To protect the light source lamp, the LAMP indicator blinks as long as

 

a minimum of cooling is necessary. The power cannot be turned back

 

 

on during this time. Unplugging the power cord at this time will shorten

 

the lamp’s duration life.

Notes

•The projector consumes about 20W of power in the standby mode. We recommend you unplug the power cord when not using the projector for long periods of time.

•Be sure that the LAMP indicator has turned off before unplugging the power cord. Cutting the power by unplugging the power cord while the projector is operating or the light source lamp is being cooled will shorten the lamp’s duration life. Should a fault or some other irregularity arise with this unit, unplug the power cord.

•When reinserting the power plug before the lamp has cooled, please wait until the lamp has cooled sufficiently before use. When the lamp is at a high temperature, it may not light and it’s life duration will be shortened.
