Operating range of the remote
control unit
When operating the remote control unit, point it at the
remote sensor (Î) located on the front panel of the main
unit. The remote control unit is operable up to 23 feet
(7 m) from the unit and within a 30 angle on each side of
the sensor.
If you are having difficulty with operation of the
remote control unit
¶ The remote control unit may not operate if there are objects
placed between it and the display.
¶ Operational distance will gradually become shorter as the
batteries begin to wear out, replace weak batteries with new
ones as soon as possible.
¶ This unit discharges infrared rays from the screen. Placing a
video deck or other component that is operated by an infrared
remote control unit near this unit may hamper that
component's reception of the remote control's signal, or
prevent it from receiving the signal entirely. Should this occur,
move the component to a position further away from this unit.
¶ Depending on the installation surroundings, this unit's remote
control unit may be influenced by the infrared rays discharged
from the plasma display, hampering reception of its rays or
limiting its operational distance. The strength of infrared rays
discharged from the screen will differ according to the picture


What may at first seem to be an malfunction, may be
remedied with a quick check.
Please check to see if a warning is displayed on the
screen. If displayed, refer to page 24 and check the
mode. If there is no display check to see if the problem is
listed below. The problem may also be caused by
something other than this unit so please also check the
