CLEAN THE TRANSCEIVER THOROUGHLY WITH FRESH WATER after exposure to saltwater, and dry it before operation. Otherwise, the transceiver’s keys, switches and controllers may become inoperable due to salt crystallization. ❍ USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. “MAYDAY MAYDAY MAYDAY.
IC-M72_1.qxd 06.1.11 18:19 Page iii (1,1) New2001 FOREWORD FEATURES Thank you for purchasing this Icom radio. The IC-M72 VHF MARINE TRANSCEIVER is designed and built with Icom’s state of the art technology and craftsmanship. With proper care this product should provide you with years of trouble-free operation. IMPORTANT READ ALL INSTRUCTIONS carefully and com- pletely before using the transceiver.
IC-M72_1.qxd 06.1.11 18:19 Page iv (1,1) New2001 PRECAUTION RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock. RWARNING! NEVER hold the transceiver so that the antenna is closer than 2.5 cm (1 inch) from exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 inches) away from the lips and the transceiver is vertical.
