If the power is turned off using the POWER button, the cooling fan will continue to operate (for approximately 60
seconds) while the inside of the Projector is still at a high temperature. Do not turn the MAIN POWER switch to
the OFF position, disconnect the power cord plug from the wall socket or shut off the mains power supply until
the cooling fan stops operating.
When POWER is turned on, and while the LCD Projector is warming up, the “Panasonic” logo will be projected
on the screen for approximately 30 seconds. If you press INPUT during the 30 seconds that “Panasonic” is
projected, the “Panasonic” logo will disappear. During the warm up period, no other picture can be projected on
the screen.
This LCD Projector can display a favorite back-screen instead of the “Panasonic” logo. Please see “Setting the
favorite back-screen” on page 27 to use this feature.
If the POWER switch is accidentally turned off, the picture may not be projected even if the power is immediately
turned back on. In this case, wait a while (approx. 60 seconds) for the lamp to cool down before turning the
power back on again.
The remote power function may cause the operation of the POWER button on the remote control to be disabled
temporarily. For details about this function, refer to page 25.
If the MAIN POWER switch has not been turned off, the Projector will still draw approximately 20 W of power,
even when the POWER button has been turned off and the fan has stopped.
