Activote won't work red button comes on only
We had two activotes that stopped registering the answer. Batteries were replaced in both, one works fine now the other as soon as the battery pack is slid in the red light lights up steady and remains lit for 30sec or so before going out. It won't send votes to the promethean and removing to re-register did not work either as it won't register. Holding the flame button only the red button lights up.
