Easy waterproof operation... manually or by remote! The IC-M502, with its standard 4" X 6" front panel, will easily blend into your cabin console or dashboard. The generous front panel provides large function switches and a wide LCD. With full dot matrix characters, information can be easily read under any lighting condition. By adding the new, optional COMMANDMIC (HM-127) all available functions of the IC-M502 (except DSC operation) can be controlled from remote locations, such as from the deck or flybridge. Plus, the COMMANDMIC doubles as an intercom. Click on the small image to get a large picture of the IC-M502.
