And, of course,  always at the wrong moment.

If your remote control doesn’t function anymore, it is probably a matter of changing the batteries with good quality, the same type of batteries. Sometimes that doesn’t work, and you need to investigate a little more, so:

1. Check the batteries in use; if you notice any proof of leakage (wet or dry), forget these batteries.
2. Check the battery contacts in the remote and clean them if you feel/see that this is necessary. Also, using contact-cleaner, contact-enhancer is a good idea.
3. If new, good-quality batteries make the remote function again, you are done!
4. If the remote with cleaned contacts ánd fresh full batteries still does not function, it might be that the remote is really broken. How to test? Just do like you want to take a picture of the eye of your remote, and on the screen of your digital camera, you will see the LED light up (if the remote functions) once you press a button on the remote. If the remote is broken, you won’t see the LED in the picture.
5. If you do see the LED light up in the picture, but your equipment does not react, then it might be that the carrier of the signal is active, but the necessary signal isn’t. And worse, if the receiver is broken, the only thing you can do is bring the equipment to your specialist dealer.
6. And … last but not least … never use chargeable batteries in your remotes.
