Otherwise, the transceiver's keys, switches and controllers may become unusable due to salt crystallization. ❍ USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. “MAYDAY MAYDAY MAYDAY.” 2. “THIS IS ...........................
FOREWORD FEATURES Thank you for purchasing this Icom radio. The IC-M33 VHF MARINE TRANSCEIVER is designed and built with Icom’s state of the art technology and craftsmanship. With proper care this radio should provide you with years of trouble-free operation. Built tough to withstand the punishing marine environment, the IC-M33’s submersible construction meets IPX7 of the corresponding International Standard IEC 60529 (2001) while using BP-251 (option) or BP-252.
PRECAUTIONS 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 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 away from the lips and the transceiver is vertical. NEVER connect the transceiver to a power source other than the BP-251 (option) or BP-252.

4 BASIC OPERATION ■ Channel selection IMPORTANT!: Prior to using the transceiver for the first time, the battery pack must be fully charged for optimum life and operation. To avoid damage to the transceiver, turn the power OFF while charging. D Channel 16 Channel 16 is the distress and safety channel. It used for establishing initial contact with a station and for emergency communications. Channel 16 is monitored during both Dualwatch and Tri-watch. While standing by, you must monitor Channel 16.
BASIC OPERATION 4 D U.S.A., International and ATIS channels The IC-M33 is pre-programmed with U.S.A.*, International and ATIS† channels. These channel groups may be specified for the operating area. 4 *U.K. version only; German and Holland versions only † q Push [CH] to select a regular channel. w Push and hold [CH] for 1 sec. to change the channel group. Repeat to advance to the next group. • U.S.A., International and ATIS channel groups can be selected in sequence. Y]/[Z Z] to select a channel.
