RF Exposure Compliance and Control Guidelines and Operating
Instructions
To control exposure to yourself and others and to ensure compliance with the RF expo-
sure limits, always adhere to the following procedures.

 User awareness instructions should accompany device when transferred to other us-
ers.
 DO NOT use this device if the operational requirements described herein are not
met.

nstruCtions
 Transmit no more than the rated duty factor of 50 % of the time. To transmit
(talk), push the Push-To-Talk (PTT) button or, for radios equipped with VOX, speak
into the microphone. The red will illuminate when the radio is transmitting. To re-
ceive calls, release the PTT button, or, for radios equipped with VOX, stop talking.
The red LED will extinguish when the radio stops transmitting. Transmitting 50 %
of the time, or less, is important because this radio generates measurable RF energy
exposure (in terms of measuring for standards compliance) only when transmitting.
 Transmit only when people outside the vehicle are at least the recommended
minimum lateral distance away, as shown in Table below, from the body of a
vehicle with a properly installed antenna. This separation distance will ensure
that there is sufficient distance from a properly installed (according to installation
instructions) externally-mounted antenna to satisfy the RF exposure requirements in
the applicable standards listed above.
 Antennas used for this transmitter must not exceed an antenna gain of 0 dBd.
NOTE: Table below lists the recommended lateral distance for people in an uncon-
trolled environment from the body of a vehicle with a properly installed transmit-
ting antenna (i.e., monopoles over a ground plane) with gain equal to or less than
the specified maximum gain.
FCC RF Exposure Requirements
IC RF Exposure Requirements
 When a mobile radio is used in conjunction with another co-located transmitter such
as a Vehicular Repeater, it is the vehicle operator's responsibility to take appropriate
steps to keep bystanders at the required separation distance from the vehicle to en-
sure compliance with the FCC's RF energy exposure limits for the general popula-
tion. See the co-located transmitter's user manual for more details.
NOTE: If you are not sure of the rated power of your radio, contact your sales rep-
resentative or dealer and supply the radio model number found on the radio model
