This feature prevents ISO communication from being broadcast from one COMMUNICATOR

to other
Communicators. Local headset ISO will still be broadcast, and the local headset will still receive ISO
communication. To enable this feature, set JP4 to ON.

Power Detect Bypass

In the event the DX210 base station is connected to a 2-W line which does not contain power (such as
when multiple base stations are daisy chained), JP1 (IC1) and/or JP2 (IC2) need to be set to ON to
enable 2-W interface for the respective channel(s) to come on.

WARNING! If no termination is present on the line, enabling this feature will cause feedback in
the headsets.

2-Wire Channel Termination

If termination of the base station is necessary (such as when multiple base stations are daisy chained), set
the JP5 (IC1) and/or JP6 (IC2) jumpers to the ON position on one base station, when connecting multiple
base station together via 2-wire connection. Only one base station should be terminated per channel.

NOTE: If using split-band operation, select the appropriate band prior to base station registration. If a
different frequency band needs to be selected to avoid interference, the primary base station must be
set to this frequency band before base station registration is started.

Register each base station and all Belt Packs and/or All-In-One Headsets as follows:

 On one of the base stations, ensure that the primary/secondary switch is set to primary. On the

others, ensure that it is set to secondary.
NOTE: In split band operation, there can be one primary and up to three secondary base stations in
either band.

systems can be limited to one portion of the band. If so, the DX210 can be set to the opposite half of the

2.4 GHz to 2.48 GHz band. To avoid this type of interference, select the upper or lower part of the
frequency range.

 Turn on the base station power. An “8” will appear on the STATUS display for a few seconds.
 After the “8” disappears and the STATUS display is blank (primary base station) or shows a double

bar (secondary base station), press and hold the CLR/BND button and then, while you are still
holding the CLR/BND button, press and hold the REG button and wait until a L, H or A appears, and
then release both buttons.

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

 Press the CLR/BND button to cycle through parts of the

frequency band, (L = Low end, H = High end, and A = All)
and stop on the desired setting.

 Wait until “c” appears on the display.

NOTE: “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.

NOTE: If you change a base station’s frequency band setting, you will have to re-register all

all COMMUNICATOR s to be used with each base station as instructed in section 2.3.2,

unicators that were registered to that base station. Comm

Spectrum Friendly

All DX Series wireless intercom systems now feature Spectrum Friendly™ technology for interference-free
operation in the increasingly crowded 2.4GHz frequency band. This new technology enables broadcast
and theatrical production crews to avoid emerging frequency conflicts by designating the 2.4GHz operating
frequency range: low-, high-, or full-band. While generally not a problem when separated, multiple
applications and multiple users of the same applications in close proximity can result in additional risk for
trouble-free operation. The new technology further ensures that products do not add interference to the
spectrum for other essential wireless services in the vicinity, such as DMX-controlled lighting.

Avoiding Wi-Fi Interference

To avoid interference with Wi-Fi systems, it is recommended to set the Wi-Fi system to something other
than channel 6 or 7.

Your DX210 should be set to the high or low band opposite any Wi-Fi frequency range in use.
