this radio by the manufacturer or an antenna specifically authorized by the manufacturer
for use with this radio.
• DO NOT transmit for more than 50% of total radio use time ("50% duty cycle").
Transmitting more than 50% of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is transmitting when the "TX indicator" lights red.
You can cause the radio to transmit by pressing the "PTT" switch.
• ALWAYS use BAOFENG authorized accessories (antennas, batteries, belt clips,
speaker/mics, etc). Use of unauthorized accessories can cause the FCC RF exposure
compliance requirements to be exceeded. Body-worn operations are restricted to
belt-clips, holsters or similar accessories that have no metallic component in the assembly
and that provide at least 1.5 cm separation between the device, including its antenna, and
the user's body. To provide the recipients of your transmission the best sound quality, hold
the antenna at least 5 cm (2 inches) from mouth, and slightly off to one side. The
information listed above provides the user with the information needed to make him or her
aware of RF exposure, and what to do to assure that this radio operates within the FCC
RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, your BAOFENG 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.
This device complies with Part 90 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 except any interference received, including interference that may cause
undesired operation.
