Important Information
Warning:
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may
cause undesired operation
Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
For a Class B digital device or peripheral, the instructions furnished to the user
shall include the following or similar statement, placed in a prominent location in
the text of the manual:
NOTE: 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 radiate 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 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 into an outlet on a circuit different from that to which the
receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.

Important Information
This radio is designed for and classified as “Occupational/Controlled Use Only”,
meaning it must be
used only during the course of employment by individuals aware of the hazards, and the
ways to minimize
such hazards; NOT intended for use in an General population/uncontrolled environment
–
DO NOT operate the radio without a proper antenna attached, as this may damage
the radio and may
also cause you to exceed RF exposure limits. A proper antenna is the antenna supplied
with this radio by
the manufacturer or an antenna specifically authorized by the manufacturer for use with
this radio, and the
antenna gain shall not exceed XdBi by the manufacturer declared.
–
DO NOT transmit for more than 100% of total radio use time, more than 100% of the
time can cause RF
exposure compliance requirements to be exceeded.
–
During operation, the separation distance between user and the antenna shall be at
least XXcm, this
separation distance will ensure that there is sufficient distance from a properly installed
externally-mounted antenna to satisfy the RF exposure requirements
–
During transmissions, your radio generates RF energy that can possibly cause
interference with other
devices or systems. To avoid such interference, turn off the radio in areas where signs
are posted to do
so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic
radiation such as
hospitals, aircraft, and blasting sites
