For SD1, maintain an RF safety distance of
1.80 meters for a 7 dBd (9.15 dBi) antenna.
Use of higher gain antennas means
increasing the distance accordingly.
For SD2, maintain an RF safety distance of
1.50 meters for a 7 dBd (9.15 dBi) antenna.
Use of higher gain antennas means
increasing the distance accordingly.
Consult factory prior to operation.
