2. Important Information for the User
2.1 Transmitter Warm-up Period
The Base transmitter uses a precision oven-controlled crystal oscillator (OCXO). The
OCXO warm-up period is one minute minimum after application of input power
before any transmission should commence.

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 although the Base station is expected to be
sited, installed and maintained only by professionals in a controlled exposure
environment, the RF Energy Exposure Guide lists the larger lateral safe distances for
an uncontrolled environment. Obeying these limits will protect both railroad
employees and the general public.

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

This radio is intended for use by railroad employees who have full knowledge of
their exposure and can exercise control over their exposure to meet FCC and IC
limits. This radio device is not intended for use by consumers or the general
population. Base station antennas must be positioned on towers or non-residential
buildings that are generally unoccupied except while servicing the equipment
therein.
