Continuous on-screen displays such as video games, stock market quotations, computer generated graphics, and
other fixed (non-moving) patterns can cause permanent damage to projection television receivers. Such PATTERN
BURNS constitute misuse and are NOT COVERED by your HITACHI Factory Warranty.

PROTECTION AND LOCATION OF YOUR TELEVISION
16-1. If an outside antenna is connected
to the television, be sure the
antenna system is grounded so as
to provide some protection against
voltage surges and built-up static
charges. Section 810 of the
National Electrical Code, NFPA
No. 70-1975, provides information
with respect to proper grounding
of the mast and supporting
structure, grounding of the lead-in
wire to an antenna discharge unit,
size of grounding conductors,
location of antenna discharge unit
connection to grounding
electrode, and requirements for
the grounding electrode.
16-2
. Note to CATV system installer:
(Only for television with CATV
reception). This reminder is
provided to call the CATV system
installer s attention to Article 820-
40 of the NEC that provides
guidelines for proper grounding
and, in particular, specifies that
the cable ground shall be
connected to the grounding
system of the building, as close
to the point of cable entry as
practical.

17. An outside antenna system should
not be located in the vicinity of
overhead power lines or other
electrical lights or power circuits,
or where it can fall into such power
lines or circuits. When installing an
outside antenna system, extreme
care should be taken to keep from
touching such power lines or
circuits as contact with them might
be fatal.
18. For added protection for the
television during a lightning storm,
or when it is unused for long
periods of time, unplug it from the
wall outlet and disconnect antenna.
This will prevent damage due to
lightning and power-line surges.
