The DX200 provides private, secure communication. Each base station can register up to fifteen BP200
Beltpacs and/or WH220 All-in-one Wireless Headsets. Any combination of Beltpacs and/or WH220 Headsets
can be registered. Four of the fifteen can transmit simultaneously. However, by connecting two or more base
stations together, these numbers can be increased. For example, two base stations can support thirty Beltpacs/
Headsets, of which eight can transmit simultaneously. Beltpacs or Headsets may be used either in the push-to-
talk or hands-free mode. The base station operator can stop all Beltpacs/Headsets from transmitting.
The DX200 can be used with RTS and Clear-Com cabled intercom systems. On the intercom channel, 2-wire
and 4-wire cabled intercoms may be operated simultaneously. Also, using the AUX In and AUX Out
connections, a second 4-wire intercom channel may be used.
A local headset can be used with the DX200. Using a local headset, the base station operator can talk to crew
members on the cabled intercom channel, Beltpacs/Headsets only, or all channels.
The BS200 Base Station can be operated using standard DC electricity or a vehicle electrical system for mobile
operation. A power supply and cable are included with the base station.

Interference Avoidance
Headset interference, sometimes heard popping sounds, may occur whenever other equipment such as WI-FI
systems, wireless DMX systems or other HME Base Stations use the same frequency band. If these systems
can be limited to one portion of the band, then the DX200 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 part of the frequency range on one Base Station
(or more), and the lower part of the frequency range on the other(s) as follows:
Step 1. Turn on the Base Station power. An “8”will appear on the STATUS display for a few seconds.
Step 2. After the “8”disappears and the STATUS display is blank (primary base) or if it displays a double bar
(secondary base), press and hold the CLEAR/BAND button. Then, while you are still holding the
CLEAR/BAND button, press and hold the REGISTER button and wait for a L, Hor Ato appear. Release
both buttons.
NOTE: Base stations are shipped in the A(default) position.
Step 3. Press the CLR/BND button to cycle through parts of the
frequency band; L= Low end, H= High end and A= All.
Step 4. Wait until “c”appears on the display.
Step 5. Initialize eachBase Station and register all Beltpacs/Headsets to be used with eachBase Station as
instructed on pages 11 –14.
NOTE: “c”will only appear on the STATUS display if you are setting the frequency band the first time or
if you are changing the setting. If you stop at L, Hor Athat was already set, an “8”will appear for
a few seconds and the STATUS display will turn 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 registered to that base station.
Multiple Base Stations
This mode of operation can be used to expand the number of users communicating through multiple HME Base
Stations operating in the same portion of the 2.4 GHz to 2.48 GHz frequency band. Two or more base stations
can be “daisy-chained” together with 2-wire connector cables (#27 and #29) on the rear panel of each base station
(following Clear-Com /RTS standards).
NOTE: The base station does not provide or require 2-wire line power.
The cable connectors must RTS Mode Clear-Com Mode
be 3-pin XLR type with the Pin 1 = Common Pin 1 = Common
following pin connections: Pin 2 = Channel 1 Pin 2 = N/C
Pin 3 = Channel 2 Pin 3 = Audio
If you are “daisy-chaining” multiple base stations:
Step 1. Press TERM button in (TERM ON) to terminate
the last base station in the daisy chain.
Be sure this is done to only one base station.
Step 2. For each base station, follow all the steps under
Equipment Connections on page 7.
Step 3. Follow the procedures on pages 9 and 10 to set
each base station as primary or secondary, select
frequency bands and initialize each base station.

