IMPORTANT SAFETY PRECAUTIONS VER1.0
1-1
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, nonmetallic control knobs, insulating fish papers, 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.
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 120V 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 Institutes (ANSI) C101.1 Leakage Current
for Appliances and Underwriters Laboratories (UL) 478. With the instrument AC switch first in the ON position
and then in the OFF position, measure from a known earth ground (metal water pipe, conduit, etc.) to all
exposed metal parts of the instrument (antennas, handle bracket, metal cabinet, screw heads, 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 milliamp. 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.
