4.3 Tips and Tric s
• Avoid holding the handheld transmitter at the top or ottom.
You could cover the integrated antennae and therefore
reduce the range. Always hold the handheld transmitter in
the middle.
• At the factory the ALC (Automatic Level Control) and Noise
Gate functions are activated.
With the ALC function the handheld transmitter
automatically adjusts the gain to ensure the signal volume is
as consistent as possi le. The intelligi ility of speech is
significantly increased.
The Noise Gate function suppresses annoying ackground
noise.
• If the “ALC” function is deactivated, it is advisa le to reduce
the gain for loud speakers and to increase the gain for quiet
speakers. In either case, use the on-off and menu utton 
to access the “Audio” menu and the “Volume” and “Internal
Mic” su menus. Adjust the volume or microphone gain
accordingly.
• For an optimal speech transmission,
ensure a consistent distance to the
mouth. Avoid holding the microphone
closer or farther to the mouth. Also,
avoid turning your head while
speaking.

• The Bluetooth® function of the handheld transmitter, which
can e set in the menu, serves as an audio interface for
playing various audio sources as well as for playing ack
audio signals. In order to connect the Unite TH handheld
transmitter with another device (e.g. headphone,
smartphone or computer) via Bluetooth®, pairing with the
connecting device must e carried out first. A detailed
description of the procedure can e found in the
comprehensive “Unite” manual on the internet at
www. eyerdynamic.com.
5. Create / define a new pairing
Transmitters and receivers must e paired so that they
can communicate with each other. For a successful
pairing the channel name, group ID and audio encryption
key are required. The required audio encryption key is
generated in the charger or via the Unite Manager soft-
ware and during the pairing process it is first stored on the
charger and then it is transferred to the transmitter and
receiver in the charger. In this context, please also note
the position of the switch on the charger. The switch must
e set to the “Pair & Charge” position so that the pairing
information can e transmitted from the charger to the
transmitters and receivers.
There are three different ways to pair the Unite transmitters
with receivers:
1. Via an individual charger (refer to the following
description or system manual online).
2. Using the Unite Manager Software on a PC (refer to
the Unite Manager Software manual or system
manual online).
3. Via dynamic channel search (refer to system manual
online, chapter “Special functions”.
Use with group ID 256
By default, the transmitters and receivers are supplied
with the group ID 256.
A factory-set audio encryption key, which cannot e
changed, is used for the factory-set group ID 256. The
audio encryption key ensures additional security against
unauthorised listening. You can use the group ID 256 for
a system without pairing.
Receivers with the group ID 256 can find and connect to
all transmitters with the group ID 256. This is done via the
dynamic channel search on the receiver.
Attention: When using several transmitters (e.g. Unite AP4
and several Unite TP) with the group ID 256 at the same
time, make sure that the individual channel names differ
from each other! Otherwise this can cause connection
pro lems with the receivers!

english
Unite TH – Handheld Transmitter 15
Use with individual group ID
If several receivers are to e divided into different
groups, for each group an individual group ID can
e assigned. A separate audio encryption key is
generated for an individual group ID in order to
ensure additional security against unauthorised
listening. This audio encryption key is generated
during the pairing process, stored in the charger and
transmitted from the charger to the transmitter and
receiver, along with the channel name and group ID.
Since the audio encryption key is not transmitted via
radio, it cannot e read out. This gives the system
maximum security against unauthorised listening.
The receivers can only connect to a transmitter with
which they have een paired. If the group ID is
su sequently set manually on the receiver, no
connection can e esta lished ecause the audio
encryption key does not match. Please note that the
transmitter to which the receivers are to e
connected must e defined as the master.
5.1 Encryption
The audio data is always encrypted with an AES-256
code to ensure a secure transmission. The required ey
will be generated within the charging unit itself and
transmitted to the transmitters and receivers during the
pairing process.
As the key is not transmitted via radio, the system is even
etter protected against eavesdropping.
Should the receiver receive a different encrypted audio
signal for which no key has een saved, the received
audio signal will e muted. The receiver display will also
alternate etween showing the relevant channel name
and the “KEY!” error message.
The encryption of the audio signal is shown schema-
tically in the following diagram.

Note: Only group ID 256 uses a factory-defined key that
cannot e changed. You can use this group ID for a
system without pairing.

5.2 Set group ID
The group ID identifies devices that can e placed in a
virtual group. For example, all devices of a uilding, a tour
group or a conference room.
The factory-preset group ID is 256. To set a group ID
etween 1 and 255, follow the steps elow:
• Press and hold the menu utton for 2 seconds to
activate the main menu.
• Use the multifunction utton to select “System” from
the menu.
• Press the menu utton  to open the required su menu.
• Use the multifunction utton  to select the “Group ID”
su menu.
• Press the menu utton to set an group ID.
• Use the multifunction utton to select the desired
group ID.
• Press the menu utton  to confirm the selected group ID.
Make sure to select the same group ID for all devices of a
desired group. Only devices that have the same group ID
can communicate with each other. Transmitters with other
group IDs are hidden. See the following diagram.

• Press the menu utton  to open the required su menu.
• Use the multifunction utton  to select the “Channel
Name” su menu.
• Press the menu utton  to set the channel name.
• Use the multifunction utton  to scroll through the
characters. When the desired character appears,
confirm using the menu utton . You can input max.
five characters.
• As soon as you select the configured transmitter on
the receiver, the defined name will e displayed on the
receiver’s display.
• The following diagram shows an example of two
transmitters with different channel names, and a
receiver that can find and switch etween oth

In order to perform a simple pairing, proceed as
descri ed in the following:
1. Set the desired group ID on the transmitter you want
to use for pairing. See chapter 5.2 for reference.
2. Insert only one transmitter into the charging slot of
the charger. If multiple transmitters are inserted into
the charging slots of the charger, the pairing will not
start and the status indicator on the charger will
display an error (see ta le). Alternatively, you can
connect the transmitter to the USB port on the
charger via a USB ca le.
3. Insert one or more receivers into the charging slots of
the charger to e paired with the transmitter. You
can also connect another receiver to the charger
using the USB port. Remove all receivers that should
not e paired. If there is no receiver in the charging
slots, the pairing information is stored in the charger.
This is used for later pairing without connecting the
transmitter to the charger.
4. In order to transfer the pairing information from the
transmitter to the receivers in the slots and to the
charger itself for future pairing, press and hold the
“Pair/Reset” utton on the charger for more than
2 seconds. The status indicator will flash yellow for
several seconds if the pairing is successful. The
status indicator will then remain yellow ecause the
pairing information is now also stored in the charger.
5. If you want to pair other receivers, remove the trans-
mitter and all receivers from the charger, set the
switch to “Pair & Charge” and insert the unpaired
receivers into the charger. The pairing information will

e stored immediately in the unpaired receivers. The
status indicator on the receiver will flash yellow ra-
pidly while this happens.
6. Set the switch  ack to “Charge only” when the
pairing is finished, so that the charger can only e
used for recharging.
7. Switch on the transmitter and one receiver to check
that they have oth een paired successfully.
After a few seconds, the status indicator on the
receiver should light up green and the display should
show the channel name of the transmitter.
8. If you want to clear the stored pairing information,
hold down the “Copy/Reset utton  for more than
five seconds. The status indicator will then remain
permanently green.
