1 Applications
In combination with one or multiple receivers ATS-
20R, the transmitter ATS-20T provides a mobile
digital wireless system for transmitting spoken
language, e. g. for guided tours, lectures in different
languages or wireless command transmission. For
wireless transmission, 16 channels are available in
the frequency range 863 – 865 MHz; up to 4 of these
channels may be used at the same time without
mutual interference. The transmission range de-
pends on local conditions and may reach 100 m as
a maximum.
2 Important Notes
The units correspond to all relevant directives of the
EU and are therefore marked with
•
The units are suitable for indoor use only. Protect
them against dripping water and splash water,
high air humidity and heat (admissible ambient
temperature: 0 – 40 °C).
•
For cleaning only use a dry, soft cloth; never use
water or chemicals.
•
No guarantee claims for the units and no liability
for any resulting personal damage or material
damage will be accepted if the units are used for
other purposes than originally intended, if they
are not correctly connected or operated, or if they
are not repaired in an expert way.
2.1 Conformity and approval
Herewith, MONACOR INTERNATIONAL declare that
the voice transmission system (ATS-20R and ATS-
20T) is in accordance with the directive 2014 / 53 / EU.
The EU declarations of conformity are available on
the Internet:
www.monacor.com
The units are generally approved for operation in
EU and EFTA countries; they are licence-free and
require no registration.
3 Setting into Operation
3.1 Recharging the battery
For mobile operation, the units are equipped with
a rechargeable lithium battery. With a fully charged
battery, the operating time of the re ceiver will be
approximately 20 hours and the operating time of
the transmitter approximately 16 hours.
It is recommended to recharge the battery be-
fore longer use or when the symbol
play (3) starts flashing. To recharge the battery, the
transport bags ATS-12CB and ATS-35CB are ideally
suited; these bags are equipped with a charging
section. The units also offer a micro USB port (6).
This port can be used to connect a power supply unit
with micro USB plug or to connect the USB port of a
computer by means of a suitable USB cable.
As soon as the charging process starts, the
transmitter / receiver is switched off, but the charging
is indicated, the
process can be checked via the battery status indica-
tion . The charging time is approximately 6 hours.
3.2 Connecting the microphone or an
audio unit and connecting the earphone

the clip to attach the microphone to your clothes
(e. g. tie, lapel).
When using the transmitter for wireless trans-
mission of line audio signals, connect an audio
unit (CD/ MP3 player, radio etc.) to the jack

connect an audio unit. The transmitter will auto-
matically switch the input from microphone level
to line level.
2) Connect the earphone provided to the jack
of the receiver (black housing) and attach it to
your ear.
4 Operation
1) First switch on the receiver only: Keep the button
(4) pressed until the display (3) is switched on.
As long as no signal is received, the display
will keep flashing. If no signal is received for 20
minutes, the receiver will be switched off auto-
.
matically to save the battery.
2) Set the receiver to a free transmission channel:
Keep the two buttons + and − (5) pressed for
2 seconds: The symbol
disappear and only the letters CH and the symbol
will keep flashing. Use the button + or − to set
the channel. To confirm the setting, press the but-
ton
or wait for 5 seconds. The symbol
reappear and all indications will start flashing.
The display must keep flashing. If it stops
flashing, interference or signals from other trans-

ation definitively, take them to a local

on the dis-
on the display will
mitters are received. In this case, use a different
channel.
3) If multiple ATS-20 systems are used at the same
time for transmitting different kinds of informa-
tion or different languages, set a different trans-
mission channel for each separate system. You
will be able to make four voice transmissions at
the same time if you use the following channels:
1 – 4 or 5 – 8 or 9 – 12 or 13 – 16
4) Switch on the transmitter and set it to the trans-
mission channel of the receiver. Once a signal
is received, the display of the receiver will stop
flashing.
Note: The minimum distance between the trans-
mitter and the receiver must be 20 cm; otherwise,
the receiver will be muted and its display will
keep flashing.
Hint: To set multiple receivers to the same chan-
nel at the same time, keep the buttons , + and
− on the transmitter and on all receivers pressed
until the units are switched off. Then switch on
the units again: All units have been set to chan-
nel 00. If you now set the transmitter to the
desired channel, all receivers will also be set to
the same channel.
After that it will also be possible to change the
channel on the transmitter during transmission
(e. g. in case of interference); all receivers that
have been switched on will follow automatically.
5) As long as the symbol
play, the buttons + and − of the receiver can be
used to adjust the volume for the earphone.
Caution! Never adjust a very high volume. Per-
manent high volumes may damage your hearing!
6) When a microphone is connected to the trans-
mitter, use the buttons + and − to adjust the
microphone sensitivity (in four levels from
to
). When an audio unit is connected,
one segment behind the symbol starts flashing:
The input is set to line level.
If the transmitter fails to switch automatically to
microphone level or line level:
To switch to line level, keep the button − pressed
for 5 seconds until a segment starts flashing next
to the symbol .
To switch to microphone level, keep the button +
pressed for 5 seconds until the display indicates
