Introduction
DC-ConneX™ Translate Tour creates the most inclusive group experience across multiple
languages and social distances. Connect 2 Leaders to a single group or 1 Leader and 2
Translators to 3 different groups. This solution is ideal for translators or multilingual tours (up to 3
languages).
Translate Tour units are ultra-compact and lightweight with advanced digital technology. The
simple design provides easy operation with high-quality performance and functionality. A
rechargeable lithium-ion battery offers up to 9 operating hours on leader units and up to 14
operating hours on guest units.
Leader and guest units are designed to work in specific frequency ranges of 900MHz (US/CA
only), 863MHz (EU only), and 2.4GHz (Global). The US/CA & EU frequencies are dedicated audio
communications bands that provide for far less chance of interference compared with 2.4GHz
frequencies which share that frequency with Bluetooth®, Wi-Fi® and other devices that can
interfere with each other.

Operations
The Translate Tour solution can support two channels of communication simultaneously. This
feature can be used to support numerous multi-speaker and multi-group applications. The
illustration below shows 3 typical use cases. Case 1 is the simplest where 1 or 2 leaders use L1
units to speak simultaneously to a single group. Case 2 and Case 3 use L1 and / or L2 units to
support multiple groups with multiple speakers. Refer to the Detail Set-up Instructions for Case
1, Case 2, and Case 3 section in this User’s Manual for settings specific to L1, L2, and G units for
proper setting selections.
Unpack and Prepare Your Device for Set-up

Set-up

STEP 1: Plug the Headset or Earphone into the units
DCX-L200 L1: Plug the microphone into the unit where the microphone icon appears.
DCX-L200 L2: Plug the headset into the unit where the headset icon appears.
DCX-G100 G: Plug the earphone into the unit where the earphone icon appears
(there are two, use either or both for two people sharing one unit).
STEP 2: Turn On
Long press the power button and adjust the volume to the level you desire.
L1 – Leader 1 and Guest use as in Case 1
The single group Translate Tour system is now ready to use with up to two leaders and unlimited
Guests! Each L1 Unit requires a unique ID number if two L1 units are used.
L2 – Leader 2
L2 Units are not used in the Case 1 application. For use of L2 in Case 2 and Case 3 applications
see the section entitled “Detail Set-up Instructions for Case 1, Case 2, and Case 3 Applications”.

11 | P a g e
Recommendations for use:
- Fully charge each unit prior to use.
- The earphones have an inline microphone and volume
control. Set the earphone volume at the highest level
(move slide forward to the + symbol). Adjust volume to a
comfortable level on Leader 2 (L2) or Guest (G) units.
- The factory ships all units with Channel (CH) number set
at “00”. Check the Channel (CH) number on all Leader
and Guest units to confirm all units have the appropriate
CH number set.
- The units must be powered off manually. There is no
automatic shut off.
- Do not run the unit battery to empty as this degrades the
life of the battery.
Mode & Mute On/Off

DCX-L200 L1 (Leader 1)
L1 is a talk-only unit that uses a single channel to transmit. In
normal operation, the L1 unit is un-muted. This is indicated by
the talk icon on the display.
- Long press the Mode button to enable mute. The
Talk icon will disappear from the display indicating the
unit is muted.
- The number displayed indicates the Channel that
the unit is transmitting on.
DCX-L200 L2 (Leader 2 or Translator for example)
L2 is a talk and listen unit that uses a different channel for talk and listen. L2 does not have a
mute on/off function but rather uses a press and hold of the Mode button to change the
channel selection from receive to transmit when talking.
- When the Mode button is pressed the transmit channel will be displayed along with
the Talk and icons, and sidetone will be heard.
- The number displayed indicates the Channel that the unit is transmitting on.
DCX-G200 (Guest)
The Translate G is a listen-only unit that uses a single channel to receive audio. Therefore, there
is no mute on/off function. The Mode button has no effect on operations.
- The number displayed indicates the Channel that the unit is receiving on.
Sidetone
Sidetone is typically a feature
found in higher end audio
communication systems and
serves two key purposes:
1. Provides real time
feedback to the
speaker on how well
they are being heard
by their audience.
2. Restores natural
sounding conversation
when noise
attenuating earphones
or headsets are used.
The audio from the
microphone is fed back into the
headset or earphone of the
speaker giving clear feedback
on quality of the audio. The
speaker will know real time if
the audio being transmitted is
poor or non-existent.
If the speaker uses a noise
attenuating headset or
earphones sidetone provides
the additional benefit of
restoring natural sounding
conversation improving the
whole tour experience.

Audio Alerts

-Low battery:
oSingle high pitch tone followed quickly by 2 lower frequency tones which recurs
every 2 minutes until the battery is recharged or has insufficient charge remaining.
oThe battery indicator will be at zero when the tone is heard. The battery should be
immediately replaced or recharged.
-Out of range or Lost Connection (Guest & L2 units):
oConnection to the Leader is established: 2 beeps will be heard. The signal bar
icon appears on the display.
oConnection to the Leader is lost: 3 beeps will be heard in quick succession. This
alert will repeat until the connection is fully lost and then stops. The signal bar icon
also disappears from the display.
oConnection can be lost or established by being out of range of the leader, the L2

Detail Set-up Instructions for Case 1, Case 2, and Case 3 Applications

Review Settings and Functions section of this User Manual prior to actual set-up of the units.
The Translate Tour system supports simultaneous two channel operation that enables multi-speaker
and multi-group applications. It is important to understand what each type of unit can do.
- L1 units transmit audio on a single channel and do not receive audio.
- L2 units are able to receive audio on one channel and transmit on a different channel.
- Guest units receive audio on a single channel and do not transmit audio.
In setting up the Units, it is important to pair the different units correctly via the channel selection on
each unit. This requires that you understand that the meaning of the Master icon for the L2 units
in normal mode and settings mode is different.
- L1: The Master icon indicates that the L1 unit is the audio transmitter for the
indicated.
- L2: In normal operation, the Master icon indicates the audio transmit Channel for
L2 (same as L1). However in Settings mode, the Master icon is associated with the audio
receive Channel . The Participant icon is associated with the transmit Channel .
- Guest: There is no Master or Participant icon. The Channel for audio receive appears
on the display.

