FCC RF EXPOSURE
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 130 centimeters (51 inches) for VHF or 93 centimeters (37 inches) for UHF, 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. 130 or 93 cm. 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:
All passengers must be sitting under a solid metal roof.
Rooftop width must be at least 76 inches OR the edges of the physical boundary of the vehicle must
be at least 76 inches apart.
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. The antenna gain must not exceed
0 dBd. 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 TX icon is displayed on the LCD. Pressing the PTT switch on the side of the
microphone normally causes the radio to transmit.
Note: 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.
IMPORTANT SAFETY INFORMATION
CAUTIONS
The antenna connector must be snugly tightened to maintain proper electrical connection and
moisture resistance.
Equipment must be grounded according to Midland Radio Corporation installation instructions for safe
operation.
Equipment should be serviced only by a qualified technician. Refer to radio service manual for
additional information on installation and safety precautions.
WARNING!
! DO NOT allow the antenna to touch or come in very close proximity with the eyes, face, or any
exposed body parts while the radio is transmitting
! DO NOT operate the radio in explosive or flammable atmospheres. The transmitted radio energy could
trigger blasting caps or cause an explosion.
! DO NOT allow children to operate or play with this radio.
Note: The above warning list is not intended to include all
hazards that may be encountered when using this radio.
