2 Important Notes
The unit corresponds to all relevant directives of the EU and is therefore marked with €.
- The unit is suitable for indoor use only. Protect it against humidity and heat (admissible ambient temperature range 0–40°C).
- For cleaning only use a dry, soft cloth; never use chemicals or water.
● Always insert two (rechargeable) batteries of the same type.
- If the unit is not used for a longer time, remove the (rechargeable) batteries as a precaution to prevent damage to the unit caused by battery leakage.
- No guarantee claims for the unit and no liability for any resulting personal damage or material damage will be accepted if the unit is used for other purposes than originally intended, if it is not correctly operated or not repaired in an expert way.

If the unit is to be put out of operation definitively, take it to a local recycling plant for a disposal which is not harmful to the environment. Never put exhausted batteries / defective rechargeable batteries in the household waste; always take them to a special waste disposal (e.g. collection container at your retailer).
3 Applications
In combination with a receiver or several receivers of the type ATS-16R, the transmitter ATS-16T creates a mobile wireless transmission system for speech and music. This system is ideally suited for any application where the signal of one audio source is transmitted to several people, e.g. for guided tours or multilingual lectures. For wireless transmission, 16 channels in the frequency range of 863–865MHz are available. (For simultaneous use of several channels see the note in chapter 7.)
3.1 Conformity and Approval
Herewith, MONACOR INTERNATIONAL declare that the transmitter ATS-16T is in ac cordance with the basic requirements and the other relevant regulations of the directive 1999/5/EC. The declaration of conformity is available on request from MONACOR INTERNATIONAL.
The system is licence-free and generally approved for operation in EU and EFTA countries.
4 Power Supply
The transmitter and the receiver can be supplied with power via batteries, rechargeable batteries or a 5V power supply unit.
4.1 (Rechargeable) Batteries
Each unit is supplied with two 1.2V rechargeable NiMH batteries. For fast and convenient charging of these batteries, the following items are available as accessories:
– the charging station ATS-16PS (for charging the batteries of up to 2 trans- mitters/receivers at the same time)
– the transport and charging case ATS-36C (for charging the batteries of up to 36 transmitters/receivers at the same time)
Instead of the rechargeable batteries, two 1.5V AA batteries may be used.
To insert the (rechargeable) batteries:
1) Slightly press the marked area on the battery compartment cover (8) while simultaneously pulling the cover downwards.
2) Insert the (rechargeable) batteries with their positive and negative connections as indicated in the compartment.
3) Replace the cover and lock it into place.
4.2 Power supply unit
Connect a power supply unit with an output voltage of 5V and a permanent rating of 150mA to the jack DC IN 5V (11). For connection a low-voltage plug of the dimensions 3.5/1.3 mm (outside/inside diameter) is required. The positive pole must be at the inside contact of the plug.
Attention: To prevent damage to the batteries or to the transmitter/receiver, always remove the (rechargeable) batteries from the battery compartment before connecting a power supply unit.
5 Selecting the Signal Source
The transmitter can be operated with a microphone, however, a unit with line output level may also be connected.
a) Microphone operation:
– Either use the internal microphone (5)
- or connect an external microphone, the supplied electret tie clip microphone or the neck microphone ECM-16N (available as an accessory) to the jack MIC. (6). When the jack is connected, the internal microphone will be switched off. Place the windshield on the microphone and attach the microphone to your body: attach the tie clip microphone to your clothes (e.g. lapel) via its clip or put the neck microphone around your neck.
b) Operation with an audio unit:
Connect the output of the audio unit (e.g. cassette recorder, CD player) via a 3.5mm plug to the jack AUX IN (10). When connecting the jack, both the internal microphone and any external microphone connected to the jack MIC. (6) will be switched off.
6 Selecting the Sound Reproduction
The receiver offers different ways to reproduce the sound.
a) Via the internal speaker:
The sound of the speaker can either be radiated freely or be directly transmitted to your ear via the acoustic tube earphone ET-16 available as an accessory. Place the acoustic tube into the opening (5) provided on the receiver and insert the yellow earpiece into your ear in such a way that a tight fit is ensured.
b) Via the supplied earphone:
Connect the earphone to the jack EAR. (6) and attach it to your ear. When con necting the jack EAR., the internal speak er will be switched off.
c) Via an amplifier system:
Connect the amplifier via a 3.5mm plug to the stereo jack AUX OUT (10).
Note: When connecting the jack AUX OUT, the internal speaker is still switched on. To switch it off, connect a 3.5mm plug to the jack EAR. (6).
7 Operation
1) With the adjusting wheel (3) on the transmitter, select the channel for transmission from the 16 channels (0 to F): Turn the wheel in such a way that the arrow below it will point to the desired channel (in fig. 1, channel 0 is adjusted as an example).
Set the adjusting wheel (3) on the receiver to the same channel.
2) Attach the units to your clothes, e.g. your belt, via their clips (7).
For attaching the units to your body, the following items are available as additional accessories:
- ATS-16BAG, protective bag, to be attached to your belt via a loop
- ATS-16CORD, neck cord (for attaching it to the unit see fig. 3)

Mechanical assembly diagram showing a suspended component with rope and clamp, enclosed in a circle (no text or symbols)3) To switch on the units, turn the control (4) clockwise from the position OFF:
On the transmitter, the LED TX (1) shows green to indicate transmission of a radio signal.
On the receiver, the red LED PL (2) briefly lights up first. Then the LED RX (1) shows
green to indicate reception of a radio signal from the transmitter. (If it fails to light up, check if the transmitter and receiver have been adjusted to the same channel.) When the LED TX or RX (1) changes to red, the (rechargeable) batteries are almost exhausted. When the LED TX or RX is extinguished and the red LED PL (2) lights up instead, the (rechargeable) batteries are completely exhausted.
4) With the control (4), adjust the volume for the audio signal transmitted on the transmitter and the reproduction volume on the receiver.
5) In case of poor reception or interference please check
a) if the reception can be improved by using a different transmission channel.
b) if the transmitter and the receiver are too far apart.
c) if the reception is disturbed by objects in the transmission path.
6) To switch off the units, set the control (4) to the left stop (OFF):
On the transmitter, the LED PL lights up for a few seconds before it is complete ly extinguished.
On the receiver, the LED PL flashes briefly.
Note concerning multichannel operation
(Simultaneous operation of several ATS-16 sys tems)
It is possible to simultaneously operate 5 to maximally 8 transmission systems transmitting on different channels. The number of channels to be used in parallel depends on the distance between the individual transmission systems, on any local RF interference sources and other local conditions. When operating several systems, assign the channels in ascending order (e.g. for 8 systems, use the channels 0–7) and keep the systems as far apart as possible.
