FOREWORD FEATURES Thank you for purchasing this Icom radio. The IC-M71 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. SAVE THIS INSTRUCTION MANUAL—This instruction manual contains important operating instructions for the IC-M71.
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 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-245.
