Getting started
Connecting the adapter to the Hi-Fi equipment
Connect one end of the supplied RCA cable (C) to the AUDIO OUT L (6) and AUDIO OUT R (7) sockets of the
adapter and the other end to the RCA audio input of your Hi-Fi equipment. Alternatively you can use an optical
S/PDIF cable (not supplied) to connect the S/PDIF (8) socket of the adapter to the optical S/PDIF input (if any) of
your Hi-Fi equipment.
Switching the adapter on
Connect the adapter to the supplied power adapter (B) and then connect the power adapter (B) to an easily
accessible power socket. Toggle the power switch (12) located on the back panel of the unit to “ON”. The green and
blue LEDs go on simultaneously. After initialising, the blue LED flashes slowly. The adapter is now in AP mode.
Establishing the Wi-Fi connection
There are 2 ways to connect the adapter (A) to the existing network of your router via Wi-Fi: either by pressing the
WPS button (5) or by downloading the "UNDOK" control app for free from the Apple®App Store or from the
Google®Play Store. In both cases, when establishing the connection for the first time, make sure to place the adapter
(A) as close as possible to the router to achieve an optimum Wi-Fi signal transmission. Then install the adapter (A)
within the Wi-Fi signal range.
Please note that a maximum of 16 devices can be connected to a network.

Establishing the Wi-Fi connection via WPS
If your router features a WPS button, the easiest way to connect the adapter (A) to the network is using this button.
Place the power switch (12) in "ON" position and press the On/Standby button (3) to go to connection mode.
After a brief initialisation period (green and blue LEDs on simultaneously, then one LED lights green) the blue
LED flashes slowly.
Next press the WPS button on your router and confirm the connection by pressing the WPS button (5) on the
adapter (A) front panel.
See the operating instructions for your router.
The adapter (A) establishes a network connection. The blue LED flashes 3 times fast, followed by a short pause.
After the connection has been established, the blue LED goes on.
Now the adapter (A) can play audio signals from the network.
The adapter (A) will save the connection data, so the next time you switch it on you don't need to re-establish
the connection again.
Establishing the Wi-Fi connection via the "UNDOK" app
If you cannot establish the connection using WPS, you can use the "UNDOK" app to connect the adapter to the
network.
Power on the adapter and start the AP mode.
When using it for the first time, the adapter starts the AP mode automatically.
Otherwise hold the RESET button (10) for approx. 5 seconds to restart the adapter.
After a brief initialisation period (green and blue LEDs on simultaneously, then one
LED lights green) the blue LED flashes slowly and the adapter is in AP mode.
Launch the UNDOK App. Select the "Set up new audio system" option to continue.
