When I program the A7, all the lights that are supposed to come on/blink do so in the correct sequence, but no success after.
For example: I set the A7 to learn, press V+, then press & hold V+ on the AVR's remote. The A7 flashes green twice, indicating (supposedly) that it has learnt the signal.
but when it comes out of programming mode, V+ still tries to increase the volume on the decoder and not the AVR.
Sounds like you're maybe trying to program buttons that can't be programed, try re-reading the manual. Or it just is a code that doesn't work, despite claiming to, that can happen sometimes.
I can't help further
