Remote control functions can be selected from 3 settings. 
These can be selected with “MIC SIMPLE MODE” in set 
mode.

The HM-75A has a lock switch on the backside to prevent 
accidental frequency changes, etc.
 Be sure to turn power OFF when plugging the HM-75A/
unplugging OPC-1797 to/from the [DATA/SP/MIC] jack.
