SAFETY INFORMATION

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.
