FCC EXPOSURE LIMITS
This mobile radio transceiver was tested by the manufacturer
with an appropriate antenna in order to verify compliance with
Maximum Permissible Exposure (MPE) limits set under Section
2.1091 of the FCC Rules and Regulations. The guidelines used in
the evaluation are derived from Figure 1 (B) titled “Limits For
General Population/Uncontrolled Exposure” which is from FCC
report OET bulletin #65.
