1.2.1 RF Exposure Guidelines
To ensu
re that exposure to RF electromagnetic energy is within the
EU/AU/FCC/IC
allowable limits for occupational use, always adhere to the
following guidelines:
• DO NOT operate the radio without a proper antenna attached, as this may damage the radio
and may also cause the FCC RF exposure limits to be exceeded. A proper antenna is the
antenna supplied with this radio by L3Harris or an antenna specifically authorized by L3Harris
for use with this radio. (Refer to Table 4-1.)
• 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 appears in the display. The radio
will transmit by pressing the “PTT” (Push-To-Talk) button.
• ALWAYS transmit using low power when possible. In addition to conserving battery charge,
low power can reduce RF exposure.
• ALWAYS use L3Harris authorized accessories (antennas, batteries, belt clips, speaker/mics,
etc.). Use of unauthorized accessories may cause the FCC Occupational/Controlled Exposure
RF compliance requirements to be exceeded. (Refer to Table 1-1.)
• As noted in Table 1-1, ALWAYS keep the housing of the transmitter AT LEAST 0.47 inches
(1.2 cm) from the body and at least 0.98 in (2.5 cm) from the face when transmitting to ensure
EU/AU/FCC/IC RF exposure compliance requirements are not exceeded. However, to provide
the best sound quality to the recipients of your transmission, L3Harris recommends you hold
the microphone at least 2 in (5 cm) from mouth, and slightly off to one side.
• Refer to Standard EN 62311:2008.
