iYour Icom radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as “General Population Use” in an uncontrolled environment.This radio has been evaluated for compliance at the distance of 2.5 cm (1 inch) with the FCC RF exposure limits for “Gen-eral Population Use”. In addition, your Icom radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: • FCC OET Bulletin 65 Edition 01-01 Supplement C, Evaluating Compli-ance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. • American National Standards Institute (C95.1-2005), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. • American National Standards Institute (C95.3-2002), IEEE Recom-mended Practice for the Measurement of Potentially Hazardous Electro-magnetic Fields– RF and Microwave. • The following accessories are authorized for use with this product. Use of accessories other than those specified may result in RF exposure levels exceeding the FCC requirements for wireless RF exposure.; Belt Clip (MB-109), Rechargeable Li-Ion Battery Pack (BP-252) and Alkaline Bat-tery Case (BP-251).To ensure that your expose to RF electromagnetic en-ergy is within the FCC allowable limits for general popu-lation use, always adhere to the following guidelines: • DO NOT operate the radio without a proper antenna attached, as this may damaged the radio and may also cause you to exceed FCC RF ex-posure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or antenna specifically authorized by the manufacturer for use with this radio. • DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more than 50% of the time can cause FCC RF expo-sure compliance requirements to be exceeded. The radio is transmitting when the “transmit indicator” appears on the LCD. You can cause the radio to transmit by pressing the “PTT” switch. • ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and only use the Icom belt-clips which are listed on p. 28 when attaching the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the re-cipients of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and slightly off to one side.The information listed above provides the user with the information needed to make him or her aware of RF exposure, and what to do to assure that this radio operates with the FCC RF exposure limits of this radio.Electromagnetic Interference/CompatibilityDuring transmissions, your Icom radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites.iSAFETY TRAINING INFORMATIONW AR N IN GC AU T IO N
iiIN CASE OF EMERGENCY RECOMMENDATIONIf your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on Channel 16.❍ USING CHANNEL 16DISTRESS CALL PROCEDURE1. “MAYDAY MAYDAY MAYDAY.”2. “THIS IS ……………… ” (name of vessel)3. Your call sign or other indication of the ves-sel.4. “LOCATED AT …………… ” (your position)5. The nature of the distress and assistance required.6. Any other information which might facilitate the rescue.CLEAN THE TRANSCEIVER THOROUGHLY WITH FRESH WATER after exposure to saltwater, and dry it before opera-tion. Otherwise, the transceiver's keys, switches and control-lers may become unusable due to salt crystallization.NOTE: DO NOT wash the transceiver in water if there is any reason to suspect the waterproof protection may not be ef-fective.

FOREWORDThank you for purchasing this Icom radio. The IC-M36 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.IMPORTANTREAD ALL INSTRUCTIONS carefully and com-pletely before using the transceiver.SAVE THIS INSTRUCTION MANUAL—This instruction manual contains important operating instructions for the IC-M36.EXPLICIT DEFINITIONSWORD DEFINITIONRWARNING Personal injury, fire hazard or electric shock may occur.CAUTION Equipment damage may occur.NOTEIf disregarded, inconvenience only. No risk of personal injury, fire or electric shock.FEATURES☞ Floating on water The transceiver floats on fresh or salt water even when the supplied acces-sories are attached. • When a third-party battery pack, strap, antenna, etc. is used, it may sink. • The battery contacts may be prone to rust if the transceiver is kept floating on the water.☞ Clear voice boost The transceiver has the noise detection function which enables automatic volume adjustment and the volume loud function that enables you to maximize the volume level instantly to provide clear communication in the noisy marine environments.☞ Noise cancelling microphone The sub-microphone on the rear panel inverts the phase and cancels out the ambient noise from the main micro-phone. As a result, the transceiver can reduce the influ-ence of the background noise (particularly treble noise) on the transmitted signal. • The noise cancellation can produce no effect according to con-ditions such as loudness and type of noise, or the position and distance between the noise source and the microphone, etc. • The noise cancellation does not work when an optional exter-nal speaker-microphone is connected. iii
ivRWARNING! 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 transmit-ting. The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 inches) away from the lips and the trans-ceiver is vertical.NEVER connect the transceiver to a power source other than the BP-251 (option) or BP-252. Such a connection will ruin the transceiver.DO NOT use or place the transceiver in direct sunlight or in areas with temperatures below –20°C (–4°F) or above +60°C (+140°F).KEEP the transceiver out of the reach of children.KEEP the transceiver at least 0.9 meters (3.0 ft) away from your vessel’s magnetic navigation compass.BE CAREFUL! The transceiver’s right-side panel will become hot when operating continuously for long periods.BE CAREFUL! The transceiver meets IPX7* require-ments for waterproof protection. However, once the trans-ceiver has been dropped, waterproof protection cannot be guaranteed because of possible damage to the transceiver's case or the waterproof seal.* Only when the BP-251 (option) or BP-252, flexible antenna, [SP MIC] cap is attached.MAKE SURE the flexible antenna and battery pack are securely attached to the transceiver, and that the antenna and battery pack are dry before attachment. Exposing the inside of the transceiver to water will result in serious dam-age to the transceiver.After exposure to water, clean the battery contacts thor-oughly with fresh water and dry them completely to remove any water or salt residue.For U.S.A. onlyCAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations.
