Up to 20 coaches can communicate using the DX300 (ve per base station) by interconnecting up to four base stations as

described below. With multiple base stations, one will be considered the main or primary base station, and all others will

be considered secondary base stations.

Initialize Multiple Base Stations

Multiple base stations must be “initialized” according to the following instructions,

so their frequencies will not cause self-interference. After initializing each base

station, register each beltpac and/or all-in-one headset that will be used with that

base station.

1 With the primary base station powered on rst, turn on the secondary base

station. The STATUS window will display a double bar.

2 Press the REGISTER button on the primary base station. The STATUS window will show a small “o”.

3 Press the REGISTER button on the secondary base station to assign it a number (1, 2 or 3).

Wait until the base is initialized (approximately 10 seconds).

4 When initialization is complete, the STATUS window will show one bar.

5 Press the REGISTER button on the primary base station to clear the STATUS window.

The display will also go blank after timing out.

6 Repeat steps 1 – 5 to initialize up to three secondary base stations.

CAUTION: If more than two base stations will be used, each secondary base station must be

assigned a different number (1, 2 or 3), or interference will occur

RECOMMENDED: If only two base stations will be used, set the secondary base station to #2

HINT! Mark each base station with its assigned number, and then, when registering beltpacs

and/or all-in-one headsets, mark

Status window

with double
