IMPORTANT SAFETY PRECAUTIONS Ver1.0
1. Before return ing an instrument to the customer,
always make a saf ety 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 mis sing protec tive sh ields, including an y removed f or ser vicing con venienc e. (2) W hen reins talling
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 is olation res istor/capacit or 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 ha zardous voltage, Such opening inc lude, but are not lim ited to, (1) spac ing between
the picture tube and the c abinet mask , (2) excessively wide ca binet ventilation sl ots, and (3) an improper ly
fitted and/or incorrectly secured cabinet back cover.
c. Leakage Current Hot Check
—
—With the instr ument completely reas sembled, plug the AC line cord directly
——
into a 120V AC out let . (Do not use an isolatio n tr a nsformer during this tes t.) Us e a l eakage current tester or a
metering system that com plies with American Nati onal Standards Institutes (ANSI) C101.1 Leakage Cur rent
for Appliances and U nderwriters Laboratories ( UL) 47 8 . W ith the ins tr ument AC switch firs t in t he O N pos it io n
and then in the OFF position, m easure 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 sh afts, etc.), especially any exposed m etal parts that offer an electrical return path to th e
chassis. Any cur rent m easured m us t not ex cee d 3.5 m illiam p. Rev erse t he ins tr um ent power cord plu g in the
outlet and repeat test.
ANY MEASUREMENTS NOT WITHIN T HE LIMITS SPECIFIED HEREIN INDIC ATE
A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE
INSTRUMENT TO THE CUSTOMER.

3. Design Alteration Warning
—
—Do not alter or add to the mechanical or electrical design of this unit. Design
——
alterations and additio ns, including , but not limited to, circuit modif ications and th e addition of the item s 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.

IMPORTANT SAFETY PRECAUTIONS Ver1.0
4. Hot Chassis Warning
AC power cord and may be safely serviced without an isolation transformer only if the AC power plug is
inserted so that the c hassis is c onnected to the gr ound side of the AC power so urce. To confirm that the AC
power plug is inserted correctly, with an AC voltm eter measure between the chassis and a known earth
ground. If a voltage read in g in ex c es s of 1.0V is o bta in ed, r emove and reinsert t he AC po wer pl ug i n op pos it e
polarity and again m easure the voltage potent ial between the chass is and a known earth gr ound. b. Some
Monitor chassis norm all y have 85V AC (RMS.) , bet ween c hassis a nd ear th gr oun d regard less of the A C plug
polarity. These chassis can be safely service d only with an isolation transformer inserted in the power line
between the receiv er and the AC power source, for both personnel a nd test equipm ent protection.
Projection Monitor chass is have a secondary ground system s in addition to the main chassis ground. T his
secondary ground system is not isolated from the AC power line. The two ground system are electrically
separated by insulating material that must not be defeated or altered.
5.
Observe original lead dress. Take extra care to assure correct lead dress in the f ollowing areas:
sharp edges, b. near thermall y hot parts—be sure that le ads and components do not touch thermall y hot
c.
parts,
out-of-place, or fr ayed wiring. Do not chan ge spacing bet ween components, an d between com ponents and
the printed-circuit board. Check AC power 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 an d/or dam age and, if neces sar y, take corrective action to rem ove any pote ntial saf ety
hazard.
