Onassis

my remote control for my R-15PM has stopped working after a year - can the battery already be dead? if i remove the battery and put it back in, in the most cases it starts working for a short time again... sometimes i need to repeat this to get it working... I do not really need the control, but sadly its the only way to turn the speakers on :-( I dont want to buy a new battery finding out that the remote is the part thats not working (perhaps the battery contacts). And my mobile camera does not seem to be working with filming the remote lamp. I cannot see anything even if the remote is working.
