1. Safety instructions

General

• Please READ this user manual before the first use.

• Please KEEP this user manual.

• Please FOLLOW the specified operating and safety
instructions.

Disclaimer

• beyerdynamic GmbH & Co. KG will not be liable for any
damage to the product or injury to persons caused by
negligent, improper, incorrect or inappropriate
operation of the product.

Troubleshooting / repairs

• Never open the device yourself.

• Refer all service work to authorised professionals only.

Cleaning

• Only clean the device with a dry or slightly damp cloth.
Never use solvents, as these will damage the surface.

Rechargeable battery

• The handheld transmitter is operated with the a
lithium ion battery, which must replaced by trained
service staff only.

• Use only a USB 2.0/3.0 compliant 5V power supply to
charge the battery via the integrated USB
type-C port (power consumption is max. 500 mA).

• High temperatures, paicularly in association with a
high charging atus, result in irreversible damage of
the battery.

• If you are not intending to use the battery for an
extended period or are planning to put it into orage,
it is advisable to lower the battery’s charging level to
around 50% and to ore it at temperatures of maxi­mum 30 °C.

• In order to ensure safe transpo by land, sea and air,
the battery used for the handheld transmitter is teed

6

Unite TH – Handheld Transmitter

according to the UN 38.3 transpo regulation for
lithium-ion batteries.

• Misuse or improper use could damage the battery. In
extreme cases, there is a risk of explosion, heat, fire,
smoke or gas.

• Never expose the battery to excessive heat such as
sunshine, fire or the like.

• Do not expose the battery to mechanical shock.

• Charge the battery before initial use.

• Use the specified chargers for charging the battery.

• Avoid complete draining of the battery. This could
damage the battery and shorten its service life.

• If you do not use the transmitter for several months,
the batteries should be charged at least twice a year
to prevent deterioration in performance due to self­discharge.

• Clean the charging contacts of the transmitter with a
clean dry cloth, if they become dirty.

• Do not short-circuit the battery.

• The charging contacts could cause property damage,
injuries or fire damage if they come into contact with
conductive materials such as jewellery, keys or chains.
This can lead to a closed electric circuit and, therefore,
to the material overheating. To avoid this kind of
unintentional electric circuit, the charging contacts
must be handled with care. This is especially important
if the transmitter is transported in a bag or another
container containing other metallic objects.

Moisture / heat sources

• Keep the battery clean and dry. Never expose the
device to rain or high humidity. Do not install it in the
immediate vicinity of swimming pools, shower
facilities, damp basements or other areas with
unusually high air humidity.

• Never place objects filled with water (e.g. vases or
drinking glasses) on the device. Liquids in the devices
may cause a short circuit.

• Never install or operate the device in the immediate
vicinity of radiators, lighting systems or other heat­ generating devices.

4. General operation

• Important: Before using the handheld transmitter for
the first time, you must charge the built-in battery.
Please use an appropriate Unite charger or the USB
connection.

• Switch on the transmitter by pressing the on-off
button .

• In order to establish an audio connection between a
transmitter and one or more receivers, all devices
must be paired together. See chapter 5.

• All devices are supplied with the group ID 256 and
fixed audio encryption allowing quick and easy initial
use.

• The transmitter will only transmit the audio signal on a
channel with a predefined channel name. If there are
several transmitters in a group, the channel for the
respective transmitter can be selected on the receiver.

• If you require several device groups or an audio trans­mission even more secure against eavesdropping, to
avoid listening by other groups using Unite devices,
follow the steps in chapter 5 to create a new pairing.

4.1 Maintenance

• Protect the handheld transmitter from humidity, knocks and
shock. Avoid dropping the transmitter at all times.

• For cleaning the plastic surface of the handheld transmitter
use a soft cloth moistened with a solvent-free plastic
cleaner.

4.3 Tips and Tricks

• Avoid holding the handheld transmitter at the top or bottom.

You could cover the integrated antennae and therefore
reduce the range. Always hold the handheld transmitter in
the middle.

13

english

Wrong hand position

Correct hand position

• 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 possible. The intelligibility of speech is
significantly increased.
The Noise Gate function suppresses annoying background
noise.

• If the “ALC” function is deactivated, it is advisable to reduce

the gain for loud speakers and to increase the gain for quiet
speakers. In either case, use the on-off and menu button



to access the “Audio” menu and the “Volume” and “Internal
Mic” submenus. 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 be set in the menu, serves as an audio interface for
playing various audio sources as well as for playing back
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 be carried out first. A detailed
description of the procedure can be found in the
comprehensive “Unite” manual on the internet at
www.beyerdynamic.com.

Unite TH – Handheld Transmitter

5. Create / define a new pairing

Transmitters and receivers must be 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 soft­ware 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
be set to the “Pair & Charge” position so that the pairing
information can be 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 be
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
problems with the receivers!
