FCC EXPOSURE STATEMENTS
WARNINGS
The FCC has adopted a safety standard for human exposure to RF energy. Proper operation
of this radio under normal conditions results in user exposure to RF energy below the
Occupational Safety and Health Act and Federal Communication Commission limits.
Mandatory Safety Instructions to Installers and Users:
This radio is NOT approved for use by the general population in an uncontrolled environment.
This radio is restricted to occupational use and work related operations only. Radio operators
must have the knowledge to control their exposure conditions and the exposure conditions of
bystanders and/or passengers to satisfy the lower exposure limit allowed for General
Population.
To comply with FCC RF exposure limits, DO NOT operate the transmitter of this mobile radio
when a person outside the vehicle is within 22 inches (56 centimeters) of the antenna.
The antenna supplied by the manufacturer or radio dealer must be mounted at a location such
that during radio transmission, no person or persons can come closer than the above indicated
minimum safe distance to the antenna, i.e. 22 inches. To comply with current FCC RF
exposure limits, the antenna must be installed at or exceeding the minimum safe distance
stated above, and in accordance with the requirements of the antenna manufacturer or
supplier.
Vehicle Installation Instructions:
The antenna used for this transmitter must be mounted on the center of the roof ONLY and
must be installed in vehicle having the following characteristics in order to prevent bystanders
and passengers from being exposed to levels exceeding the limits for General
Population/Uncontrolled Exposure environment:
1. All passengers must be sitting under a solid metal roof.
2. For rear deck trunk and roof top installations, the antenna must be located at least 22
inches (56 centimeters) away from rear-seat passengers and bystanders in order to
comply with the FCC RF exposure requirements.
DO NOT operate the radio without the proper antenna installed. Do not substitute any antenna
for the one supplied or recommended by the manufacturer or radio dealer. Antennas used for
this transmitter must not exceed an antenna gain of 3 dBi. By not following the antenna
recommendations you may be exposing person(s) to excess radio frequency radiation. You
may contact your radio dealer or the manufacturer for further instructions.
DO NOT transmit more than 50% of total radio use time (50% duty cycle). Transmitting for
more than 50% of the time can cause FCC RF exposure compliance requirements to be
exceeded. This radio is transmitting whenever the Transmit/Receive LED is red. Pressing the
PTT switch on the side of the microphone normally causes the radio to transmit.
The preceding information is provided to make you aware of RF exposure
and how to ensure that this radio is operated within FCC RF exposure
limits.
You, as the qualified end-user of this radio device must control the exposure conditions of
bystanders to ensure the minimum separation distance, stated above for satisfying FCC RF
exposure compliance, is maintained between the antenna and nearby persons. Transmit only
when all person(s) are at least the minimum distance from the properly installed, externally
mounted antenna.
