SAFETY TRAINING INFORMATION
Your Icom radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as Occupational Use Only, meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is W ARN ING NOT intended for use by the General Population in an uncontrolled environment. 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 specied may result in RF exposure levels exceeding the FCC requirements for wireless RF exposure.; Belt Clip (MB86/103), Rechargeable Ni-MH Battery Pack (BP-210N) and Alkaline Battery Case (BP-208N). 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 also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or antenna specically 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 appears on the function display. 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 page 31 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 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/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 and blasting sites.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure.

I Duplex operation

NEVER incinerate used battery packs. Internal battery gas may cause an explosion. NEVER immerse battery pack in water. If the battery pack
becomes wet, be sure to wipe it dry immediately (particularly the battery terminals BEFORE attaching it to the transceiver.
NEVER short the terminals of the battery pack. Also, current may ow into nearby metal objects, such as a necklace, etc. Therefore, be careful when carrying with, or placing near metal objects, carrying in handbags, etc. If your battery pack seem to have no capacity even after being charged, completely discharge them by leaving the power ON overnight. Then, fully charge the battery pack again. If the batteries still do not retain a charge (or very little), new battery pack must be purchased. Turn the transceiver power OFF when charging the battery pack. Otherwise, the battery pack may not fully charge or charge properly.
D Recycling information (U.S.A. only)
The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the end of its life, under various state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Call 1-800822-8837 for battery recycling options in your area or contact your dealer.
BATTERY PACKS D Regular charging
q Attach the battery pack to the transceiver. w Be sure to turn the transceiver power OFF. e Connect the Wall charger or optional cable (CP-20) as shown below. r Charging the battery pack approx. 8 hours, depending on the remaining power condition. DO NOT charge BP-210N more than 12 hours. Otherwise, BP-210N will be damaged. BP-210N must be charged for 812 hours only.
