that base station will hear a tone in their headset, repeating every 8 seconds and both headset select lights will blink

Spectrum Friendly™ Interference Avoidance

Multiple base stations can operate on high or low parts of the frequency band to prevent interference, which may be heard in a headset as popping sounds

For example, if you have 4 base stations, set 2 on low band and 2 on high band, as follows

NOTE: If you have more than one base station, the one you set up for interference

avoidance will be considered the “primary” base station

All other “secondary” base stations will automatically set themselves to the same frequency band as the primary base station when they are initialized

Turn the base station power on

The STATUS window will show “8” for a few seconds

After the “8” disappears, the

STATUS window will be blank

Press and hold the CLEAR/BAND button and, while you are still holding the CLEAR/BAND button, press and hold the REGISTER button

The STATUS window will show L, H or A

Press the CLEAR/BAND button repeatedly to cycle through parts of the

frequency band ― L = Low end, H = High end and A = All

Stop at the desired setting and wait until “c” appears on the STATUS display

NOTE: Base stations are shipped in the “A” (default) position

“c” will only appear on the STATUS display if you are setting the frequency band the first time, or you are changing the setting

If you stop at L, H or A that was already set, an “8” will appear for a few seconds and the STATUS display will become blank

If you change a base station’s existing frequency band setting, you will have to re-register all beltpacs and/or all-in-one headsets that were registered to that base station

Primary/Secondary Base Station Setting

On the right side of the base stations, leave the BASE switch in the PRI position for the primary base station

Move the BASE switch to the SEC position on each secondary base station, and then press the base station POWER switch twice to turn the power off and back on again

Multiple Base Stations

Up to 20 coaches can communicate using the DX300, 5 per base station, by interconnecting up to 4 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

With the primary base station powered on first, turn on the secondary base station

The STATUS window will show a double bar

Status window with double bar

Press the REGISTER button on the primary base station

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)

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 them with the number of the base station they are registered to, for later identification

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

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

The display will also go blank after timing out

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