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-broadcasting

frequency. Point the remote control towards it, push any button and listen. If the sound from the radio flutters, 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.