9
Primary and Secondary Base Station Settings
One base station must be designated as “primary” while others are designated as “secondary”. You can have
one primary and up to three secondary base stations. Secondary base stations are assigned numbers 1, 2, or 3
during initialization to differentiate them in frequency offset.
Label the base stations as Primary, 1, 2and 3.
Start with all base stations and Beltpac/Headsets powered off.
Configure each secondary base station as follows:
1. Remove the six screws from the top and three screws from each side of the top cover, and then remove and
set aside the cover.
2. Locate the DIP switch on the transceiver circuit board inside the base station. Set DIP switch #4 to the ON
position. Leave #s 1 and 3 in the OFF position.
3. Replace the cover and screws on the base station.
4. The primary base station DIP switch #4 should be in the OFF position.
Base Station Initialization
For multiple HME base stations to operate without interference, they must all be properly initialized before
performing other setups. After initializing each base station, register each Beltpacs/Headsets to be used with
that base according to the procedures on pages 11 - 14.
NOTE: Base stations must be set up for split-band operation prior to initialization. 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 initialization begins. (See Interference Avoidance on page 8.)
Initialize each base station and register all Beltpacs/Headsets as follows:
1. Power on the primary base station. Register any Beltpacs/Headsets to be used with the primary base station
(See pages 11 - 14). Turn off each Beltpac/Headset after it has been registered.
2. Power on one secondary base station. The STATUS display will show a double bar, indicating the
secondary base is ready to be initialized.

4. To assign a number and initialize it to a secondary base station, press the REGISTER button on the secondary
base. Pressing the button repeatedly cycles through numbers 1, 2, and 3. When the desired number appears,
stop pressing and wait. During initialization, the STATUS display will continue showing the secondary
number. When initialization is completed, the display will show one bar, indicating that the secondary has
initialized to the primary.
5. Press the REGISTER button on the primary. The STATUS display will go blank.
6. Register Beltpacs/Headsets to the secondary (See pages 11 - 14). After registration, turn off the secondary
base and all Beltpacs/Headsets.
7. Repeat these steps for each remaining secondary base. Use a different number for each. Only the active
primary base and secondary base to be used should be powered on during initialization. All other equipment
should be turned off.
8. After all secondary bases are initialized and Beltpacs/Headsets are registered, power up all bases. Press reset
on the primary base and let it recover. Turn on the primary Beltpacs/Headsets, and let them link. Press the
reset on each secondary base (one at a time), and let it initialize to the primary (indicated by a single bar).
Turn on the Beltpacs/Headsets associated with the secondary bases one group at a time until they have all
linked. Follow with the next group. At this point, all bases and Beltpacs/Headsets should be powered up,
linked and ready for use.
9. Proceed with normal system configuration, setting functions and levels as required.
10. If it becomes necessary to replace a secondary base, use the procedure above to initialize the new secondary.
After initialization you will have to register any Beltpacs/Headsets associated with the old secondary to the
new secondary.
11. If it becomes necessary to replace a primary base, follow the above procedure completely. Before
initialization of the secondary bases, clear the previous secondary initialization as follows. For each
secondary, press the CLEAR/BAND button and the RESET button simultaneously. Continue holding the
CLEAR/BAND button after releasing the RESET button until the clear code “c” (lower case) appears on the
STATUS display. Any Beltpacs/Headsets associated with the old primary will have to be registered to the
new primary after secondary base initialization. All Beltpacs/Headsets associated with secondary base
stations also have to be registered again.
12. If the primary base is shut down or if the primary base is
powered off for more than 30 seconds, all secondary bases will
drop their Beltpac/Headset connections and begin searching for
the primary. If the primary is not found in 30 seconds, the
secondary will automatically revert to primary-mode operation
and reconnect the Beltpacs/ Headsets. At this point, the
secondary STATUS displays will show three bars. Once the
primary powered on, it will be necessary to press RESET on all
secondary bases to allow them to find and initialize to the
primary again. This makes it important that all bases be
connected to the same AC circuit to prevent this situation in the
event that the system is shut down at the end of a day and
powered up the next day.
NOTE: You cannot register Beltpacs/Headsets to a base that is set in primary mode, and then switch the
base mode to secondary for initialization. Once in secondary mode, the base cannot recognize the
Beltpacs/Headsets registered during primary operation. For secondary bases, the Beltpacs/Headsets
must always be registered after secondary base initialization, with the primary base remaining active
and the secondary base displaying one bar.

