fied technicians have the necessary test equipment and
tools, and have been trained to properly and safely repair
complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the prod-

the necessary repairs and should instead refer to a quali-
fied service technician.
WARNING
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in HITACHI television
receivers have special safety related characteristics. These
are often not evident from visual inspection nor can the pro-
tection afforded by them necessarily be obtained by using
replacement components rated for higher voltage, wattage,
etc. Replacements parts which have these special safety
characteristics are identified in this Model Service Manual.
Electrical components having such features are identified
with an A mark in the schematics and parts list in this
Model Service Manual.
The use of a substitute replacement component which does
not have the same safety characteristics as the HITACHI
recommended replacement one, shown in the parts list in
this Model Service Manual, may create shock, fire, X-Ra-
diation, or other hazards.
Production Safety is continuously under review and new in-
structions are issued from time to time. For the latest infor-
mation, always consult the current HITACHI Service Manual.
A subscription to, or additional copies of HITACHI Service
Manual may be obtained at a nominal charge from HITACHI
SALES CORPORATION.
X-Radiation
TUBE: The primary source of X-Radiation in this receiver is
the picture tube. The tube utilized in this chassis is specially
constructed to limit X-Radiation emission. For continued X-
Radiation protection, the replacement tube must be the same
type as the original HITACHI approved type.
When troubleshooting and making test measurements in a
receiver with an excessive high voltage problem, avoid com-
ing unnecessarily close to the picture tube and the high
voltage component.
Lead in solder used in this product is listed by the California
Health and Welfare agency as a known reproductive toxi-
cant which may cause birth defects or other reproductive
harm (California Health and Safety Code, Section 25249.5).
When servicing or handling circuit boards and other com-
ponents with lead in solder, avoid unprotected skin contact
with the solder. Also, when soldering do not inhale any
smoke or fumes produced.
SAFETY NOTICE
USE ISOLATION TRANSFORMER
WHEN SERVICING
Components having special safety characteristics are iden-
tified by ,!!!!, on the parts list in this Model Service Manual
and its supplements and bulletins. Before servicing this, it
is important that the service technician read and follow the
"Safety Precautions" and the "Product Safety Notices" in this
Service Manual.
. For continued X-Radiation protection, replace picture tube
with original type or Hitachi equivalent type.
POWER SOURCE
This television receiver is designed to operate on 120 Volts/
60Hz, AC house current. Insert the power cord into a 120
Volts/GOHz outlet.
NEVER CONNECT THE TV TO OTHER THAN THE
SPECIFIED VOLTAGE OR TO DIRECT CURRENT.
Do not operate the chassis longer than is necessary to lo-
cate the cause of the excessive voltage.
