Close the battery compartment by pressing its cover down until both latches snap in place.
NOTE: Simultaneously pressing down on the cover next to both of the latches will assure proper
closing.
If using the DX100 with an external DC power source We recommend that you purchase a
12V DC power cord adapter for a standard vehicle power port, then purchase and attach a
“Switchcraft 760K” DC power plug. Follow the manufacturer’s instructions to connect the
external DC power source to the power connector on top of the DX100. Any power supply used
with the DX100 should be rated at least 12VDC, 500mA.
NOTE: Having a fully charged (or new) battery when operating the DX100 with AC or external DC power can
prevent interruption of communication during a power outage. This allows the base station to seamlessly
switch to battery power.
If only one base station will be used, skip pages 9 – 12 and turn to page 13.
If more than one base station will be used, continue with all instructions on the following pages.

REGISTRATION
STATUS display
Interference Avoidance
Interference (ex: headset 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 DX100 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). Here’s how:
Step 1. Turn on the Base Station power.
The number “8” will appear on the REGISTRATION STATUS display for a
few seconds.
Step 2. After the “8” disappears and the REGISTRATION STATUS
display is blank (primary base) or shows a double bar
(secondary base), press and hold the CLR/BND button. While
you are still holding the CLR/BND button, press and hold the
REG button and wait until a L, H or A appears. Release both
buttons.
Step 3. Press the CLR/BND button to cycle through
parts of the frequency band; L = Low end,
H = High end, A = All, and E = European mode.
Step 4. Wait until “c” appears on the display.
NOTE: Base stations are shipped in the A (default) position.
“c” will only appear on the REGISTRATION 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
REGISTRATION 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.

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.
Primary and Secondary Base Station Settings
One base station must be designated as “primary” and all others must be designated as “secondary”. You can have only
one primary and up to 3 secondary base stations. Secondary base stations are assigned numbers 1, 2, or 3.
Label the base stations as “Primary”, “1”, “2” and “3”.
Start with every base station and Beltpac/Headset power off.
Set DIP Switches
Open each secondary base station and set
DIP switch #4 to the ON position as follows.
Using a T9 torque wrench, remove the
six screws from the front panel of each
secondary base station. Lift the front
panel carefully and set it face down.
Be careful not to pull any wires loose.
Locate the DIP switch on the transceiver circuit board inside the front panel of each secondary base station.
Set DIP switch #4 to the ON position. Leave #s 1 and 3 in the OFF position.
Replace the front panel and screws on the secondary base stations.
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 be properly initialized before
performing any other setups. After initializing each base station, register each Beltpacs/Headsets to that base
according to the procedures on pages 13 - 16.
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 is started. (See Interference Avoidance on page 9.)
Initialize each base station and register all Beltpacs/Headsets as follows:
Primary Base Station
Turn the primary base station power on. Register any Beltpacs/Headsets to be used with the primary base
station (See pages 13 - 16). Turn each Beltpac/Headset off after registering it.
Secondary Base Stations
Step 1. Power-on one secondary base station.
The REGISTRATION STATUS display will show a double bar,
indicating the secondary base station is ready to be initialized.
Step 2. Press the REG button on the primary base station.
The REGISTRATION STATUS display will show a small “o”.
Step 3. To assign a number to a secondary base station and initialize it, press
the REG button on the secondary base. Pressing the button repeatedly
cycles through the numbers 1, 2, and 3. When the desired number
appears, release the button and wait. While the secondary base
initializes, the REGISTRATION STATUS display will continue
showing the selected number. When secondary base station initialization
is finished, the display will show one bar indicating that the secondary
has initialized to the primary.
Step 4. Press the REG button on the primary base station.
The REGISTRATION STATUS display will go blank.
Step 5. Register Beltpacs/Headsets to the secondary (See pages 13 - 16).
Step 6. After registration, turn off the secondary base and all Beltpacs/Headsets
will be registered.
Step 7. Repeat the above steps for each remaining secondary base station. Use a
different number for each. Only the primary base and the secondary base to
be initialized should have power during initialization. All other equipment
should be turned off.
Step 8. After all secondary bases are initialized and Beltpacs/Headsets are registered, power-up all base stations.

