NEVER PERFORM CUSTOMIZED INSTALLATIONS WITHOUT MANUFAC-
TURER°ØS APPROVAL. UNAUTHORIZED MODIFICATIONS WILL NOT ONLY
VOID THE WARRANTY, BUT MAY LEAD TO YOUR BEING LIABLE FOR ANT
RESULTING PROPERTY DAMAGE OR USER INJURY.
SERVICE WORK SHOULD BE PERFORMED ONLY AFTER YOU ARE THOR-
OUGHLY FAMILIAR WITH ALL OF THE FOLLOWING SAFETY CHECKS AND
SERVICING GUIDELINES. TO DO OTHERWISE, INCREASES THE RISK OF
POTENTIAL HAZARDS AND INJURY TO THE USER.
WHILE SERVICING, USE AN ISOLATION TRANSFORMER FOR PROTECTION
FROM A.C. LINE SHOCK.
SAFETY CHECKS
AFTER THE ORIGINAL SERVICE PROBLEM HAS BEEN CORRECTED, A CHECK
SHOULD BE MADE OF THE FOLLOWING:
SUBJECT:FIRE & SHOCK HAZARD
1. BE SURE THAT ALL COMPONENTS ARE POSITIONED IN SUCH A WAY AS
TO AVOID POSSIBILITY OF ADJACENT COMPONENT SHORTS. THIS IS
ESPECIALLY IMPORTANT ON THOSE MODULES WHICH ARE TRANS-
PORTED TO AND FROM THE REPAIR SHOP.
2. NEVER RELEASE A REPAIR UNLESS ALL PROTECTIVE DEVICES SUCH AS
INSULATORS, BARRIERS, COVERS, SHIELDS, STRAIN RELIEFS, POWER
SUPPLY CORDS, AND OTHER HARDWARE HAVE BEEN REINSTALLED PER
ORIGINAL DESIGN. BE SURE, THAT THE SAFETY PURPOSE OF THE
POLARIZED LINE PLUG HAS NOT BEEN DEFEATED.
3. SOLDERING MUST BE INSPECTED TO DISCOVER POSSIBLE COLD SOL-
DER JOINTS, SOLDER SPLASHES OF SHARP SOLDER POINTS. BE CER-
TAIN TO REMOVE ALL LOOSE FOREIGN PARTICLES.
4. CHECK FOR PHYSICAL EVIDENCE OF DAMAGE OR DETERIORATION TO
PARTS AND COMPONENTS, FOR FRAYED LEADS, DAMAGED INSULATION
(INCLUDING A.C. CORD), AND REPLACE IF NECESSARY. FOLLOW ORIGI-
NAL LAYOUT, LEAD LENGTH AND DRESS.
5. NO LEAD OR COMPONENT SHOULD TOUCH A RECEIVING TUBE OR A
RESISTOR RATED AT 1 WATT OR MORE. LEAD TENSION AROUND PRO-
TRUDING METAL SURFACES MUST BE AVOIDED.
6. ALL CRITICAL COMPONENTS SUCH AS FUSES, FLAMEPROOF RESISTOR,
CAPACITORS, ETC. MUST BE REPLACED WITH EXACT FACTORY TYPES.
DO NOT USE REPLACEMENT COMPONENTS OTHER THAN THOSE SPECI-
FIED OR MAKE UNRECOMMENDED CIRCUIT MODIFICATIONS.
7. AFTER RE-ASSEMBLY OF THE STE ALWAYS PERFORM AN A.C. LEAKAGE
TEST ON ALL EXPOSED METALLIC PARTS OF THE CABINET. (THE CHAN-
NEL SELECTOR KNOB, ANTENNA TERMINALS, HANDLE AND SCREWS) TO
BE SURE THE SET IS SAFE TO OPERATE WITHOUT DANGER OF ELECTRI-
CAL SHOCK. DO NOT USE A LINE ISOLATION TRANSFORMER DURING
THIS TEST USE AN A.C. VOLTMETER, HAVING 5000 OHMS PER VOLT OR
MORE SENSITIVITY, IN THE FOLLOWING MANNER : CONNECT A 1500 OHM
10 WATT RESISTOR, PARALLELED BY A .15 MFD. 150V A.C. TYPE CAPACI-
TOR BETWEEN A KNOWN GOOD EARTH GROUND (WATER POPE, CON-
DUIT, ETC.) AND THE EXPOSED METALLIC PARTS, ONE AT A TIME.
