I recently replaced the lithium battery in my 2300 as pre-set sound settings and radio stations were lost when it was dis-connected from the mains. This cured the problem but now it won't respond to the remote control unit correctly. Some functions work OK, eg Sat and TV will select and display on the units' display screen but CD and Radio do not respond at all. All functions work manually from the units keypad though!
Any thoughts/help gratefully received.
