SAFETY TRAINING INFORMATION

W AR N IN G

Your Icom radio generates RF electromagnetic energy during transmit mode.

This radio has been evaluated for compliance at the distance of 2.5 cm with the FCC RF exposure limits for “Occupational

Use Only”. 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 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.

• American National Standards Institute (C95.1-1992), IEEE Standard for

Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.

• American National Standards Institute (C95.3-1992), IEEE Recommended

Practice for the Measurement of Potentially Hazardous Electromagnetic

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-

86, MB-103), Rechargeable Li-Ion Battery Pack (BP-245), Speaker-microphone (HM-125), Headset with headset adapter (HS-94, HS-95, HS-97 with OPC-1392).

To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational 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 exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or an 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 exposure compliance requirements to be exceeded. The radio is transmitting when the “TX indicator” lights. When the radio is turned ON, pressing the

“PTT” switch makes the radio transmit.

• ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and only use one of the belt clips listed on page 33 when attaching the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your transmission the best sound quality, hold the radio in an almost vertical position at least 5 cm (2 inches) from your mouth. The microphone is located next to the speaker, so you should “talk into the speaker”.

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 within FCC RF exposure limits.

Electromagnetic Interference/Compatibility

During 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.

• The VOX gain and VOX delay can be set on the SET mode. (p. 22)

• During scan, dual/tri-watch or on a transmission inhibited channel, the VOX function will not be activated.

■ AquaQuake water draining function

The IC-M72 uses a new technology to clear water away from the speaker grill: AquaQuake. AquaQuake helps drain water away from the speaker housing (water that might otherwise muffle the sound coming from the speaker) . The IC-M72 emits a vibrating noise when this function is being used.

➥ Push and hold both [16•9] and [H/L•LOCK].

• A low beep tone sounds for 9 sec. to drain water, regardless of

[VOL] control setting.

• The transceiver never accepts a key operation while the AquaQuake function is activated. And this function won’t be activated when an optional speaker-microphone or headset is connected.

■ Channel naming

The IC-M72 has a capability to assign up to 10-character channel names or comments for each operating channel, including each weather channel. This provides easy recognition of channel usage, or station names, etc.

When shipped from the factory, the IC-M72 is programmed with default names for each VHF marine channel. These defaults can be changed, if desired.

You may replace the factory-set opening comment with a comment of your own. The opening comment appears each time the IC-M72 is powered ON. The comment may be up to

16 characters long.

SCAN OPERATION

■ Scan types

Scanning is an efficient way to quickly locate signals over a wide frequency range. The transceiver has a priority scan setting and normal scan setting.

In addition, the “Weather alert” and “Auto scan” functions are also available for scanning. These functions can be activated simultaneously, depending on the settings on the SET mode.

(pgs. 18, 19)

PRIORITY SCAN

CH 01 CH 02

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)

NORMAL SCAN

CH 01 CH 02

WX* CH 16 CH 03

CH 05 CH 04

* Previously selected weather channel

when weather alert function is ON

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.

WX* CH 03

■ Battery cautions

Misuse of Lithium-ion batteries may result in the following hazards: smoke, fire, 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, fire, or cause the battery to burst.

• 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 fire.

• R DANGER! NEVER use or leave battery pack in areas with temperatures above +60˚C (+140˚F). High temperature buildup in the battery, such as could occur near fires 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.

• 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 fire.

• 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 specified 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 fluid from inside the battery.

BATTERY CHARGING

• WARNING! NEVER put the battery in a microwave oven, high-pressure container, or in an induction heating cooker.

This could cause overheating, a fire, or cause the battery to rupture.

• CAUTION! Always use the battery within the specified temperature range for the transceiver (–20˚C to +60˚C; –4˚F to

+140˚F) and the battery itself (–20˚C to +60˚C; –4˚F to

+140˚F). Using the battery out of its specified temperature range will reduce the battery’s performance and battery life.

Please note that the specified 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 +45˚C; +113˚F) 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 –20˚C to +25˚C (–4˚F to

+77˚F).

• R DANGER! NEVER charge the battery pack in areas with extremely high temperatures, such as near fires 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 specified time, stop charging and remove the battery from the battery charger.

Continuing to charge the battery beyond the specified time limit may cause a fire, 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 specified temperature range: ±0˚C to +45˚C (+32˚F to +113˚F).

Icom recommends charging the battery at +20˚C (+68˚F).

The battery may heat up or rupture if charged out of the specified temperature range. Additionally, battery performance or battery life may be reduced.

to your shirt or collar, etc.

■ Attachment

Insert the speaker-mic connector onto the [SP MIC] connector and carefully screw it tight, as shown in the diagram below. Be careful not to cross-thread the connection.

Set the triangle mark to the front side.

CAUTION: Attach the speakermicrophone’s connector securely to prevent accidental dropping, or water intrusion in the connector.

Detaching:

Pull up the cap in the direction of the arrow to detach it.

Attaching:

Attach the cap in the direction of the arrow completely.

NEVER immerse the connector in water. If the connector becomes wet, be sure to dry it BEFORE attaching it to the transceiver.

NOTE: The microphone is located at the top of the speaker-microphone, as shown in the diagram above. To maximize the readability of your transmitted signal (voice) , hold the microphone approx. 2.5 cm (1 inch) from your mouth, and speak in a normal voice level.

IMPORTANT: KEEP the transceiver’s [SP MIC] connector cap attached when the speaker-microphone is not in use.

Water will not get into the transceiver even if the cover is not attached; however, the terminals (pins) will become rusty, or the transceiver will function abnormally if the connector has become wet.
