Question about Universal Remote MX900 PC-Programmable IR&IF-Handheld Remote 418MHZ
How do you clean the contacts?
Remove the batteries and any screws you may find there and anywhere else on the case. The front and back halves of the case will have clips holding them together that can be released by inserting a thin tool into the seam separating the case halves, pushing in and prying apart as you work your way around the case. Once the case separates, lay the remote face down on a flat surface so that any individual buttons will not fall out. Remove any screws that may be holding the circuit board and remove it. The contact surface of the rubber buttons is coated with a conductive surface and can be cleaned with alcohol or contact cleaner. The contact area of the circuit board can be cleaned in the same manner or rubbed with a pencil eraser. Reassemble and give it a try before you snap the case together. If all else fails I've had success cutting small pieces of aluminum foil and gluing it to the contact area of the rubber buttons.
