Is the 
 indicator lit orange?
Disconnect the power cord and then reconnect it. (p.6)
Check the circuit breaker to see if power is being supplied.
Do the indicators turn off and on when 
the power cord is touched?
Turn off the projector's power, disconnect the power cord and then 
reconnect it. If this does not fix the problem, there may be a 
problem with the power cord. Stop using the projector, turn off the 
main power switch, disconnect the power cord from the electrical 
outlet, and contact your nearest dealer.
Problems with the remote control
Is the remote control light-emitting area 
facing towards the remote control light-
receiving area when it is operated?
Face the remote control towards the remote control light-receiving 
area.
The operating angle for the remote control is approximately ±30°
horizontally and approximately ±30° vertically. (Setup Guide)
Is the remote control too far from the 
projector?
The operating distance is approximately 7 m. (Setup Guide)
Is direct sunlight or strong light from 
fluorescent lamps shining onto the 
remote control light-receiving area?
Set the projector up in a location where strong light will not shine 
onto the remote control light-receiving area.
Are the batteries dead, or have the 
batteries been inserted correctly?
Insert new batteries, while making sure that they face correctly.
