FCC Statement

INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY THE FCC

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection

against harmful interference in a residential installation. This equipment generates, uses and can

generate radio frequency energy and, if not installed and used in accordance with the instructions,

may cause harmful interference to radio communications. However, there is no guarantee that the

interference will not occur in a particular installation. If this equipment does cause harmful

interference to radio or television reception, which can be determined by turning the equipment

off and on, the user is encouraged to try to correct the interference by one or more of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.

• Consult the dealer for technic

FCC WARNING

This equipment generates or uses radio frequency energy. Changes or modifications to this

equipment may cause harmful interference unless the modifications are expressly approved

by the party responsible/Iradio Electronics Co., Ltd. The user could lose the authority to operate

this equipment if an unauthorizedchange or modification is made.

This Iradio transceiver has been tested and complies with the standards listed below, in regards

to Radio Frequency (RF) energy and electromagnetic energy (EME) generated by the transceiver.

• FCC 47 CFR 1.1307, 1.1310 & 1.1093 RF exposure limits for Occupational Use Only. RF

Exposure limits adopted by the FCC are generally based on recommendations from the National

Council on Radiation Protection and Measurements & the American National Standards Institute.

• American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers

(IEEE) C95.1: 2005

The following list provides you with the information required to ensure that you are aware of RF

exposure and of how to operate this transceiver so that the FCC RF exposure limitations are not

exceeded.

• While transmitting (holding the PTT switch or speaking with VOX enabled), always keep the

antenna and the radio at least 2.5cm (1 inch) from your body or face, as well as from any bystanders.

• Do not transmit for more than 50% of the total transceiver use time; transmitting over 50% of

the total use time may exceed the limits in accordance to the FCC RF exposure requirements.

Nominal transceiver operation is 5% transmission time, 5% reception time, and 90% stand-by time.

• Use only the specified antenna for this transceiver; this may be either the antenna provided with

the transceiver or another antenna authorized by Iradio. Use only Iradio authorized accessories

(antennas, battery packs, belt clips, Speaker/Mics or headsets etc.): When worn on the body,

always place the radio in a Iradio recommended clip or carrying case meant for this product.

The use of other than recommended or approved body-worn accessories may result in RF exposure

levels which exceed the FCC’s occupational/controlled environment RF exposure limits.



To control your exposure and ensure compliance with the occupational/controlled environment exposure

limits always adhere to the following procedures.

Guidelines:

Do not remove the RF Exposure Label from the device.

User awareness instructions should accompany device when transferred to other users.

Do not use this device if the operational requirements described herein are not met.

• Use only the specified antenna for this transceiver; this
