IR Signal Check
If the remote control is not working properly, you can use an AM
radio or digital camera (including a cellular phone with built-in
camera) to see if it is sending out an infrared signal.
• With an AM radio:
Tune the AM radio station to a non-

control towards it, push any button and
listen. If the sound from the radio  utters,
it is receiving the remote control’s infrared
signal.
• With a digital camera
(including built-in cell phone cameras):
Point a digital camera towards the remote control.
Push any button on the remote control and look
through the digital camera. If the infrared light
appears through the camera, the remote control is
working.
