Remote control problems
If the remote control does not operate: 
If the indicator light on the front of the remote control blinks 
when you press buttons, the remote control is working properly. 
 
If the light does not blink, install two new AAA batteries in the

Open the on-screen menu and select help > Diagnostics. Run 
remote control.

Check whether the projector’s IP address shown in the on-screen 
menu is 169.254.x.x. If the projector is set to use a DHCP server, 
this address means no DHCP server is available. If the projector 
does not use a DHCP server, this address means no IP address is
