X-radiation
- TUBE: The primary source of X-
radiation in this receiver is the picture tube. The tube
utilized for the above mentioned function in this
chassis is specially constructed to limit X-radiation
emissions.
For continued X-radiation protection, the replacement
tube must be the same type as the original, Hitachi
approved type.
When troubleshooting and making test measure-
ments in a receiver with a problem of excessive high
voltage, avoid being unnecessarily close to the picture
tube and the high voltage component.
h. X-radiation Shield -
1. This receiver is provided with X-ray shield plates
for protection against X-radiation. Do not remove
X-ray shield plates A, B, C, or D shown in Fig. 1
unnecessarily, when troubleshooting and/or
making test measurements.
2. To prevent X-radiation, after replacement of
picture tube and lens, confirm these components
to be fixed correctly to bracket and cabinet, and
not to be taken off easily.
Do not operate the chassis longer than is necessary
to locate the cause of excessive voltage.
