Different models of ActiVote require specific ActivHubs or ActivBoards. Check the model number on the bottom of the ActiVote device.
PRM-AV2-01 ActiVotes use 866MHz/915MHz frequencies and should be registered to a 2nd Generation ActivBoard or a PRM-AH1-01 ActivHub.
PRM-AV3-01 ActiVotes use 2.4GHz frequency and should be registered to a PRM-AH2-01 ActivHub. Both carry the ActivAir symbol:
PRM-AV3-02 ActiVotes use 2.4GHz frequency and should be registered to a PRM-AH2-01 ActivHub. This ActiVote device does not carry the ActivAir symbol but can be recognised by its front colour buttons.
NB: PRM-AV3-01 ActiVotes that are diagnosed as faulty under Promethean’s warranty terms and conditions will be replaced with PRM-AV3-02 devices. The devices work in exactly the same way and the only difference is the front colour buttons.
