SAFETY PRECAUTIONS
Many electrical an mechanical parts in this chassis have special safety-relate characteristics. These parts are i entifie by in
the Schematic Diagram an Explo e View.
It is essential that these special safety parts shoul be replace with the same components as recommen e in this manual to
prevent X-RADIATION, Shock, Fire, or other Hazar s.
Do not mo ify the original esign without permission of manufacturer.
General Guidance
An isolation Transformer should alwa s be used uring the
servicing of a receiver whose chassis is not isolate from the AC
power line. Use a transformer of a equate power rating as this
protects the technician from acci ents resulting in personal injury
from electrical shocks.
It will also protect the receiver an it's components from being
amage by acci ental shorts of the circuitry that may be
ina vertently intro uce uring the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace it
with the specifie .
When replacing a high wattage resistor (Oxi e Metal Film
Resistor, over 1 W), keep the resistor 10 mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum an large surface area of picture tube,
extreme care shoul be use 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 remove from AC source, connect
an electrical jumper across the two AC plug prongs. Place the
AC switch in the on position, connect one lea of ohm-meter to
the AC plug prongs tie together an touch other ohm-meter
lea in turn to each expose metallic parts such as antenna
terminals, phone jacks, etc.
If the expose metallic part has a return path to the chassis, the
measure resistance shoul be between 1 MΩ an 5.2 MΩ.
When the expose metal has no return path to the chassis the
rea ing must be infinite.
An other abnormality exists that must be correcte before the
receiver is returne to the customer.
Leakage Current Hot Check (See below Figure)
Plug the AC cor irectly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5 K/10watt resistor in parallel with a 0.15 uF capacitor
between a known goo earth groun (Water Pipe, Con uit, etc.)
an the expose metallic parts.
Measure the AC voltage across the resistor using AC voltmeter
with 1000 ohms/volt or more sensitivity.
Reverse plug the AC cor into the AC outlet an repeat AC
voltage measurements for each expose metallic part. Any
voltage measure must not excee 0.75 volt RMS which is
correspon s to 0.5 mA.
In case any measurement is out of the limits specifie , there is
possibility of shock hazar an the set must be checke an
repaire before it is returne to the customer.
