IMPORTANT SAFETY PRECAUTIONS

1. Before returning an instrument to the customer, always make a safety check of the entire instrument, including the
following items, but not limited to them.

a. Be sure that no built-in protective devices are defective and/or have been defeated during servicing. (1) Protective

shields are provided on this chassis to protect both the technician and the customer. Correctly replace all missing
protective shields, including any removed for servicing convenience. (2) When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in place all protective devices, including, but not limited to, non-metallic
control knobs, insulating fishpapers, adjustment and compartment covers/shields, and isolation resistor/capacitor
networks. Do not operate this instrument or permit it to be operated without all protective devices correctly

installed and functioning.

b. Be sure that there are no cabinet openings through which an adult or child might be able to insert their fingers and

contact a hazardous voltage. Such opening include, but are not limited to (1) spacing between the picture tube and
the cabinet mask, (2) excessively wide cabinet ventilation slots, and (3) an improperly fitted and/or incorrectly
secured cabinet back cover.

c. Leakage Current Hot Check: With the instrument completely reassembled, plug the AC line cord directly into a 230V

AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system.
With the instrument AC, first switch ON and then OFF. Measure from a known earth ground (metal waterpipe,
conduit, etc.) to all exposed metal parts of the instrument (antennas, handle bracket, metal cabinet, screwheads,
metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the
chassis. Any current measured must not exceed 3.5 mA. Reverse the instrument power cord plug in the outlet and
repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL

SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUMENT TO THE
CUSTOMER.

2. Read and comply with all caution and safety-related notes on or inside the Monitor cabinet, on the Projection Monitor

chassis or on the picture tube.

3. Design Alteration Warning: Do not alter or add to the mechanical or electrical design of this unit. Design alterations and
additions, including, but not limited to, circuit modifications and the addition of the items such as auxiliary audio and/or
video output connections might alter the safety characteristics of this Projection Monitor and create a hazard to the user.
Any design alterations or additions will void the manufacturer's warranty and will make you, the service, responsible for
personal injury or property damage resulting therefrom.

4. Hot Chassis Warning:

a. Some Monitor chassis are electrically connected directly to one conductor of the AC power cord and may be safely

serviced without an isolation transformer only if the AC power plug is inserted so that the chassis is connected to the
ground side of the AC power source. To confirm that the AC power plug is inserted correctly, with an AC voltmeter
measure between the chassis and a known earth ground. If a voltage reading in excess of 1.0V is obtained, remove
and reinsert the AC power plug in opposite polarity and again measure the voltage potential between the chassis
and a known earth ground.

b. Some Monitor chassis normally have 85V AC (RMS.), between chassis and earth ground regardless of the AC plug

polarity. These chassis can be safely serviced only with an isolation transformer inserted in the power line between
the receiver and the AC power source, for both personnel and test equipment protection.

c. Some Projection Monitor chassis have a secondary ground system in addition to the main chassis ground. This

secondary ground system is not isolated from the AC power line. Insulating material that must not be defeated or
altered electrically separates the two ground systems.

5. Observe original lead dress. Take extra care to assure correct lead dress in the following areas:

a. near sharp edges,
b. near thermally hot parts (be sure that leads and components do not touch thermally hot parts),
c. the AC supply,
d. high voltage,
e. antenna wiring. Always inspect in all areas for pinched, out-of-place, or frayed wiring. Do not change spacing

between components and between components and the printed-circuit board. Check AC powers cord for damage.

6. Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with
components, parts, or wiring that meet original specifications. Additionally, determine the cause of overheating and/or
damage and, if necessary, take corrective action to remove any potential safety hazard.

7. PRODUCT SAFETY NOTICE: Many Monitor electrical and mechanical parts have special safety-related characteristics
some of which are often not evident from visual inspection, nor can the protection they give necessarily be obtained by
replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are
identified in this service data by shading with a mark on schematics. Use of a substitute replacement part that does not
have the same safety characteristics as the recommended replacement part in this service data parts list might create
shock, fire, and/or other hazards.