Step 9. Press the RESET button on the primary base, and let it recover.
Step 10. Turn on the primary Beltpacs/ Headsets, and let them link.
Step 11. Press the RESET button on each secondary base station (one at a time), and
let it initialize to the primary base (indicated by a single bar).
Step 12. Turn on the Beltpacs/Headsets associated with the secondary base stations. Work with one group at a time
until they have all linked, and then do the next group. At this point all base stations and Beltpacs/Headsets
should be powered-up, linked and ready for use.
Step 13. Now proceed with normal system configuration, setting functions and levels as required.
Step 14. If it becomes necessary to replace a secondary base station, initialize the new secondary with the same
number as the replaced secondary. After initialization, you will have to register any Beltpacs/Headsets to the
new secondary.
Step 15. If it becomes necessary to replace a primary base station, follow the preceding instructions completely.
Before initialization of the secondary base stations, clear the previous secondary initialization as follows.
For each secondary, press the CLR/BND button and the
RESET button simultaneously. Release the RESET button,
but continue pressing the CLR/BND until the clear
code “c” (lower case) appears on the
REGISTRATION STATUS display.
Any Beltpacs/Headsets associated with the old primary
base station will have to be registered to the new primary,
following secondary base station initialization.
All Beltpacs/Headsets associated with secondary base stations also have to be registered again.
Step 16. If the primary base is shut down or 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 REGISTRATION STATUS displays will show
three bars. If the primary is turned back on, it will be necessary to press the
RESET button on all secondary bases to allow them to find and initialize to the
primary again. It’s therefore important to have all base stations connected to the
same AC circuit to prevent this situation when the system is shut down after
hours and powered up again the next day.
NOTE: You cannot register Beltpacs/Headsets to a base that is set to 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. The primary base must remain active, and the secondary base should display one bar.

BELTPAC / WH220 HEADSET SETUP AND REGISTRATION
The first time you operate the DX100 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 Beltpacs/ Headsets when their
power is on. They will also recognize other electronic equipment operating on the same frequencies. If a
Beltpac/Headset is added, replaced or repaired later, the new one must be registered (the previous one will
remain in memory). Since only 15 Beltpacs and/or Headsets can be in memory, whether currently in use or not,
all memory must be cleared to remove any old Beltpac/Headset registrations.
Set Up Beltpacs
Before registering them, 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.

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 have already been registered
can be on or off.
NOTE: If you are setting up multiple base stations, the following steps must be repeated for Beltpacs to be
registered to each base station.
Step 1. Place on your head the headset of the Beltpac to be registered.
Step 2. Press the REG button on the front panel of the base station.
The REGISTRATION STATUS display on
the base station will show a small “o” (for open).
NOTE: If you wait too long before going on
to Step 3, the base station will exit
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.
Step 4. The two power lights at the corners of the Beltpac near the IC and
ISO buttons will begin blinking red. They will then blink green two
or three times and turn off.
Wait! There may be a short delay.

Background
The Clear-Com DX wireless intercom systems utilize a Frequency Hopping Spread Spectrum (FHSS) radio
in order to provide robust communications.
This system operates in the unlicensed 2.4 GHz band. With the proliferation of other devices over the past few
years in the same 2.4 GHz band, instances where these devices and systems can interfere with each other has
greatly increased.
The European Union has introduced new radio standards for equipment operating in this band in an attempt to
reduce interference between equipment from different manufacturers. European Telecommunications Standards
Institute (ETSI) EN 300 328 v.1.8.1 compliant when operated in the E mode.
CLEAR-COM Adaptive Frequency Hopping
In order to reduce interference with other equipment and comply with these new regulations, Clear-Com has
implemented an Adaptive Frequency Hopping (AFH) “E” mode to base stations. The key idea behind AFH is
using only the good frequencies, or channels, unoccupied by other equipment. The system scans for other
signals and avoids these signals during operation. Since the radio environment is constantly changing, there is a
continuous process of scanning for used frequencies and updating the list of good channels.
The Clear-Com system utilizes 46 discrete frequencies, or channels, within the 2.4 GHz spectrum in order to
communicate voice and data. The process of deciding which channels should be used is a 3-stage process. The
process includes scanning for occupied channels, the broadcast of a channel exclusion list and the use of the
exclusion list. The process is completed in three steps coexisting in time.
Below is the process is shown in Time. First, the system performs a channel scan to determine occupied
channels. This list is then broadcast to the communicator. The communicators and base station will use this list
during period three. The process is continuous, and as is illustrated below, the list could be constantly changing.
Depending on the radio environment, a maximum of 46 channels, and a minimum of 15 channels may be used
by the system at any time.

