Direct Power Off Function - Panasonic PT-DW640EL Operating Instructions Manual

Chapter 3 Basic Operation — Switching on/off the projector
3)
Wait until the power indicator <ON(G)/
STANDBY (R)> of the projector lights in red (and
the fan stops) for approximately 170 seconds.
Note
f Do not turn on the power and project images immediately after turning the projector off.
Turning on the power while the lamp is still hot may shorten the lamp life.
f The lamp indicators will not light on for about 75 seconds after the projector is switched off and the luminous lamp cooling has started even
if the power is switched. The indicators may not light when the power is switched on even after this time. In such a case, turn the power on
again after the power indicator <ON (G)/STANDBY (R)> lights in red.
f The projector consumes power when the main power of the projector is on, even if the power standby < v > button is pressed and
the power is switched off.
When [STANDBY MODE] ( x page 78) on the menu is set to [ECO], the power consumption during standby can be conserved.

Direct power off function

Even if the <MAIN POWER> switch is <OFF> during projection or immediately after the luminous lamp is turned off, the electricity stored in the
room will drive the fan and cool the luminous lamp. When mounting on the ceiling or other environment where the projector <MAIN POWER>
switch cannot easily be turned <OFF>, the power can be shut down directly from the power breaker. This method is safe in the event of a
blackout or if the power cord is removed directly after the projector is switched off.
Note
f If the power was shut down directly from the power circuit breaker during projection the last time that the projector was used, the power
indicator <ON (G)/STANDBY (R)> will light in green a while after the power circuit breaker is turned on and then transitions to image
projection.
f It may take more time than usual to project the next time that the power is turned on if direct power off is used to cool.
f When packing for shipment or storage, ensure that the fan is stopped.