MEASURE THE A.C. VOLTAGE ACROSS THE COMBINATION OF 1500 OHM
RESISTOR AND .15 MFD CAPACITOR. REVERSE THE A.C. PLUG AND
REPEAT A.C. VOLTAGE MEASUREMENTS FOR EACH EXPOSED METALLIC
PART. VOLTAGE MEASURED MUST NOT EXCEED .75 VOLTS R.M.S THIS
CORRESPONDS TO 0.5 MILLIAMP A.C. NAY VALUE EXCEEDING THIS LIMIT
CONSTITUTES A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED
IMMEDIATELY.
SUBJECT : GRAPHIC SYMBOLS
THE LIGHTNING FLASH WITH ARROWHEAD SYMBOL,
WITHIN AN EQUILATERAL TRIANGLE, IS INTENDED
TO ALERT THE SERVICE PERSONNEL TO THE PRES-
ENCE OF UNINSULATED “DANGEROUS VOLTAGE”
THAT MAY BE OF SUFFICIENT MAGNITUDE TO CON-
STITUTE A RISK OF ELECTRIC SHOCK.
THE EXCLAMATION POINT WITHIN AN EQUILATERAL
TRIANGLE IS INTENDED TO ALERT THE SERVICE
PERSONNEL TO THE PRESENCE OF IMPORTANT
SAFETY INFORMATION ON SERVICE LITERATURE.
SUBJECT : X-RADIATION
1. BE SURE PROCEDURES AND INSTRUCTIONS TO ALL SERVICE PERSON-
NEL COVER THE SUBJECT OF X-RADIATION. THE ONLY POTENTIAL
SOURCE OF X-RAYS IN CURRENT T.V. RECEIVERS IS THE PICTURE TUBE.
HOWEVER, THIS TUBE DOES NOT EMIT X-RAYS WHEN THE HIGH VOLT-
AGE IS AT THE FACTORY SPECIFIED LEVEL. THE PROPER VALUE IS
GIVEN IN THE APPLICABLE SCHEMATIC. OPERATION AT HIGHER VOLT-
AGES MAY CAUSE A FAILURE OF THE PICTURE TUBE OR HIGH VOLTAGE
SUPPLY AND, UNDER CERTAIN CIRCUMSTANCES, AMY PRODUCE RADIA-
TION IN EXCESS OF DESIRABLE LEVELS.
2. ONLY FACTORY SPECIFIED C.R.T ANODE CONNECTORS MUST BE USED.
DEGAUSSING SHIELDS ALSO SERVE AS X-RAY SHIELD IN COLOR SETS.
ALWAYS RE-INSTALL THEM.
3. IT IS ESSENTIAL THAT SERVICE PERSONNEL HAVE AVAILABLE AN ACCU-
RATE AND RELIABLE HIGH VOLTAGE METER. THE CALIBRATION OF THE
METER SHOULD BE CHECKED PERIODICALLY AGAINST A REFERENCE
STANDARD. SUCH AS THE ONE AVAILABLE AT YOUR DISTRIBUTOR.
4. WHEN THE HIGH VOLTAGE CIRCUITRY IS OPERATING PROPERLY THERE
IS NO POSSIBILITY OF AN X-RADIATION PROBLEM. EVERY TIME A COLOR
CHASSIS IS SERVICED, THE BRIGHTNESS SHOULD BE RUN UP AND
DOWN WHILE MONITORING THE HIGH VOLTAGE WITH A METER TO BE
CERTAIN THAT THE HIGH VOLTAGE DOES NOT EXCEED THE SPECIFIED
VALUE AND THAT IT IS REGULATING CORRECTLY. WE SUGGEST THAT
YOU AND YOUR SERVICE ORGANIZATION REVIEW TEST PROCEDURES
SO THAT VOLTAGE REGULATION IS ALWAYS CHECKED AS A STANDARD
SERVICING PROCEDURE, AND THAT THE HIGH VOLTAGE READING BE
RECORDED ON EACH CUSTOMER°ØS INVOICE.
5. WHEN TROUBLESHOOTING AND MAKING TEST MEASUREMENTS IN A
PRODUCT WITH A PROBLEM OF EXCESSIVE HIGH VOLTAGE, AVOID
BEING UNNECESSARILY CLOSE TO THE PICTURE TUBE AND THE HIGH
VOLTAGE SUPPLY. DO NOT OPERATE THE PRODUCT LONGER THAN IS
NECESSARY TO LOCATE THE CAUSE OF EXCESSIVE VOLTAGE.
6. REFER TO HV, B+ AND SHUTDOWN ADJUSTMENT PROCEDURES
DESCRIBED IN THE APPROPRIATE SCHEMATIC AND DIAGRAMS (WHERE
USED).
