Just bought one, all new to me. Question, does the on off switch control volume? Mine clicks on but does not rotate like a volume switch. Running volume up with handheld brings volume up some but about 30 ft. away I just barely hear it
Check out the above link. It shows a sound up arrow and a sound down arrow in the middle of the remote.
Position mouse over image of the remote to zoom the image bigger..
Figured it out, two things. Written description is not exact same as on hand held, but big problem was new unused batteries were weak, put in high end and everything seems to be working
