Preset frequencies act similar to a video tuner Tune Ring, after the last preset is selected (Preset 9), the next
Preset Up command will start at the lowest Preset (0). While the 232-FMA has only audio outputs at present,
we have kept the Mute A/V commands to be consistent with programming and operation for the 232-STA and
232-MTA TV Tuners.
