Recommendations for Marine Communication

AVOID using or storing the radio at temperatures below -4°F (-20°C) or above 140°F (60°C).

NEVER connect the transceiver to DC power greater than 16 volts or to any DC source with reversed polarity. Doing so will damage the transceiver.

DO NOT cut the power cables attached to the transceiver. Improper reconnection with reversed polarity will damage the transceiver.

POSITION your radio, external speakers and cables at least 3 ft (0,9 m) away from your vessel’s magnetic navigation compass. CHECK your compass before and after installation to be sure that it has not introduced any deviation.

DO NOT attempt to service any internal parts yourself. Have any necessary service performed by a qualified technician.

DO NOT drop the transceiver or microphone/speaker. Doing so may crack the case or damage a waterproof seal. Once these items have been dropped, the original waterproofing cannot be guaranteed.

DO NOT use chemicals or solvents such as mineral spirits and alcohol to clean your radio. They may damage the case surfaces.

Changes or modifications to your radio MAY VOID its compliance with FCC (Federal Communication Commission) rules and make it illegal to use.

Recommendations for Marine Communication

•

The frequencies your radio uses are set aside to enhance safety afloat and for vessel navigation and operational messages over a range suitable for near-shore voyages. If the 25 watt maximum output of your radio is not sufficient for the distances you travel from the coast, consider installing a more powerful radio such as HF single-side band or satellite radio for your vessel.

The U.S. Coast Guard does not endorse cellular telephones as substitutes for marine radios. They generally cannot communicate with rescue vessels and, if you make a distress call on a cellular telephone, only the party you call will be able to hear you. Additionally, cellular telephones may have limited coverage over water and can be hard to locate. If you do not know where you are, the Coast Guard will have difficulty finding you if you are using a cellular telephone.

However, cellular telephones can have a place onboard where cellular coverage is available — to allow social conversations and keep the marine frequencies uncluttered and available for their intended use.
