The rst time you operate the DX410 system, you must register each Communicator (Belt Pack and/or All-In-One
Headset) for use with a specic base station. The base station will then recognize all registered Communicators when

their power is on and will differentiate between them and other electronic equipment operating on the same frequencies.
If a Communicator is added or replaced later, the new one must be registered and the old one remains in memory. A
maximum of 15 Communicators can be registered to a single base station at one time.

Set Up COMMUNICATOR®s

Before registering them, set up all Communicators as follows:

The Belt Pack

h Insert a fully charged battery in each Belt Pack with the metal contacts inserted rst. Slide it in until it snaps.

NOTE: The battery will not slide in if inserted incorrectly. Excessive force should not be necessary.

h The A, B, A & B, or ISO indicator light will be lit for

the selection you made.

h A and B communication will be heard by wireless

users on the respective channel, as well as users

wired into 2-W and 4-W connections.

h ISO is heard in both wireless channels, and AUX OUT if activated.

NOTE: When the ISO button is pressed, ISO RELAY is activated.

h The TALK button (red) is used for communication from the local headset to the selected channel. For open

communication, press and release the TALK button quickly to “latch on.” To “latch off,” press and release the
button again quickly.

For momentary communication, press and hold the TALK button for more than one second. In this mode, the
selected channel will remain open only as long as you are pressing the TALK button. The TALK light indicates

the TALK mode is active via the local headset.

h Use the VOLUME control to adjust the output to the local headset ear piece.

h Use the MIC LEVEL control to adjust the audio level from the local headset microphone.

COMMUNICATOR® OPERATION

Belt Pack control buttons have a snap action. They will activate when pressed rmly. Use your ngertips (not your
ngernails) to press the Belt Pack buttons. All-In-One Headset buttons are touch sensitive.

Power On/Off

h Power On – Press and release the Power button (PWR). A voice prompt in the ear piece will say “Battery

Level”, and the red power lights near the corners of the A and B buttons will turn on. After a short time, one

light will go off and the other will change to green, indicating the Belt Pack is ready for use. The STATUS

indicator on the base station will momentarily indicate the ID of the Belt Pack. The green power light will be on
steady whenever the Belt Pack is ready, but not transmitting.

NOTE: While the Belt Pack is transmitting, the green power light will be ashing.

h Power Off – Press and hold the PWR button for approximately two seconds. A voice message in the ear

piece will say “power off”, and the green power light will turn off.

ISO (Isolate) and A, B (Intercom)

Use the ISO button to talk to other wireless Communicator users and the base station operator. Pressing ISO on the Belt
Pack will also send audio to AUX OUT if the AUXILIARY OUT light on the front of the base station is on. Use the A and B
buttons to communicate via the wired intercom channels and the base station operator. When the ISO button is pressed,
ISO RELAY is activated.

Operating Modes

h Push-To-Talk ONLY Mode Operation – In PTT operation, audio is transmitted only while you are pressing

and holding the A, B or ISO button. When you release the button, transmission stops.

h Hands-free Mode Operation – Quickly press and release the A, B or ISO button to “latch” the transmitter on.

Talk and listen, as in a normal telephone conversation. Quickly press and release the same button again to
“unlatch,” and end the conversation. The base station operator can unlatch all Communicators by pressing the

UNLATCH button on the base station.

NOTE: In the hands-free mode, if you are latched in A, B or ISO, quickly pressing/releasing either of the other

buttons will latch on that button.

Also in the hands-free mode, if you are latched in A or B and then press and hold the ISO button, it will function as PTT.
When you release the ISO button, the Communicator will revert to the latched A or B.

Refer to Communicator indicator light functions, Appendix A (pg. 30).

Volume Up/Down

h Volume Up Adjustment – Each time you press and release the volume-up ▲ button, a beep will be heard in

the ear piece as the volume increases one step. If you press and hold the ▲ button, repeating beeps will be
heard as the volume steps up to maximum. When maximum volume is reached, “maximum” will be heard in
the ear piece, and it will be repeated until you release the ▲ button.

h Volume Down Adjustment – Each time you press and release the volume-down ▼ button, a beep will be

heard in the ear piece as the volume decreases one step. If you press and hold the ▼ button, repeating
beeps will be heard as the volume steps down to minimum. When minimum volume is reached, rapidly

repeating beeps will be heard.

21

Adjusting Microphone Gain

Some users talk louder/softer than others. To allow for this, microphone gain adjustment is available.

h To increase microphone gain – While holding down the B button, press the volume-up ▲ button as many

times as necessary to reach the desired level. The microphone gain increase can be monitored through side
tone, or preferably by someone else using a Communicator or at the base station.

h To decrease microphone gain – While holding down the B button, press the volume-down ▼ button as

many times as necessary to reach the desired level. The microphone gain decrease can be monitored through
side tone, or preferably by someone else using a Communicator or at the base station.

NOTE: The mic gain setting will be indicated, in number format, by a voice prompt (typically, HS14 = 5, HS15
= 3, HS16 = 3). You will hear “Maximum” if you attempt to go higher than maximum mic gain. You will hear

repeating beeps if you attempt to go lower than minimum mic gain. Microphone gain will be saved in memory

and does not require readjustment each time the power is turned on. The Default setting is 3.

