SWITCH)
once.
2. If there is still no power,
wait 30 seconds and
press the
POWER
SWITCH again.
3. If there is still no power,
unplug the power cord
from the wall. Wait 30
seconds and plug the

This protective technology

lasting entertainment from
your
HITACHI Plasma
Television.
DO
Dust the screen and cabinet with a soft cloth.
Clean the screen with a soft cloth moistened in warm
water and dry with a soft cloth. A mild soap may be
used if the screen is extremely dirty.
Place your Plasma Television away from extreme heat,
humidity, and extremely dusty places.
Remove the plug from the wall outlet if your Plasma
Television will not be used for a long period of time, for
instance, when you go on vacation.
DO NOT
Do not clean your screen with strong cleaners, polishes
or a chemically treated cloth.
Do not place rubber or vinyl products or cellophane
tape on your Plasma Television.
Avoid repeatedly touching the screen.
Do not subject the remote control to shocks such as
dropping it on the floor, etc. This may cause damage to
the precision parts.
Avoid placing the remote control in a high humidity
place or getting it wet. Do not leave it on or near a
heater. Excessive heat or moisture may cause the unit
to fail.
When the batteries run down, remote control operation
will become erratic or become unresponsive. Replace
the old batteries with two new “AA” size batteries. Do
not use an old battery with a new battery.
Exposing the screen to direct sunlight for a long period
of time or heat may cause damage to the plasma
screen.
