g. 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

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

of
picture tube and lens, confirm
these components
to be fixed correctly
to bracket

and
not to be taken off easily.
