OPERATING RULES

D Priorities

Read all rules and regulations pertaining to priorities and keep an up-to-date copy handy. Safety and distress calls take priority over all others. You must monitor Channel 16 when you are not operating on another channel. False or fraudulent distress calls are prohibited under law.
(2) OPERATORS LICENSE A restricted Radiotelephone Operator Permit is the license most often held by small vessel radio operators when a radio is not required for safety purposes. The Restricted Radiotelephone Operator Permit must be posted near the transceiver or be kept with the operator. Only a licensed radio operator may operate a transceiver. However, non-licensed individuals may talk over a transceiver if a licensed operator starts, supervises, ends the call and makes the necessary log entries. A current copy of the applicable government rules and regulations is only required to be on hand for vessels in which a radio telephone is compulsory. However, even if you are not required to have these on hand it is your responsibility to be thoroughly acquainted with all pertinent rules and regulations.

D Privacy

Information overheard but not intended for you cannot lawfully be used in any way. Indecent or profane language is prohibited.

D Radio licenses

(1) SHIP STATION LICENSE When your craft is equipped with a VHF FM transceiver, you must have a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed. Inquire through your dealer or the appropriate government agency for a Ship-Radiotelephone license. This license includes the call sign which is your crafts identication for radio purposes.

SCAN OPERATION (except Dutch versions)

I Scan types

Scanning is an efcient way to quickly locate signals over a wide frequency range. The transceiver has a priority scan setting and normal scan setting. In addition, the Auto scan function is also available for scanning. This function can be activated simultaneously, depending on the settings on the SET mode. (p. 18) Set the TAG channels (scanned channel) before scanning. Clear those TAG channels which are not needed or inconveniently stop scanning, such as digital communications. Choose priority or normal scan on the SET mode. (p. 18)

PRIORITY SCAN

CH 01 CH 02

NORMAL SCAN

Priority scan searches through all TAG channels in sequence while monitoring Channel 16. When a signal is detected on Channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, scan becomes dualwatch until the signal disappears.
Normal scan, like priority scan, searches through all TAG channels in sequence. However, unlike priority scan, Channel 16 is not checked unless Channel 16 is set as a TAG channel.

BATTERY CHARGING

I Battery cautions

Misuse of Lithium-ion batteries may result in the following hazards: smoke, re, or battery rupture. Misuse can also cause other battery damage or degradation of battery performance.
R DANGER! Use and charge only specified Icom battery pack with Icom transceiver. Only Icom battery pack is tested and approved for use with Icom transceiver. Using thirdparty or counterfeit battery packs may cause smoke, re, or cause the battery to burst.

R DANGER! DO NOT expose the battery to rain, snow, seawater, or any other liquids. Do not charge or use a wet battery. If the battery gets wet, be sure to wipe it dry before using. The battery by itself is not waterproof. R DANGER! NEVER incinerate a used battery pack since internal battery gas may cause a rupture or explosion. R DANGER! NEVER solder the battery terminals, or NEVER modify the battery pack. This may cause heat generation, and the battery may rupture, emit smoke or catch re. R DANGER! Use the battery only with the transceiver for which it is specified. Never use a battery with any other equipment, or for any purpose that is not specied in this instruction manual. R DANGER! If fluid from inside the battery gets in your eyes, blindness can result. Rinse your eyes with clean water, without rubbing them, and see a doctor immediately. WARNING! Immediately stop using the battery if it emits an abnormal odor, heats up, or is discolored or deformed. If any of these conditions occur, contact your Icom dealer or distributor. WARNING! Immediately wash, using clean water, any part of the body that comes into contact with uid from inside the battery.

D Battery caution

R DANGER! DO NOT hammer or otherwise impact the battery. Do not use the battery if it has been severely impacted or dropped, or if the battery has been subjected to heavy pressure. Battery damage may not be visible on the outside of the case. Even if the surface of the battery does not show cracks or any other damage, the cells inside the battery may rupture or catch re. R DANGER! NEVER use or leave battery pack in areas with temperatures above +60C. High temperature buildup in the battery, such as could occur near res or stoves, inside a sun-heated car, or by setting the battery in direct sunlight may cause the battery to rupture or catch fire. Excessive temperatures may also degrade battery performance or shorten battery life.

Page 24

WARNING! NEVER put the battery in a microwave oven, high-pressure container, or in an induction heating cooker. This could cause overheating, a re, or cause the battery to rupture. CAUTION! Always use the battery within the specied temperature range for the transceiver (15C to +55C) and the battery itself (20C to +60C). Using the battery out of its specied temperature range will reduce the batterys performance and battery life. Please note that the specied temperature range of the battery may exceed that of the transceiver. In such cases, the transceiver may not work properly because it is out of its operating temperature range. CAUTION! Shorter battery life could occur if the battery is left fully charged, completely discharged, or in an excessive temperature environment (above +45C) for an extended period of time. If the battery must be left unused for a long time, it must be detached from the radio after discharging. You may use the battery until the battery indicator shows half-capacity, then keep it safely in a cool dry place with the temperature between 20C to +25C.

D Charging caution

R DANGER! NEVER charge the battery pack in areas with extremely high temperatures, such as near res or stoves, inside a sun-heated car, or in direct sunlight. In such environments, the safety/protection circuit in the battery will activate, causing the battery to stop charging. WARNING! DO NOT charge or leave the battery in the battery charger beyond the specified time for charging. If the battery is not completely charged by the specied time, stop charging and remove the battery from the battery charger. Continuing to charge the battery beyond the specied time limit may cause a re, overheating, or the battery may rupture. WARNING! NEVER insert the battery and transceiver (battery attached to the transceiver) into the charger if it is wet or soiled. This could corrode the battery charger terminals or damage the charger. The charger is not waterproof. CAUTION! DO NOT charge the battery outside of the specied temperature range: 0C to +45C. Icom recommends charging the battery at +20C. The battery may heat up or rupture if charged out of the specified temperature range. Additionally, battery performance or battery life may be reduced.