13 | P a g e
Note: Two speakers may concurrently speak to a single group using L1 units (Case 1) on a single
Channel . In this case each L1 unit must have a unique ID. The ID may be changed under
Settings (L1 units only).

Line-in on DCX-L200 (L1), L210 (L2)

The Translate Tour provides the ability to provide background sound to the Tour Guide operation.
This can be music or any audio file. Commonly this is an MP3 or similar audio file played from a
phone or dedicated music player.
-Connect the optional auxiliary line-in cable (DCX-LC-01) between the Leader Line-in input
and an external audio source as shown. Use the external audio source to set the
desired volume.
Note: The auxiliary line-in cable (DCX-LC-01) uses the CTIA TRRS standard wiring
which is the most common standard in the market. To work correctly the external
device’s audio output should conform to this standard.
Charging

The Leader and Guest units may be charged via a USB-C or via charging stations or cases via
direct connect.
-Charging is indicated by a solid Red color LED on the lower right side of the display area.
The LED turns off when charging is complete, unless the unit remains on (possible with
USB charging).
-A rapid blinking Red LED indicates a charging failure. This is most often caused by a poor
connection from the battery to the unit (remove cover and check) or the USB charging
source not suppling sufficient power to the unit (try another charger).
-Devices charged via the USB cable will continue to operate during the charging operation.
Charging will not happen as quickly as when the unit is powered down.
-Devices charged via direct connect through the case or charging stand will not operate,
turning off automatically when the device is connected to the charging case or stand if not
already turned off.

Trouble Shooting Guide
Problem
Cause
Solution
Power does not turn on.
Empty or low battery.
Charge or replace the battery.
Turns off after turning on.
Low battery. Display will show “Lb”
when trying to power on, but then
shutoff “OF”.
Charge or replace the battery.
Audio not heard.
Earphone or Headset not
completely connected.
Check connections are complete and
in the correct position. Connector
may have to be pushed in very firmly
to fully seat it in the unit.
Out of range of leader.
Guests will not hear anything if the
leader unit is turned off or not close
enough.
The Leader unit is not operating at
the same frequency as the Guest
or other Leader units.
Check the front display area to be
sure the units are operating on the
same frequency (2.4Ghz, 902MHz or
863MHz).
CH assigned to leader and guest is
not the same.
Set all users to the same group
number.
Obstacle between leader and
guest.
Move to another place to avoid
obstacles.
More than 1 leader in the vicinity is
in the same group.
Move away from 2nd leader or
change group assignment.
CH and or ID settings are not valid.
Confirm programming referencing
guidelines herein for Case 1, 2, or 3
as desired. Note that 863MHz units
should have at least 3 steps
difference between the L2 receive
and transmit channels selected.
Unknown cause.
Occasionally, the network connecting
Leaders and Guests will cease to
function properly. This can be
resolved by turning off all units.
Then, power on the Leader 1 (L1)
unit first. Follow this by turning on all
the Leader 2 (L2) units. Last, turn on
the Guest units.
Leader 2 units no transmit
audio (no Sidetone) but
still receiving audio.
Not pressing and holding the PTT
(Mode) button.
Be sure to fully press AND hold the
PTT button.
Audio is distorted.
Microphone gain is set too high.
Check settings on transmitting unit.
Change to lowest setting.
Connectors are not fully seated.

it in the unit.
Headset or earphone is defective.
Try a different headset or earphone.

20 | P a g e
Problem
Cause
Solution
863MHz units have a very narrow
frequency band in which to operate
because of the EU/UK frequency
allocations. In some situations the
transmit and receive channels can
interfere with each other.
If using 863MHz units be sure the L2
unit receive and transmit channels
are set at least 3 steps.
Auxiliary audio does not
broadcast.
(Leader unit only)
Aux cable connection is incorrect.
Check connections. Connector may
have to be pushed in very firmly to
fully seat it in the unit.
Volume on the audio device is
muted or turned down.
Unmute or increase volume on audio
device.
Distance from Leader to
Guest is shorter than
expected.
There are obstacles between the
Leader & Guest Unit.
Move to an area where objects are
not interfering.
There is interference from other
devices operating in the same
frequency. This is unlikely with 902
or 862MHz systems. 2.4GHz
systems operate alongside
Bluetooth, Wi-Fi and other
systems.
Move to a location with fewer
phones, PCs or other active devices.
Switch to a 902MHz or 863MHz
system if you are in the US.
Unit will not shut down.
Software fault.
Remove the battery or
simultaneously press the down/up
and mode buttons.
Red charging LED
remains on for more than
the 6 hours of typical
charge time.
The battery will typically fully
charge in about 6 hours but the red
LED may remain on for a few
hours after the battery is fully
charged due to differences in
chargers and some small amount
of trickle charge that’s going on.
Battery status can be checked on the
display to confirm the charge state.
If the battery takes much longer than
6 hours to charge this is a sign the
battery may be aging and should be
replaced.
Red LED remains on
when charging.
The Red LED may remain on while
charging via the USB port and the
Unit is left on. This is because to
stay on the Unit will continue to
draw power which requires a USB
power draw.
This is normal operation.
If this happens when the unit is
powered off, this is a sign the battery
may be aging and should be
replaced.