Operation in Severe Environments
During normal operation, the fact that the system is constantly changing the channel list in use is transparent to
the user. It is possible, however, that in an environment with severe interference that the system may experience
a slight degradation. In the AFH mode, the Clear-Com system will use a minimum of 15 channels. If the
environment is very crowded and less than 15 channels are truly available, there could be increased radio
‘packet loss’ due to the high interference. The following symptoms may be observed with AFH systems in a
highly congested radio environment:
This may result in system ‘busy’ indications. Channel lists are updated every few seconds, and in a
severe environment it is possible that these lists get missed by the communicator.
Slight degradation in audio fidelity between the headsets and base station. This would be due to the
same symptom as the ‘busy’ indications. The HD audio processing is tolerant to this condition, which
is why the degradation may only be slight.
Longer times to register. Registration may take longer, since the headset has to acquire the channel list
from the base station. If the base station has excluded a lot of channels, this takes longer as the
communicator does not have the exclusion list and looks for the base on channels it is not using.
Initial sync time increase. For the same reason registration may take longer, the initial headset sync on
power up may take longer.
Required AFH Equipment
In order to utilize AFH, the base station must be set to European mode. The headsets and belt packs must also
be AFH capable. AFH capable headsets and belt packs will have the letters ‘AFH’ labeled on the belt pack and
headsets. AFH communicators will auto detect if the system is in AFH mode and adjust their operation
accordingly.
Non-AFH Equipment
Headsets and belt packs that are not AFH capable must be operated with either a non-AFH base station or an
AFH base station selected to operate in All, High or Low band mode. Headsets and belt packs that are not AFH
capable will not have the letters ‘AFH’.

Interference Mitigation
Certain techniques can be used in an attempt to mitigate interference between different equipment in the 2.4
GHz spectrum. Some of these are:
Physical separation. If possible, equipment operating in the 2.4 GHz spectrum should be operating as
far as physically possible from the HME base station. A Wi-Fi access point or router is a common
piece of equipment that could interfere with the DX100 system, or vice versa. These two pieces of
equipment in particular should not be located close together.
Spectral separation. Most Wi-Fi access points allow the administrator to set the channel and
bandwidth that system operates on. Some systems employ an ‘auto’ mode, in which the Wi-Fi access
point will automatically selected the channel. With Wi-Fi access points, it is sometimes advantageous
to manually select a channel number to keep the Wi-Fi transmission at a fixed location.
NOTE: If the Clear-Com system does not have AFH, then the base station should be set to operate in the region
of the 2.4 GHz band where the Wi-Fi access point is not operating. For example, if the Wi-Fi access point is set
to Wi-Fi channel 1, the base station should be set to operate in the ‘High’ band. If the Wi-Fi access point is set
to channel 11, the base should be set to operate in the ‘Low’.
Spectral efficiency. Wi-Fi systems employ a standard sometimes referred to as 802.11. The number
“11” is simply the number given to the standard by the Institute of Electrical and Electronics Engineers
(the IEEE). Modern Wi-Fi routers will allow operation employing the 802.11n mode. This mode will
allow higher data rates, but it also may consume twice the number of radio channels. If the Wi-Fi
router is set to 802.11n mode, it is best to limit Wi-Fi bandwidth to 20 MHz.
Alternate band selection. While most Wi-Fi systems operate at 2.4 GHz, which is the same band as
the DX100 system. Most allow operation at 5 GHz. If possible, move any Wi-Fi access points and
equipment to 5 GHz. This of course requires all Wi-Fi equipment to be 5 GHz capable, and most older
equipment may only allow 2.4 GHz operation. Selection of 5 GHz may also not be desirable if the WiFi network is for customer access.
25
If you are unable to correct any of the problems described below, contact your dealer for assistance.
Red light on base station does not come on.
Be certain power cords are properly connected to base station, power supply and electrical outlet.
If battery operated, be certain six AA batteries are inserted in the indicated positions in the battery sled, and
the sled is installed in the base station. See pages 7-8.
Beltpac power lights do not turn green and “out of range” is heard in the headset.
Be certain your base station power is on. Turn the Beltpac/Headset and base station power on and off.
You may be too far from the base station. The range varies with each location’s layout.
If you have more than one base station, be sure the Beltpac/Headset is registered to the base station it is
being used with. If you are not sure, re-register it.
When trying to register, it keeps saying registration failed.
Check to be sure that the REGISTRATION STATUS display only goes blank, and does not show a
registration number. Follow the instructions on clearing the registrations as found on page 13 or 15, and
repeat the registration procedure.
Others cannot hear me when I talk.
Be certain you are pressing the IC or ISO button on the Beltpac/Headset, or the microphone gain adjust is
turned up to the required level. If you are using a Beltpac, be certain the headset is securely connected to the
Beltpac unit. See pages 18-21.
SECTION 5. TROUBLESHOOTING
In the event of an electrical power outage —
such as from a lightning storm or power generator failure, if you experience problems with your HME
equipment after the electricity comes on again, unplug the AC power supplies from their electrical outlets,
remove any batteries and wait 15 seconds, then plug them back in.
2400MHz cordless telephone interference —
If there is a 2400MHz cordless telephone nearby, interference may occur. However, because the DX100 is a
frequency-hopping system, this problem is unlikely. If it does occur, changing frequencies on the telephone
may alleviate the problem. If not, move the phone as far as practical from the base station, or use another type
phone.
