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.
