FCC EXPOSURE LIMITS
This mobile radio transceiver was tested by the manufacturer with
an appropriate antenna in order to verify compliance with Maximum Per-
missible Exposure (MPE) limits set under Section 2.1091 of the FCC
Rules and Regulations. The guidelines used in the evaluation are derived
from Table 1 (B) titled “Limits For General Population/Uncontrolled
Exposure” which is from FCC report OET bulletin #65.
Table 2 lists the antenna whips and bases recommended for use in
each frequency range. Each model of this radio was tested with the appro-
priate antenna listed. The antenna was mounted in the center of the roof
