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 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.
Product 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.
