2.2 Limiting RF Exposure
Please refer to the RF Energy Exposure Guide packed with each radio for
specific information regarding safe distances that must be maintained
between personnel and energized transmitting antennas.
specific information regarding safe distances that must be maintained
between personnel and energized transmitting antennas.
The information in the RF Energy Exposure Guide is determined from FCC and
Industry Canada rules that when followed, limit human exposure to radio frequency
energy to acceptable levels. Note that the RF Energy Exposure Guide calculates the
larger lateral safe distances for an uncontrolled environment. Obeying these limits
will protect both railroad employees and the general public.

This transmitter is intended to be operated with a mobile antenna in an
Occupational/Controlled Exposure environment per FCC OET 65 or Controlled Use
Environment per IC RSS-102. To protect the safety of employees and the general
public, application of the Maximum Permitted Exposure (MPE) limit for devices in
the presence of the general public in the 100-300 MHz range, 0.2 mW/cm

The licensee, installer, maintainer and locomotive operators must take into account
all transmitting antennas on the locomotive with regard to potential RF exposure. In
general, it is recommended that all locomotive transmitters with cab top antennas
be disabled before accessing the cab top area.
