RADIO FREQUENCY ENERGY SAFETY INFORMATION
Your Xradio radio generates RF electromagnetic energy during
transmit mode. This radio is designed for and classified as
“Occupational 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. This radio is NOT intended for use by
the “General Population” in an uncontrolled environment.
This radio has been tested and complies with the FCC RF exposure limits for
“Occupational Use Only”. In addition, your XRADIO radio complies with the following
Standards and Guidelines with regard to RF energy and electromagnetic energy levels and
evaluation of such levels for exposure to humans:
■FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC
Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
■American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels
with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to
300 GHz.
■American National Standards Institute (C95.3-1992), IEEE Recommended Practice
for the Measurement of Potentially Hazardous Electromagnetic Fields– RF and Microwave.
■The following accessories are authorized for use with this product. Use of accessories
other than those (listed in the instruction) specified may result in RF exposure levels
exceeding the FCC requirements for wireless RF exposure.
To ensure that your expose to RF electromagnetic energy is within the
FCC allowable limits for occupational use, always adhere to the
following guidelines:
■DO NOT operate the radio without a proper antenna attached, as this may damaged
the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna
is the antenna supplied with this radio by the manufacturer or antenna specifically
authorized by the manufacturer for use with this radio.
■DO NOT transmits 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 keep the antenna at least 2.5 cm (1 inch) away from the body when

4
transmitting and only use the Xradio belt-clip which is listed in instructions when attaching
the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not
exceeded. To provide the recipients of your transmission the best sound quality, hold the
antenna at least 5 cm (2 inches) from your 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 as-sure that this radio operates with the
FCC RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, your XRADIO 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.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as consequence of
their employment provided those persons are fully aware of the potential for exposure and
can exercise control over their exposure.
OPERATING NOTES
■When transmitting with a portable radio, hold the radio in a vertical position with its
microphone 5 to 10 cm (2 to 4 inches) away from your mouth. Keep the antenna at least
2.5 cm (1 inch) from your head and body.
■If you wear a portable two-way radio on your body, ensure that the antenna is at least
2.5 centimeters (1 inch) from your body when transmitting.
PRECAUTIONS
WARNING! NEVER hold the transceiver so that the antenna is very close to, or touching
exposed parts of the body, especially the face or eyes, while transmitting. The transceiver
will perform best if the microphone is 5 to 10 cm (2 to 4 inches) away from the lips and the
transceiver is vertical.
WARNING! NEVER operate the transceiver with a headset or other audio accessories at
high volume levels.
CAUTION! NEVER short the terminals of the battery pack.
NEVER connect the transceiver to a power source other than the Battery listed below Such
a connection will ruin the transceiver.
DO NOT push the PTT when not actually desiring to transmit.

5
AV O I D u sing or placing the transceiver in direct sunlight or in areas with temperatures
below –30°C (–22°F) or above +60°C (+140°F). DO NOT modify the transceiver for any
reason.
MAKE SURE the flexible antenna and battery pack are securely attached to the
transceiver, and that the antenna and battery pack are dry before attachment. Exposing the
inside of the transceiver to water will result in serious damage to the transceiver.
BE CAREFUL! The series transceivers employ waterproof construction, which
corresponds to IPX7 of the international standard IEC 60529 (2001), 1 m depth for 30
minutes. However, once the transceiver has been dropped, waterproofing cannot be
guaranteed due to the fact that the transceiver may be cracked, or the waterproof seal
damaged, etc.
The use of non-XRADIO battery packs/chargers may impair transceiver performance and
invalidate the warranty.
FCC Notice Cautions.
Changes or Modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
