Appendix A: Exposure to Radio Frequency Energy
Warrior MCB transmitter and receiver units contain radio transceivers. When active, an MCB
transmitter sends out radio frequency (RF) energy through its internal antenna. The Warrior
MCB transmitter complies 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 that fall into two general
categories:
1.
Mobile
applications: Any operating locations
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: Applications where the transmitting equipment
is
located
on the hand, arm, or other part of the human body. In portable applications, the
equipment is typically held in the hand 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.
Handheld Applications
All operators of MCB equipment with any type of antenna require proper equipment operation
training, and such training must include RF exposure safety instructions. Once training is
completed, they are considered
“aware persons.”
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 radio frequency
transceiver (RT) module
must
be trained to use proper RF safety precautions as presented in
this appendix.
