This guide explains the setup of multiple DX340|HD base stations.
INTERFERENCE AVOIDANCE
Multiple base stations can operate on High or Low parts of the frequency band to prevent interference (heard in a headset as
mechanical sounding voices; voices breaking up while talking; or hearing a “Busy” prompt in the headset when a button is pressed).
For example, if you have two base stations, set one on low band and another on high band, according to the steps below.
NOTE: Base stations are shipped in the “A” (default) position. A “c” will only appear on the STATUS display the rst time you are
setting the frequency band, or if you are changing the setting. If you stop at an L, H, Aor Ethat was previously 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 that were registered to that base station.
1. Turn the base station power on.
The status window will display “8” for a few seconds and
then go blank.
2. Simultaneously press and hold the CLEAR/BAND button
and the REGISTER button. The STATUS window will
display an L, H, Aor E(Europe).
L=Low End
H=High End A=All E=Europe
3. Quickly, press the CLEAR/BAND button repeatedly to
cycle through parts of the frequency band to stop at the
desired L, H, Aor Esetting.
Wait until “c” appears on the STATUS display.
