PRPDUCT SAFETY SERVICING GUIDELINES FOR VIDEO PRODUCTS 

 

CAUTION:

 

DO NOT ATTEMPT TO MODIFY THIS PRODUCT IN 

ANYWAY. NEVER PERFORM  CUSTOMINIZED INSTALLATIONS 

WITHOUT MANUFACTURER’S APPROVAL. UNAUTHORIZED 

MODIFICATIONS WILL NOT ONLY VOID THE WARRANTY, BUT MAY 

LEAD TO YOUR BEING LIABLE FOR ANY RESULTING PROPERTY 

DAMAGE OR USER INURY. 

SERVICE WORK SHOULD BE PERFORMED ONLY AFTER YOU ARE 

THOROUGHLY FAMILIAR WITH ALL OF THE FOLOWING SAFETY 

CHECKS AND SERVICING GUIDELINS. 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 CORRCTED, 

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 COMPONET SHORTS. 

THIS IS ESPECIALLY IMPORTANT ON THOSE MODULES WHICH ARE 

TRANSPORTED 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 PERORIGINAL DESIGN. BE SURE THAT THE 

SAFETY PURPOSE OF THE POLARIZED LINE PLUG HAS NOT BEEN 

DEFEATED. 

3. SOLDERING MUST BE INSPECTED TO DISVCOVER POSSIBLE 

COLD SOLDER JOINTS, SOLDER SPLASHES OR SHARP SOLDER 

POINTS. BE CERTAIN TO REMOVE

 

ALL LOOSE FOREIGN PARTICLES. 

4. CHECK FOR PHYSICAL EVIDENCE OF DAMAGE OR 

DETERRIORATION TO PARTS AND COMPONENTS. FOR FRAYED 

LEADS, DAMAGED INSULATION (INCLUDING A.C. CORD).AND 

REPLACE IF NECESSARY FOLLOW ORIGINAL LAYOUT, LEAD 

LENGTH AND DRESS. 

5. NO LEAD OR COMPONENT SHOULD TOUCH A RECIVING TUBE 

OR A RESISTOR RATED AT 1 WATT OR MORE. LEAD TENSION 

AROUD PROTRUNING METAL SURFACES MUST BE AVOIDED. 

6. ALL CRITICAL COMPONENTS SUCH AS FUSES,  FLAMEPRO OF 

RESISTORS, CAPAICTORS, ETC. MUST BE REPLACED WITH EXACT 

FACTORY TYPES. DO NOT USE REPLACEMENT COMPONETS 

OTHER THAN THOSE SPECIFIED OR MAKE UNRECOMMENDED 

CIRCUIT 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 ADN SCREWS) TO BE SURE THE SET IS SAFET 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 1500OHM 10 WATT 

RESISTOR, PARALLELED BY A. 15 MFD, 150.V A.C. TYPE CAPACITOR 

BETWEEN A KNOWN GOOD EARTH GROUND (WATER PIPE, 

CONDUIT, ETC.) AND THE EXPPOSED 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 MEASURE MUST NOT EXCEED 75 VOLTS R.M.S. THIS 

CORRESPONDS TO 0.5 MILLIAMP A.C. ANY VALUE EXCEEDING THIS 

LIMIT CONSTITUTED A POTENTIAL SHOCK HAZARD AND MUST BE 

CORRECTED IMMEDIATELY. 

 

SUBJECT: GRAPHIC SYMBOLS 

 

 

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 

FACTOR, ETC. 

3. AVOID PALCEMNET 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 PRODUCT 

MOUNTED TO A SHELF OR PLATFORM MUST RETAIN ITS 

ORIGINAL FEET (OR THE EQUIVALENT THICKNESS IN 

SPACERS) TO PROVIDE ADEQUATE AIP 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 AGNINST THE MOUNTING OF A 

PRDUCT ON SLOPING SHELF OR TILTED POSITION, UNLESS 

THE PRODUCT IS PROPERLY SECURED. 

6. A PRODUCT ON A ROLL-ABOUT CART SHOULD BE STABLE 

ON ITS MOUNTING TO THE CART. CAUTION THE CUSTOMER 

ON THE HAZARDS OF TRYING TO ROLL A CART WITH SMALL 

CASTERS ACROSS THRESHOLDS OR DEEP POLE CARPETS. 

7. CAUTION CUSTOMERS AGAINST THE USE OF A CART  OR 

STAAND WHICH HAS NOT BEEN LISTED BY UNDERWRITERS 

LABORATORIES, INC. FOR USE  WITH THEIR SPECIFIC 

MODEL OF THELVISION RECEIVER OR GENERICALLY 

APPROVED FOR USE WITH T.V.’ S OF THE SAME OR LARGER 

SCREEEN SIZE. 

8. CAUTION CUSTOMERS AGAINST THE USE OF EXTENSION 

CORDS, EXPLAIN THAT A FOREST OF EXTENSIONS 

SPROUTING FROM A SINGAL OUTLET CAN LEAD TO 

DISASTROUS CONSEQUENCES TO HOME AND FAMILY. 

THE LIGHTNING FASH WITH ARROWHEAD SYMBOL, WITHIN AN 

EQUILATERAL TRIANGLE, IS INTENDED TO ALERT THE USER TO THE 

PRESENCE OF UNINSULATED “DANGEROUS VOLTAGE” WITHIN THE 

PRODUCT’ S ENCLOSURE THAT MAY BE OF SUFFCIENT MAGNITUDE TO 

CONSTITUTE A RISK OF ELECTRIC SHOCK.

 

THE EXCELAMATION POINT WITHIN AN EQUILATERAL TRIANGLE  IS 

INTENDED TO ALERT THE USER TO THE PRESENCE OF IMPORANT 

OPERATING AND MAINTENANCE (SERVICING) INSTRUCTIONS IN THE 

LITERATURE ACCOMPANYING THE APPLIANCE.
