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 protection afforded by them
necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this Service Manual.
Electrical components having such features are identified
with an a mark in the schematics and parts list in this
Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
HITACHI-recommended replacement component, shown
in the parts list in this Service Manual, may create shock,
fire, X-Radiation, or other hazards.
Production safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current HITACHI Service
Manual. A subscription to, or additional copies of
HITACHI Service Manuals may be obtained at a nominal
charge from HITACHI Sales Corporation.

CHASSIS GROUND
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 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 measurements in
a receiver with an excessive high voltage problem, avoid
being unnecessarily close to the picture tube and the high
voltage component.
Do not operate the chassis longer than is necessary to
locate the cause of excessive voltage.
PRODUCT SAFETY NOTICE
This Service Manual is intended for qualified service
technicians; it is not meant for the casual do-it-yourselfer.
Qualified 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 safety and reliability of the product and may
void warranty. Consumers should not risk trying to do the
necessary repairs and should refer to a qualified service
technician.

Code, Section 25249.5).
When servicing or handling circuit boards and other
components which contain lead in solder, avoid
unprotected skin contact with solder. Also, when
soldering do not inhale any smoke or fumes produced.
SAFETY NOTICE
USE ISOLATION TRANSFORMER
WHEN SERVICING
Components having special safety characteristics
identified by aon 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/ 60H2, 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.
