exposed metallic parts.Measure the AC voltage across the resistor using AC voltmeterwith 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat ACvoltage measurements for each exposed metallic part. Anyvoltage measured must not exceed 0.75 volt RMS which iscorresponds to 0.5mA.In case any measurement is out of the limits specified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.
