Use a digital camera to test your Apple Remote. 3.
If you have a digital camera or DV camera with an LCD display, you can use it to see if your
Apple Remote is emitting a signal. Infrared beams are invisible to the human eye, but most
digital cameras and video cameras use Charged-Coupled Device (CCD) chips or image
sensors that are sensitive to infrared light.
To use a camera to test your Apple Remote, follow these steps:
• Turn on your digital camera or DV camera and remove any lens cover.
• Point your Apple Remote toward the display latch button.
• Press and hold the Menu button on the remote while looking at your camera’s LCD display.
• If you see a faint blinking light coming from the Apple Remote in the camera’s LCD, then
the remote is working properly.
• If you don’t see any blinking light in the camera’s LCD, replace the battery in your Apple
Remote and then test it again with your computer.
