ABT00101
Bluetooth 5.0 Audio Transmitter & Receiver
Instruction manual
Thank you for choosing our Bluetooth audio adapter. With
this device, you can wirelessly transmit the sound of an au-
dio source in transmitterr mode (TX) and play it back with a
Bluetooth headset or speaker. In Receiver mode (RX), you
can receive a Bluetooth audio signal form a smartphone
or similiar and play it back on an audio amplifier, wired
headset, or the like. Power can be supplied from the built-in
battery or an USB-A port.

3. Pairing/coupling mode
In order to connect 2 Bluetooth devices with each other,
you must pair them for the first time and activate pairing
manually. The next time you switch on the device, the
pairing will then take place automatically. The connection
information is stored until the mode (TX/RX) is changed.
For resetting the connection memory, please change the
mode within 3 seconds after switching off (e.g. switch
off - slide switch from TX to RX) Then switch on for a short
time, switch off and set the desired mode.
3.1 Using the Transmitter Mode TX)
When the unit is switched off, slide the switch to TX. Then
press and hold the MFB for 2 seconds to turn on the
ABT00101. Briefly press the pairing button to enter pairing
mode. The LED will then flash evenly and rapidly in blue.
Switch the Bluetooth function of your device (Bluetooth
headphones, speaker or receiver, etc.) to pairing mode.
On most devices, an LED will flash alternately red/blue or
blue only to signal pairing mode. After about 5–30 sec-
onds, the ABT00101 will be connected to your device. The
LED then flashes slowly in blue. Connect the ABT00101 to
an audio source, e.g. TV, radio, game console, using a 3.5
mm audio cable or Toslink cable.
Note: The blue LED may blink differently to indicate the
audio codec in use, see appendix. The ABT00101 always
tries to establish the connection in the highest quality
codec aptX-HD first, then aptX Low Latency and so on.
When the audio cable is plugged in, the system automat-
ically switches to the respective operating mode (optical
digital connection or analogue).
3.2 Multipoint with 2 headphones
Initially couple the first device as previously described in
3.1. Then briefly press the pairing button. The blue LED
flashes quickly again and indicates the pairing mode. Now
switch a second Bluetooth device (e.g. headphones) to
pairing mode as well. After 5–30 seconds it is paired. The
LED now lights up constantly green. You can now listen to
music with 2 headphones at the same time.
Note: If it does not work the first time, please switch off
the ABT00101 and carry out steps 3.1 / 3.2 again. A few
Bluetooth devices do not support Multipoint.
3.3 Using the Receiver Mode (RX)
With the unit turned off, slide the switch to RX. Then press
and hold the MFB for 2 seconds to turn on the ABT00101.
Briefly press the pairing button to enter pairing mode.
The LED will then flash evenly and rapidly in red and blue.
Switch the Bluetooth function of your device (mobile
phone, notebook, PC, etc.) to pairing mode. For Android
smartphones, you can find the function under the
Bluetooth settings „Pair new device“. On your iOS device,
select Settings > Bluetooth and enable Bluetooth. After
the FeinTech-ABT00101 is found, tap the device name
to pair. Then connect your audio device (HiFi amplifier,
car radio, etc.) via the analogue 3.5 mm connection or
digitally via Toslink.
Note: The blue LED can blink differently to indicate the
audio codec used, see appendix.
If a password is requested, enter „0000“, „1234“, „8888“
or „1111“.
3.4 Multipoint with 2 telephones
Initially couple the first device as previously described in
3.3. Then briefly press the pairing button. The LED flashes
quickly again in blue & red and indicates the pairing
mode. Now activate Bluetooh on a second smartphone
and search for new devices. Once the FeinTech-ABT00101
is detected, tap this name. There are now 2 sources
paired and the LED is constantly green.
Note: Only one device can play music at a time. Music
from the second device will not be played until the first
device is paused. Here, too, the best possible playback is
attempted using aptX-HD. The LED is lit green, there is no
Codec signalling by the LED.
4. charging
If the LED flashes red, the battery must be charged. To do
this, connect the device to a USB socket on a computer or
USB charger. Full charging will take up to 2 hours. During
charging, the LED will be permanently red. The red LED
goes out when fully charged.
Note: A Bluetooth connection is also possible during
charging.
5. Reset
To reset the ABT00101, press and hold the power button
while plugging in the charger cable.

*If you prefer aptX Low Latency instead of high quality audio in aptX
HD, you can deactivate aptX HD on the ABT00101 as follows: Press
and hold the multifunction button for approx. 8 seconds until the
LED lights up 1 x green. aptX HD is then deactivated and aptX Low
Latency is prioritised as a codec. To reactivate aptX HD, press and
hold the multifunction button for 8 seconds until the LED lights up
2 x green.
