CAUTION

: Before servicing the chassis, read the “Safely Precaution”.

“X -Ray radiation Precaution” and “Product Safety Notice” in this manual.

X-RAY RADIATION PRECAUTION

1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To

Avoid such hazards the high voltage must be specified limit. The normal value of the

high voltage of this receiver is 24.5KV +/-2KV under 230V AC power source. The

high voltage must not exceed 27KV.

2. Each time a receiver requires servicing the high voltage should be checked following

the HIGH VOLTAGE CHECK procedure in this manual. It is recommended the

reading of the high voltage be recorded as a part of the service record. It is

important to use an accurate and reliable high voltage meter.

3. The primary source of X -RAY RADIATION in this TV receiver is the picture tube. For
