•
Always transmit using low power when possible. In addition to
conserving battery charge, low power can reduce RF exposure.
•
ALWAYS use M/A-COM 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.
•
As noted in Table 2-1, ALWAYS keep the device and its antenna AT
LEAST 1.1 cm (0.43 inches) from the body and at least 2.5 cm (1.00
inch) from the face when transmitting to ensure FCC RF exposure
compliance requirements are not exceeded. However, to provide the best
sound quality to the recipients of your transmission, M/A-COM
recommends you hold the microphone at least 5 cm (2 inches) from your
mouth, and slightly off to one side.

The information in this section provides the information needed to make the
user aware of a RF exposure, and what to do to assure that this radio operates
within the FCC RF exposure limits of this radio.
2.2 ELECTROMAGNETIC
INTERFERENCE/COMPATIBILITY
During transmissions, M/A-COM radios generate RF energy that can possibly
cause interference with other devices or systems. To avoid such interference,
turn off the radios 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.
3 OPERATING TIPS
Antenna location and condition are important when operating a portable radio.
Operating the radio in low lying areas or terrain, under power lines or bridges,
inside of a vehicle or in a metal framed building can severely reduce the range
of the unit. Mountains can also reduce the range of the unit.
In areas where transmission or reception is poor, some improvement may be
obtained by ensuring the antenna is vertical. Moving a few yards in another
direction or moving to a higher elevation may also improve communications.
