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 the
specified gain by the manufacturer declared.
• DO NOT transmit for more than 50% of total radio use time, more than
50% of the time can cause RF exposure compliance requirements to
be exceeded.
• 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 electro-
magnetic radiation such as hospitals, aircraft, and blasting sites.
• Portable Device, this transmitter may operate with the antenna(s)
documented in this filing in Push-to-Talk and body-worn configurations.
RF exposure compliance is limited to the specific belt-clip and accessory
configurations as documented in this filing and the separation distance
between user and the device or its antenna shall be at least 2.5 cm.
• Mobile Device, during operation, the separation distance between user
and the antenna subjects to actual regulations, this separation distance
will ensure that there is sufficient distance from a properly installed
externally-mounted antenna to satisfy the RF exposure requirements.
• Occupational/Controlled Radio, this radio is designed for and classified
as "Occupational/Controlled Use Only", meaning it must be used only