SUBJECT : IMPLOSION
1. ALL DIRECT VIEWED PICTURE TUBES ARE EQUIPPED WITH AN INTEGRA
IMPLOSION PROTECTION SYSTEM. BUT CARE SHOULD BE TAKEN TO
AVOID DAMAGE DURING INSTALLATION. AVOID SCRATCHING THE

2. USE ONLY RECOMMENDED FACTORY REPLACEMENT TUBES.
SUBJECT : TIPS ON PROPER INSTALLATION
1. NEVER INSTALL ANY PRODUCT IN A CLOSED-IN RECESS, CUBBYHOLE OR
CLOSELY FITTING SHELF SPACE, OVER OR CLOSE TO HEAT DUCT, OR IN
THE PATH OF HEATED AIR FLOW.
2. AVOID CONDITIONS OF HIGH HUMIDITY SUCH AS: OUTDOOR PATIO
INSTALLATIONS WHERE DEW IS A FACTOR, NEAR STEAM RADIATORS
WHERE STEAM LEAKAGE IS A FACTOR, ETC.
3. AVOID PLACEMENT WHERE DRAPERIES MAY OBSTRUCT REAR VENTING.
THE CUSTOMER SHOULD ALSO AVOID THE USE OF DECORATIVE
SCARVES OR OTHER COVERINGS WHICH MIGHT OBSTRUCT VENTILA-
TION.
4. WALL AND SHELF MOUNTED INSTALLATIONS USING A COMMERCIAL
MOUNTING KIT, MUST FOLLOW THE FACTORY APPROVED MOUNTING
INSTRUCTIONS.A PRODUCTMOUNTED TOA SHELF ORPLATFORM MUST
RETAIN ITS ORIGINAL FEET (OR THE EQUIVALENT THICKNESS IN SPAC-
ERS)TO PROVIDE ADEQUATE AIR FLOW ACROSS THE BOTTOM, BOLTS
OR SCREWS USED FOR FASTENERS MUST NOT TOUCH ANY PARTS OR
WIRING. PERFORM LEAKAGE TEST ON CUSTOMIZED INSTALLATIONS.
5. CAUTION CUSTOMERS AGAINST THE MOUNTING OF A PRODUCT ON
SLOPING SHELF OR A TILTED POSITION, UNLESS THE PRODUCT IS
PROPERLY SECURED.
6. A PRODUCT ON A ROLL-ABOUT CART SHOULD BE STABLE ON ITS MOUNT-
ING TO THE CART. CAUTION THE CUSTOMER ON THE HAZARDS OF TRY-
ING TO ROLL A CART WITH SMALL CASTERS ACROSS THRESHOLDS OR
DEEP PILE CARPETS.
7. CAUTION CUSTOMERS AGAINST THE USE OF A CART OR STAND WHICH

SAFETY INSTRUCTION
CAUTION : Do not attempt to modify this product in any way. Unau-
thorized modifications will not only void the warranty, but may lead to
your being liable for any resulting property damage or user injury.
Service work should be performed only after you are thoroughly
familiar with all of the following safety checks and servicing guide-
lines. To do otherwise, increases the risk of potential hazards and
injury to the user.
SAFETY CHECKS
Afterthe original serviceproblem hasbeen corrected,a check should
be made of the following:
SUBJECT : FIRE & SHOCK HAZARD
1. Be sure that all components are positioned in such a way as to
avoid possibility of adjacent component shorts. This is especially
important on those chassis which are transported to and from the
repairshop.
2.Never release arepair unlessall protective devicessuch asinsula-
tors, barriers, covers, shields, strain reliefs, and other hardware
have been reinstalled per original design.
3.Soldering mustbe inspected todiscover possiblecold solderjoints,
frayed leads, damaged insulation (including A.C. cord), solder
splashes or sharp solder points. Be certain to remove all loose for-
eign particals.
4. Check for physical evidence of damage or deterioration to parts
and components, and replace if necessary follow original layout,
lead length and dress.
5.Noleads orcomponentsshould touchareceiving tubeora resistor
rated at 1 watt or more. Lead tension around protruding metal sur-
faces must be avoided.
6. All critical components such as fuses, flameproof resistors, capaci-
tors, etc. must be replaced with exact factory types. Do not use
replacement components other than those specified or make
unrecommendedcircuit modifications.
7. After re-assembly of the set always perform an A.C. leakage test
on all exposed metallic parts of the cabinet, (the channel selector
knob, antenna terminals, handle and screws) to be sure the set is
safe to operate without danger of electrical shock. Do not use a
line isolation transformer during this test. Use an A.C. voltmeter,
having 5000 ohms per volt or more sensitivity, in the following
manner : connect a 1500 ohm 10 watt resistor, paralleled by a 15
mfd. 150V A.C. type capacitor between a known good earth
ground (9water pipe, conduit, etc.) and the exposed metallic parts,
one at a time. Measure the A.C. voltage across the combination of
1500 ohm resistor and 0.15 MFD capacitor. Reverse the A.C. plug
and repeat A.C. voltage measurements for each exposed metallic
part. Voltage measured must not exceed 0.75 volts R.M.S. This
corresponds to 0.5 milliamp A.C. Any value exceeding this limit
constitutes a potential shock hazard and must be corrected imme-
diately.
