Remote control defective? How to check the functionality
It is not always so easy to find out whether your remote control is really defective or still working. The remote control sends infrared signals to the TV. We show you how you can check this without high-tech equipment.
Remote control defective? How to find out:
The sensor of every digital camera detects the infrared light of wavelengths 940 to 950 nanometers. You can therefore easily carry out a function test with a cell phone camera:
- You just press a button on the remote control and hold the camera on it at the same time - release - done.
- The point of light can be clearly seen on the shot when the remote control is still sending a signal.
- Alternatively, the live preview on the LCD of a common digital camera or camcorder can be misused.
- On the other hand, recording with a good digital camera is not sensible: it often triggers so quickly that the pulsed signal is not captured on the image.
Tip: You can also temporarily use your iPhone or HTC One as a remote control.
