Epson 450W 사용자 가이드

■

Point the remote control towards the projector’s receiver. Make 
sure you are within 19.7 feet (6 meters) of the projector and 
within a 30° horizontal angle and a 15° vertical angle from the 
projector’s front or back receiver.

■

The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 106. 

■

Dim the room lights and turn off any fluorescent lights. Make 
sure the projector is not in direct sunlight. Strong lighting, 
especially fluorescent lights, may affect the projector’s infrared 
receivers. Also, turn off any nearby equipment that emits infrared 
energy, such as a radiant room heater. 

■

If you can’t adjust the room lighting, you can turn off one of the 
remote receivers by using the Settings menu. Make sure the 
receivers are not both turned off (see page 66).

■

Check to see if a button on the remote control is stuck down, 
causing it to enter sleep mode. Release the button to wake the 
remote.

■

If you want to use the remote control as a wireless mouse (or to 
move through presentation slides), make sure 

USB Type B

 in the 

Extended menu is set to Wireless Mouse (see page 68). Also, 
make sure you have connected the USB cable.
