SAFETY INSTRUCTION
WARNING: BEFORE EXAMINING AND SERVICING THIS CHASSIS,
READ CAREFULLY THE FOLLOWING SAFETY INSTRUCTIONS.
X-RAY RADIATION PRECAUTION
1. The EHT must be checked every time the receiver is serviced to ensure that the CRT does not
emit X-ray radiation as result of excessive EHT voltage. The nominal EHT for this receiver is
27.5kv at zero beam current (minimum brightness) operating at AC 220V. The maximum
EHT voltage permissible in any operating circumstances must not exceed 30KV. When
checking the EHT, use the High Voltage Check procedure in this manual using an accurate
EHT voltmeter.
2. The only source of X-RAY radiation in this TV is the CRT. The TV minimizes X-RAY
radiation, which ensures safety during normal operation. To prevent X-ray radiation, the
replacement CRT must be identical to the original fitted as specified in the parts list.
3. Some components used in this TV have safety related characteristics preventing the CRT from
emitting X-ray radiation. For continued safety, replacement component should be made after
referring the PRODUCT SAFETY NOTICE below.
4. Service and adjustment of the TV may result in changes in the nominal EHT voltage of the
CRT anode. So ensure that the maximum EHT voltage does not exceed the rated value after
service and adjustment.
