Is the audio cable's specification "No resistance"? When using a commercially available audio cable, make sure it is labelled "No resistance".
Check Remedy
Is the remote control light-emitting area pointing towards the
remote receiver on the projector when it is operated? Point the remote control towards the remote receiver.
The operating angle for the remote control is about 30
°
horizontally, and about 15
°
vertically.
Is the remote control too far from the projector? The operating range for the remote control is about 6 m.
Is direct sunlight or strong light from fluorescent lamps
shining onto the remote receiver? Set the projector up in a location where strong light does not shine onto the remote receiver.
Are the batteries dead or have the batteries been inserted
correctly? Make sure the batteries are inserted correctly or replace the batteries with new ones if necessary.

Was a remote control button pressed for more than 30
seconds? 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). When the button is released, normal remote control
operation resumes. This can prevent the batteries from running down accidentally because Sleep Mode
operates when the remote control is stored in a bag or if an object is placed on top of it.
