Appendix A: Exposure to Radio Frequency Energy
Warrior
transmitters and machine units contain radio transceivers. When active, a transmitter
sends out radio frequency (RF) energy through its internal antenna. Warrior transmitters and
receivers comply with limits set by the United States Federal Communications Commission
(FCC) for operating distance from human tissue
.
Appendix B: RF Exposure Considerations
The radio module may be used in a variety of host applications falling into two general
categories:
1.
Mobile
applications: Any operating locations where the transmitting equipment is
not
on
a human body. In mobile applications, the host application is typically fixed to mobile
equipment, with either an internal or external antenna.
2.
Portable
applications: Any operating locations where the transmitting equipment
is
located on the hand, arm, or other part of the human body. In portable applications, the
equipment is either held in the hands of an operator or affixed to either a belt or harness
on the torso.
Equipment containing the radio module was evaluated for RF exposure hazards by two
approaches:
1. Maximum Permissible Exposure (MPE) for mobile applications.
2. Specific Absorption Rate (SAR) for portable applications.
Required separation distances are measured from the actual location of the radiating part of the
antenna. An antenna may be inside the host application, affixed to the host application
enclosure, or at the end of an optional extension coaxial cable.
Mobile Applications
Equipment must be located at least 20cm away from areas likely to be occupied by an unaware
person.
Transmitter Applications
All operators of transmitter equipment with any type of antenna require proper equipment
operation training, and such training must include RF exposure safety instructions. They are
then considered to be “aware” persons once training is completed.
If the portable operating position is on the hand or arm, a 5mm separation is required between
the radiating part of the antenna and nearby human tissue.
Required Training
All installers and operators of host applications that include an SRF310 FT module
must
be
trained to use proper RF safety precautions as presented in this Appendix.