GRAPHIC SYMBOLS :
The lightning flash with arrowhead symbol,
within an equilateral triangle, is intended to alert
theservice personnelto the presenceof uninsu-
lated “dangerous voltage” that may be of suffi-
cienty magnitude to constitute a risk of electric
shock.
The exclamation point within an equilateral tri-
angle is intended to alert the service personnel
to the presence of important safety information
inserviceliterature.
Fuse symbol is printed on pcb adjacent to the
fuse, with “RISK OF FIRE REPLACE FUSE AS
MARKED”. The symbol is explained in the ser-
vice manual with the following wording or equiv-
alent.
“CAUTION : FOR CONTINUED PROTECTION AGAINST FIRE
HAZARD, REPLACE ONLY WITH SAME TYPE (6.3A, 250V)” and
“ ATTENTION : AFIN D’ASSU UNE PROTECTION PERMANENTE
CONTRE LES RISQUES D’INCENDIE, REMPLACER UNIQUE-
MENT PAR UN FUSIBLE DE MEME TYPE ET DE ”6.3A, 250V”.
SUBJECT : X-RADIATION
1. Be sure procedures and instructions to all service personnel cover
the subject of X-rays in current T.V. receivers is the picture tube.
However, this tube does not emit X-rays when the high voltage is
atthe factoryspecifiedlevel. Theproper valueisgiven inthe appli-
cable schematic. Operation at higher voltages may cause a failure
of the picture tube or high voltage supply and, under certain cir-
cumstances, may produce radiation in excess of desirable levels.
2. Only factory specified C.R.T. anode connectors must be used.
Degaussing shields also serve as X-ray shield in color sets.
Alwaysre-install them.
3. It is essential that the serviceman has available an accurate and
reliable high voltage meter. The calibration of the meter should be
checked perio - dically against a reference standard. Such as the
one available at your distributor.
4. When the high voltage circuitry is operating properly there is no
possibility of an X-radiation problem. Every time a color chassis is
serviced, the brightness should be run up and down while monitor-
ingthe highvoltage witha meterto becertain thatthe highvoltage
does not exceed the specified value and that it is regulating cor-
rectly. We suggest that you and your service organization review
test procedures so that voltage regulation is always checked as a
standardservicing procedure.Andthat thehighvoltage readingbe
recorded on each customer’sinvoice.
5. When troubleshooting and making test measurements in a
receiver with a problem of excessive high voltage, avoid being
unnecessarilyclosetothepicturetubeandthehighvoltagecompartment.
Do not operate the chassis longer than is necessary to locate the
cause of excessive voltage.
6. Refer to HV, B+and Shutdown adjustment procedures described in
the appropriate schematic and diagrams(where used).

SAFETY INSTRUCTION
SUBJECT : IMPLOSION
1. All direct viewed picture tubes are equipped with an integral implo-
sion protection system, but care should be taken to avoid damage
during installation. Avoid scratching the tube. If scratched, replace
it.
2. Use only recommended factory replacement tubes.
SUBJECT : TIPS ON PROPER INSTALLATION
1. Never install any receiver in closed-in recess, cubbyhole or closely
fitting shelf space over, or close to heat duct, or in the path of
heatedair flow.
2. Avoid conditions of high humidity such as : Outdoor patio installa-
tions where dew is a factor. Near steam radiators where steam
leakage is a factor, etc.
3. Avoid placement where draperies may obstruct rear venting. The
customer should also avoid the use of decorative scarves or other
coverings which might obstruct ventilation.
4. Wall and shelf mounted installations using a commercial mounting
kit, must follow the factory approved mounting instructions. A
receiver mounted to a shelf or platform must retain its original
feet(or the equivalent thickness in spacers) to provide adequate
are flow across the bottom, bolts or screws used for fasteners
must not touch and parts or wiring. Perform leakage test on cus-
tomized installations.
5. Caution customers against the mounting of a receiver on sloping
shelf or a tilted position, unless the receiver is properly secured.
6. A receiver on a roll-about cart should be stable on its mounting to
thecart. Cautionthecustomer onthe hazardsoftrying toroll acart
with small casters across thresholds or deep pile carpets.
7.Caution customers againstthe useof a cartor standwhich has not
been listed by underwriters laboratories, inc. For use with their
specific model of television receiver or generically approved for
usewith T.V.’s of the same or larger screen size.
