[Hotspring Grandee 2020 remote not working]

My remote does not seem to work.  If I press a function nothing happens, but if the function is pressed on the docking station the remote will change screens to correspond this the dock button pressed.  I seems that the remote will receive signals from the tub, but the tub does not seem to get signals from the remote.  It has worked on and off and i changed the Channel and restarted the remote.  Any ideas?