BELTPAC / WH220 HEADSET SETUP AND REGISTRATION
The first time you operate the DX200 system, you must register each Beltpac and/or WH220 Headset for use
with a specific base station. The base station will then recognize all registered and powered on
Beltpacs/Headsets, and it will differentiate between them and other electronic equipment operating on the same
frequencies. If a Beltpac/Headset is added, replaced or repaired later, the new one must be registered and the
old one remains in memory. A maximum of 15 Beltpacs and/or Headsets can be registered to a single base
station at one time. If the maximum number of 15 is exceeded, you must clear all current registrations and re-
register all active Beltpacs/Headsets.
NOTE: The following two pages are for Beltpac setup and registration. WH220 Headset setup and
registration instructions are on pages 13 and 14.
Set Up Beltpacs
Before registration, set up all Beltpacs as follows.
Step 1. Insert a fully charged battery in the
Beltpac with the metal contacts on
the end of the battery inserted first.
Press itin until it snaps.
Step 2. Place the Beltpac in the pouch.
Step 3. Plug the headset cable connector into the Beltpac.
Register Beltpacs
Beltpacs must be within 6 feet (1.83 meters) of the base station during registration. Before you begin, be certain
the base station power is on and each Beltpac to register is turned off. Beltpacs that are already registered can
be turned on or off.
NOTE: If you are setting up multiple, daisy-chained base stations, the following steps must be repeated for
Beltpacs registration to each base station.
Step 1. Put the headset, of the Beltpac being registered, on your head.
Step 2. Press the REGISTER button on the front panel of the
base station (#17 on base station front panel illustration).
The STATUS display (#3on base station front
panel illustration) will show a small “o” for open.
NOTE: If you wait too long before going on to Step 3,
the base station will go out of the registration
mode and you will have to repeat Step 2.
Step 3. Press and hold the ISO button on the Beltpac while you press and
release the PWR (power) button to turn the unit on, then release the
ISO button. This will cause the Beltpac to enter the registration mode.
The two power lights at the corners of the Beltpac near the IC
and ISO buttons will begin blinking red, then they will blink green
two or three times and turn off.
Wait! There may be a short delay.

If registration is successfully completed:
A voice message in the headset will say “Power on, Beltpac #, Version #, Begin registration, Registration
complete, …”
After a delay of up to 15 seconds, the STATUS display will show the ID number assigned to this Beltpac for
about 10 seconds.
NOTE: ID numbers are assigned sequentially as 0 thru 9, A, b, C, d and E.
The power light on the Beltpac, next to the IC button, will remain on steady green.
Repeat Steps 1 to 3 on page 11 for each Beltpac to be registered.
If registration failed:
A voice message in the headset will say “Power on, Beltpac #, Version #, Begin registration, …” Both
power lights on the Beltpac will be blinking red, and there may be a delay of up to 90 seconds before you
hear “Registration failed” and the STATUS display goes blank.
Press RESET (#16) on the base station. To press RESET, insert a small paper clip or similar object into
the RESET hole at the lower-left corner of the base station front panel. When the STATUS display (#3)
goes blank, press the REGISTER button (#17) and register the Beltpac again. If registration fails again,
call your dealer for assistance.
If you try to register more than 15 Beltpacs and/or Headsets to a base station:
An F(for registration “Full”) will appear on the STATUS display (#3) on the base station, and you
will hear “Registration failed” in the Headset.
Clear all current registrations by pressing the CLEAR/BAND button (#2) and RESET (#16)
simultaneously. To press RESET, insert a small paper clip or similar object into the RESET hole at the
lower-left corner of the base station front panel. Continue holding the CLEAR/BAND button after you
release RESET, until the clear code “c” (lower case) appears on the STATUS display.
Register all active Beltpacs, one at a time. Previously registered Headsets must also be re-registered.
