Problems Solving
The remote control does not work
Check
Is the remote control light-emitting area
facing towards the remote control light-
receiving area when it is operated?
Is the remote control too far from the
projector?
Is direct sunlight or strong light from
fluorescent lamps shining onto the
remote control light-receiving area?
Are the batteries dead, or have the
batteries been inserted correctly?
Has a remote control button been pressed
for more than 30 seconds?
Face the remote control towards the remote control light-receiving area.
The operating angle for the remote control is approximately ±30º horizontally and approximately ±15º
vertically. sQuick Start Guide
The operating range for the remote control is approximately 6m. sQuick Start Guide
Set the projector up in a location where strong light will not shine onto the remote control light-receiving
area.
Insert new batteries, while making sure that they are inserted the correct way around.
If any of the buttons on the remote control are pressed down for more than 30 seconds, the remote control
stops sending signals (remote control's sleep mode) . The purpose of this is to prevent the batteries from
being consumed due to something being placed on top of the remote control.
When the button is released, normal remote control operation will resume.
