Appendix A: Exposure to Radio Frequency Energy
Warrior system transmitter and receiver units contain radio transceivers. When active,
transmitters/receivers send out radio frequency (RF) energy through an internal (or external)
antenna. The Warrior Locomotive CB transmitter complies with limits set by the FCC for
operating distance from human tissue
.
Appendix B: RF Exposure Considerations
Radio modules 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 in a location at least 20 cm away from areas likely to be occupied by
an unaware person.
Handheld Applications
All operators of the handheld equipment with any type of antenna require training in the proper
operation of the equipment and such training must include RF exposure safety instructions.
Once training is completed, they are considered to be aware persons.
If the portable operating pose in on the hand or arm, a 5-mm 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 section.
