CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION:

TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT OPEN REAR COVER. NO USER-SERVICEABLE

PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

This symbol warns the user that unin-

sulated voltage within the unit may have

sufficient magnitude to cause electric

shock. Therefore, it is dangerous to make

any kind of contact with any part inside of

this unit.

This symbol alerts the user that important

literature concerning the operation and

maintenance of this unit has been

included.

Therefore, it should be read carefully in

order to avoid any problems.

ATTENTION

RISQUE D'ELECTROCUTION

NE PAS OUVRIR

ATTENTION:

POUR EVITER LES RISQUES D' ELECTROCUTION, NE PAS ENLEVER LE CONVERCLE ARRÈRE. AUCUN DES

ELEMENTS INTERNES NE DOIT ETRE REPARE PAR L'UTILISATEUR. NE CONFIER L' ENTRETIEN QU'A UN

PERSONNEL QUALIFIE.

L'éclair fléché dans un triangle équilatéral est

destiné à avertir l'utilisateur de la présence,

dans l'appareil, d'une zone non-isolée soumise

à une haute tension dont l'intensité est suffi-

sante pour constituer un risque d'électro-

cution.

Le point d'exclamation dans un triangle équi-

latéral est destiné à attirer l' attention de l'uti-

lisateur sur la présence d'informations de

founctionnement et d'entretien importantes dans

WARNING

HEATSINK MAY BE ENERGIZED.

TEST BEFORE TOUCHING.

1. Before returning an instrument to the customer, al-

ways make a safety check of the entire instrument, in-

cluding, 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 pro-

tective shields, including any removed for serv-

icing 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 fishpapers,adjustment and

compartment covers/shields, and isolation re-

sistor/capacitor networks. Do not operate this

instrument or permit it to be operated with-

out 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 volt-

age. Such opening include,but are not limited to,

(1) spacing between the picture tube and the

cabinet mask, (2) excessively wide cabinet ven-

tilation slots, and (3) an improperly fitted and/or

incorrectly secured cabinet back cover.

c. Leakage Current Hot Check -- With the instru-

ment completely reassembled,plug the AC line

cord directly into a 240V 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 In-

stitutes (ANSI) C101.1 Leakage Current for Ap-

pliances and Underwriters Laboratories(UL)

1950. With the instrument AC switch first in the

ON position and then in the OFF position, mea-

sure

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 ex-

posed metal parts that offer an electrical return

path to the chassis. Any current measured must

not exceed 3.5 milliamp. Reverse the instru-

ment 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.

AC Leakage Test

2. Read and comply with all caution and safety-related

notes on or inside the Monitor cabinet, on the Pro-

jection 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 out-

put connections might alter the safety characteris-

tics of this Monitor and create a hazard to the user.

Any design alterations or additions will void the

manufacturer's warranty and will make you,the

servicer,responsible for personal injury or property

damage resulting therefrom.

4. Hot Chassis Warning -- a. Some MultiSync 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 in-

serted correctly, with an AC voltmeter measure be-

tween the chassis and a known earth ground. If a

voltage reading in excess of 1.0V is obtained, re-

move and reinsert the AC power plug in the oppo-

site polarity and again measure the voltage poten-

tial between the chassis and a known earth ground.

b. Some Plasma chassis normally have 85V AC

(RMS), between chassis and earth ground regard-

less 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 Plasma chassis

have a secondary ground systems in addition to the

main chassis ground. This secondary ground sys-

tem is not isolated from the AC power line. The two

ground system are electrically separated by insulat-

ing material that must not be defeated or altered.
