Notes
A buzzing sound may be heard when the plasma television is turned on in a very quiet
room. This is due to the plasma panel drive circuit when it is functioning. The buzzing
sound is normal and is not a malfunction.
Some infrared rays are emitted from the plasma television panel that might affect the
operation of other infrared controlling equipment.
High precision technology is used to manufacture the plasma television. But there
maybe points that do not illuminate, points that are too bright, and points with color
different from that of the periphery. Please note that this is not a malfunction.
In some cases, residual images may remain after the short term display of still images
when the picture changes.
Ihe plasma display panel display images by means ot electrical discharges inside the
3anel. This may cause the temperature of the panel surface to increase. Please note that
this is not a malfunction.
A reintorced glass tilter is installed over the plasma panel surtsce. A strong _mpsct to
the front panel risk a danger of glass breakage.
Please transport the plasma television in it's packing box and placed in an upright
)osition. Do not transport the plasma television in a horizontal position. This increases
_bility of panel breakage and pixel failure.
When a screen is seen at point-blank range, a random fine grain may be visible in the
dark areas of the picture.
High temperature affect the electric discharge/luminescence characteristic of the PDP
)anel. Do not place the plasma television in high temperature environments.
Operating altitude: 800 to 1,114hPa (6,194ft to -2,484ft). Operating temperature: 41°F
to 95°F.
Storage altitude: 300 to 1,114hPa (31,912ft to -2,484ft). Storage temperature: 5°F to
140°F
Repeatedly turning the p}asma te}evision Power ON and OFF at short )nterva)s may
result in failure of the television.
The on-screen motion of an actor's tips or other moving object may not
be in sy_c with the associated audio heard from the TV's speakers. This
is caused by timing differences in the broadcast signal or DVD content
and is not caused by a defect in the television.