EU BASE STATION ADAPTIVE FREQUENCY HOPPING

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.

To further complicate matters, 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. This European

Telecommunications Standards Institute (ETSI) harmonized European standard is known as EN 300 238 v1.8.1.

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) mode for the new DX EU 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.

For instructions describing the process of setting the base to AFH or another scanning mode, see Appendix D:

Interference Avoidance Through Spectrum Friendly, pg. 33.

Available settings include:

High (H) - Scans the Higher frequencies.

Low (L) - Scans the Lower frequencies.

All (A) - All frequencies are scanned.

AFH (E) - (European Mode) Advanced Frequency Hopping searches for the best frequency.

23

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 AHF 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:

h 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.

h Slight degradation in audio delity 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.

h 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.

h 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:

h 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 DX410 system, or vice versa. These two pieces of equipment in particular should
not be located close together.

h 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 xed 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’.

24

h Spectral efciency. 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.

h Alternate band selection. While most Wi-Fi systems operate at 2.4 GHz, which is the same band as the

DX410 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 Wi-Fi network is for customer

access.

TROUBLESHOOTING

Problem THINGS TO CHECK

The Red light on base station power switch does not
come on.

The Belt Pack power lights do not turn green and “out
of range” is heard in the headset.

When trying to register, you keep hearing
“registration failed”.

Others cannot hear me when I talk.

People on the 4-wire intercom cannot hear me, or I
cannot hear them.

Be sure the power cords are properly connected to base
station, power supply and electrical outlet.

Be sure your base station power is on. Turn the Belt Pack
and base station power on and off. You may be too far
from the base station. The range varies with each loca­tion’s layout.

Refer to “If registration failed” in section 2.3.2, page 8,
and repeat the registration procedure. If “F ” shows up on

the STATUS display, it indicates that an attempt has been

made to register more than 15 Belt Packs. Follow the
related instructions in section 2.3.2, page 9.

Be sure the headset is securely connected to the Belt
Pack or base station, and that you are pressing the A, B

or ISO button on the Belt Pack, or the TALK button on the
base station. Be sure the appropriate A, B or ISO setting
is selected in the HEADSET section of the base station

front panel.

Be sure the cables are securely connected and the 4-wire
intercom is on. If using a local headset, be sure the de-

sired IC setting is selected in the HEADSET section of the

base station front panel. If using a Belt Pack or All-In-One
Headset, press the desired IC button.

People on the RTS
me, or I cannot hear them.

The 2-wire intercom is on, and there is a loud squeal

whenever I try to talk.

Settings are not retained when the base station power
is turned off and then back on.

2-W LEDs remain red. No 2-wire power detected.

Echo on 2-W line.

®

/Clear-Com® systems cannot hear

Be sure the cables are securely connected and the 2-wire
intercom is on. If using the local headset, be sure the de-

sired IC setting is selected in the HEADSET section of the

base station front panel. If using a Belt Pack or All-In-One
Headset, press the desired IC button.

This can occur if two or more base stations are dai­sy-chained without terminating the appropriate channel.

The termination is set by putting JP5 (A) and/or JP6 (B)

in the ON position. This should be done in only one base
station. Refer to Appendix C, page 32, for jumper (JP)
locations.

The internal battery may be low. Contact your dealer.

Plug into 2-W power supply. If the lack of powered 2-W

system is intentional (such as when using a Clear-Com
MT1, or when daisy-chaining multiple base stations), open

the base station cover and set JP1 (A) and/or JP2 (B) to

the ON position. If daisy-chaining, do not forget to also

terminate one of the base stations by setting JP5 (A) and/
or JP6 (B) to ON. Refer to Appendix C, page 32, for jump­er (JP) locations.

Be sure no wired Belt Packs have open mics and that the
line is terminated, and rerun Auto Null.

APPENDIX D: INTERFERENCE AVOIDANCE THROUGH SPECTRUM
FRIENDLY

Interference, which may be heard in a headset as popping sounds, may occur whenever other equipment such as Wi-Fi
systems or wireless DMX systems use the same frequency band. Some systems can be limited to one portion of the band. If

so, the DX410 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.

CLR/BND button STATUS display

1. Power up the base station. An “8” will appear on the

STATUS display for a few seconds.

Once 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.

While you are still holding the CLR/BND button, press
and hold the REG button and wait until a L, H, A or
E appears. Release both buttons. Base stations are
shipped in the A (default) position.

NOTE: The EU version of the base station is shipped
in AFH mode E.

REG button

2. Press the CLR/BND button to cycle through parts of the
frequency band, (L = Low end, H = High end, A = All and
E = AFH), and stop on the desired setting.

33

4. Wait until “c” appears on the display.

NOTE: A “c” will only appear on the STATUS display if

you are setting the frequency band the rst 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.

5. Register all COMMUNICATOR®s to be used with each

base station as instructed on page 15.

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

Small “o” indicates Primary base

station is open for registration

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 conicts by designating the 2.4GHz operating frequency range: low-band, high-band 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 DX410 should be set to the high or low band opposite any Wi-Fi frequency range in use.

DX410 Low Band = 2.4000-2.4400 GHz DX410 High Band = 2.4433-2.4830 GHz
