Safety Precaution
WARNING
Service should not be attempted by anyone unfamiliar with the necessary precautions on this
monitor.
The followings are the necessary precautions to be observed before servicing.
1. Always discharge the high voltage to the CRT conductive coating before handling the CRT.
The picture tube is highly evacuated and if broken, glass fragments will be violently
exploded. Use shatter proof goggles and keep picture tube away from the bare body while
handling.
2. When replacing a chassis in the cabinet, always be certain that all the protective devices are
put back in place, such as nonmetallic control knobs, insulating covers, shields, isolation
resistor capacitor network etc.
3. Before returning the monitor to the customer, always perform an AC leakage current check
on the exposed metallic parts of the cabinet, such as signal connectors, terminals, screw
heads, metal overlays, control shafts etc, to be sure the monitor is safe to operate without
danger of electrical shock. Plug the AC line cord directly into a AC outlet (do not use a line
isolation trasformer during this check.). Use an AC voltmeter having 1500 ohm per volt or
more sensitivity in the following manner : Connect ground(water pipe, conduit, etc.) and
the exposed metallic parts, one at a time. Measure the AC Voltage across the combination
of 1500 ohm resistor and 0.15 capacitor. Reverse the AC plug at the AC outlet and
repeat AC voltage measurements for each exposed metallic part. The Voltage must not
exceed 0.3 volts RMS. This corresponds to 0.2 milliamp AC. Any value exceeded this limit
constitutes a potential shock hazard and must be corrected immediately.

INSTRUCTIONS TO USER
This equipment generates and uses radio frequency energy and if not installed and used
properly, that is, in strict accordance with the manufacturer's instruction, may cause
interference to radio and television. It has been tested and found to comply with the limits for
the specifications in Subpart J of Part 15 FCC Rules, which are designed to provide reasonable
protection against such interference in a residential installation. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of th |
