Chapter 3 Basic Operation — Switching on/off the projector
3) Wait until the power indicator  of the projector lights in red (and 
the fan stops) for approximately 170 seconds.4) Press the  side of the  
switch to turn off the power.
Note
r
f Do not turn on the power and project images immediately after turning th\
e projector off.
Turning on the power while the lamp is still hot may shorten the lamp life.
r
f The lamp indicators will not light on for about 75 seconds after the projector is switched of
f 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  lights in red.
r
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 76) on the menu is set to [ECO], the power consumption during standby can be conserved.
Direct power off function
Even if the  switch is  during projection or immediately after the luminous lamp is turned of
f, 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  
switch cannot easily be turned , 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 of f.
Note
r
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  will light in green a while after the power circuit breaker is turned on and then transitions to image 
projection.
r
f It may take more time than usual to project the next time that the power is turned on if direct power of
f is used to cool.
r
f When packing for shipment or storage, ensure that the fan is stopped.
