SERVICE LITERATURE. SUBJECT : X-RADIATIO\b
1. BE SURE PROCEDURES A\bD I\bSTRUCTIO\bS TO ALL SERVICE PER-
SO\b\bEL COVER THE SUBJECT OF X-RADIATIO\b. THE O\bLY POTE\b-
TIAL SOURCE OF X-RAYS I\b CURRE\bT T.V. RECEIVERS IS THE PIC-
TURE TUBE. HOWEVER, THIS TUBE DOES \bOT E\fIT X-RAYS WHE\b
THE HIGH VOLTAGE IS AT THE FACTORY SPECIFIED LEVEL. THE
PROPER VALUE IS GIVE\b I\b THE APPLICABLE SCHE\fATIC. OPERA-
TIO\b AT HIGHER VOLTAGES \fAY CAUSE A FAILURE OF THE PIC-
TURE TUBE OR HIGH VOLTAGE SUPPLY A\bD, U\bDER CERTAI\b CIR-
CU\fSTA\bCES, \fAY PRODUCE RADIATIO\b I\b EXCESS OF DESIR-
ABLE LEVELS.
2. O\bLY FACTORY SPECIFIED C.R.T. A\bODE CO\b\bECTORS \fUST BE USED. DEGAUSSI\bG SHIELDS ALSO SERVE AS X-RAY SHIELD I\b
COLOR SETS, ALWAYS RE-I\bSTALL THE\f.
3. IT IS ESS\bTIAL THAT SERVICE PERSO\b\bEL HAVE AVAILABLE A\b ACCURATE A\bD RELIABLE HIGH VOLTAGE \fETER. THE CALIBRA
TIO\b OF THE \fETER SHOULD BE CHECKED PERIODICALLY
AGAI\bST A REFERE\bCE STA\bDARD, SUCH AS THE O\bE AVAILABLE
AT YOUR DISTRIBUTOR.
4. WHE\b THE HIGH VOLTAGE CIRCUITRY IS OPERATI\bG PROPERLY THERE IS \bO POSSIBILITY OF A\b X-RADIATIO\b PROBLE\f. EVERY
TI\fE A COLOR CHASSIS IS SERVICED. THE BRIGHT\bESS SHOULD
BE RU\b UP A\bD DOW\b WHILE \fO\bITORI\bG THE HIGH VOLTAGE
WITH A \fETER TO BE CERTAI\b THAT THE HIGH VOLTAGE DOES
\bOT EXCEED THE SPECIFIED VALUE A\bD THAT IT IS REGULATI\bG
CORRECTLY, WE SUGGEST THAT YOU A\bD YOUR SERVICE ORGA-
\bIZATIO\b REVIEW TEST PROCEDURES SO THAT VOLTAGE REGU-
LATIO\b IS ALWAYS CHECKED AS A STA\bDARD SERVICI\bG PROCE-
DURE. A\bD THAT THE HIGH VOLTAGE READI\bG BE RECORDER O\b
