CAUTION TO USERS
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter. This device is approved with emissions having a source-based time-
averaging duty factor not exceeding 50%.
Vehicle – Antenna Installation:
- Antennas used for this transmitter must not exceed an antenna gain of 3 dBi with a
minimum cable loss of 1dB.
- For rear deck trunk and roof top installations, the antenna must be located at least 91 cm
(36 inches) away from rear-seat passengers and bystanders in order to comply with the
FCC RF exposure requirements.
The following label will be mounted in conspicuous view on the radio.
Failure to observe these restrictions will result in exceeding the FCC RF exposure limits.

SYNCHRONISM BOARD
2.6.1.
INTRODUCTION
This module carries out two very important tasks in the infrastructure:
It provides a synchronism signal:
It provides an NMEA 0183 V2.01 sequence, consisting of date and time.
It also provides a PPS signal (1 pulse per second), retrieved from the GPS as
well. This pulse makes it possible to synchronise different Base Station Sites
in a network.
This feature may optionally be made redundant to yield two equivalent output
signals.
It provides a reference clock signal.
The module additionally yields a 10-MHz clock signal with a 0.1 ppm stability.
There are four variants of the synchronism board, depending on its location and
availability of GPS in the board . Thus, the board is named MSYNC or MSYNC GPS when it
is positioned in the MNI Rack, or BSYNC or BSYNC GPS when it is placed in a BSR75.
