SAFETY INSTRUCTIONS
Warning: Before servicing this chassis, read the “X-Ray radiation precaution”, “Safety precaution”
and “product safety notice” instructions below.
X-RTY Radiation precaution
1. The EHT must be checked every time the TV is serviced to ensure that the CRT does not
emit X-ray radiation as result of excessive EHT voltage. The nominal EHT for this TV is
24.5KV (for 21” CRT only) 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 in this TV is the CRT. To prevent X-RAY radiation, the
replacement CRT must be identical to the original fitted as specifies 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.
SAFETY PRECAUTION
1. The TV has a nominal working EHT voltage of 24.5KV. Extreme caution should be
exercised when working on the TV with the back removed.
a. Do not attempt to service this TV if you are not conversant with the precautions and
procedures for working on high voltage equipment.
b. When handling or working on the CRT, always discharge the anode to the TV
chassis before removing the anado cap in case of electric shock.
c. The CRT, if broken, will violently expel glass fragments. Use shatterproof goggles
and take and take extreme care while handling.
d. Do not hold the CRT by the neck as this is a very dangerous practice.
2. It is essential that to maintain the safety of the customer all power cord forms be replaced
exactly as supplied from factory.
3. Voltage exits between the hot and cold ground when the TV is in operation, Install a suitable
transformer of beyond rated overall power when servicing or connecting any test equipment
for the sake of safety.
4. Replace blown fuses within the TV with the fuse specified in the parts list.
