1. Safety guidelines
Safety Instructions
1. Before returning an instrument to the customer, always make a safety check of the entire instrument, including, but not limited
to, the following items:
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, insulating materials, barriers, 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. Servicers who defeat safety features or fail to perform safety checks may be
liable for any resulting damage.
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 openings include, but are not limited to, (1) excessively wide cabinet ventilation slots, and (2) an
improperly fitted and/or incorrectly secured cover panels.
c) Leakage Current Hot Check. With the instrument completely reassembled, plug the AC line cord directly into a 220 V AC
outlet (Do not use an isolation transformer during this test). Use a leakage current tester or a metering system that complies
with American National Standards Institute (ANSI) C101.0 Leakage Current for Appliances and Underwriters Laboratories
(UL) 1410, (50.7). With the instrument AC switch first in the on position and then in the off position, 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 OR
BEFORE CONNECTING ACCESSORIES.

d) Ultraviolet Radiation exposure - Warning: This lamp can cause serious skin burn and eye inflammation from shortwave
ultraviolet radiation if not operated in enclosed fixtures. DO NOT operate this lamp in a fixture with a missing or broken lens
cover.
e) Ozone: Operating lamp generates ozone gas which is harmful to the respiratory system. Therefore the lamp should be
operated in adequately ventilated equipment.
2. Read and comply with all caution and safety-related notes on or inside the projector cabinet or on the projector chassis, or on
the picture tube.
3. Design Alteration Warning - Do not alter or add to the mechanical or electrical design of this apparatus. Design alterations and
additions, including, but not limited to, circuit modifications and the addition of items such as auxiliary audio and/or video output
connections, might alter the safety characteristics of this apparatus and create a hazard to the user. Any design alterations
or additions may void the manufacturer’s warranty and may make you, the servicer responsible for personal injury or property
damage resulting therefrom.
4. Lamp explosion Protection Warning – The lamp in this projector operates with a high internal pressure and there is a slight risk
that the lamp may explode, particularly if it is used beyond its rated life. Do not remove, install, or otherwise handle the lamp
in any manner without first putting on shatterproof goggles equipped with side shields. People not so equipped must be kept
safely away while lamps are handled. Keep the lamp away from your body. For continued explosion protection, replace the
lamp only with one of the same type number. Always replace the lamp before the rated life time.
