Appendix A: Exposure to Radio Frequency Energy
Warrior handheld remote transmitter units and receivers contain radio transceivers. When active,
a handheld remote sends out radio frequency (RF) energy through its internal antenna. The
Warrior
handheld remote 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 that are
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:
Those 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.
The required separation distances are measured from the actual location of the radiated part of
the antenna. An antenna may be inside the host application, affixed to the enclosure of the host
application, or at the end of an optional extension coaxial cable.
Mobile Applications
Equipment must be located in a location at least 20cm 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 proper equipment
operation training, 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 is on the hand or arm, a 5mm separation between the radiating
part of the antenna and nearby human tissue is required.
Required Training
All installers and operators of host applications that include an SRF310 radio transceiver module
must
be trained to use proper RF safety precautions.
