temperature fluctuations, wait for it to reach the ambient temperature before switching it on
(about 2 hours).
the device should not be subjected to excessive shocks and vibrations;
the device is not covered. Heat can accumulate when the device is covered, therefore there is a

Electrical devices are not suitable for children. Also persons with reduced physical, sensory or
mental capabilities should only use electrical devices within the limits of their abilities. Do not allow
children or persons with reduced physical, sensory or mental capabilities to use electrical devices
unsupervised unless they are instructed accordingly and supervised by a competent person
responsible for their safety. Children should always be supervised to ensure that they do not play

Only plug the power adapter into a suitable and easily accessible power socket. Do not touch the
power adapter with wet hands as this could cause an electric shock.
To unplug the power adapter from the power socket, always hold its casing and never pull from the
cable. Unplug the power adapter from the mains in the following circumstances:
in any dangerous situation

English - 7
SilverCrest SMRS 35 A1

interfere with the functionality of the pacemaker. The RF signals transmitted can interfere with
hearing aids. If the wireless mode is switched on, do not place the device near flammable gases or
in a potentially explosive area (e.g. a paint shop), as the RF signals transmitted could cause
explosions or fire. The range of the radio frequency signals depends on environmental conditions. If
data is transmitted via a wireless connection, it can also be received by unauthorised parties. Targa

following requirements:
DHCP must be enabled on the network router so the speaker can obtain an IP address
automatically.
UPnP media sharing has to be enabled on the router.
®
App Store and from the Google® Play Store.
See the operating instructions for your router.

Getting started
Switching the speaker on
Connect the speaker to the supplied power adapter (B) and then connect the power adapter (B) to
an easily accessible power socket. Toggle the power switch (8) located on the back panel of the
unit to “ON”. The speaker is now in standby mode. The LEDs are off. There is no Wi-Fi connection.
Establishing the Wi-Fi connection
There are 2 ways to connect the speaker (A) to the existing network of your router via Wi-Fi: either
by pressing the WPS / RESET button (3) 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 speaker (A) as close as possible to the router to
achieve an optimum Wi-Fi signal transmission. Then install the speaker (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 speaker (A) to the network is
using this button.
Place the power switch (8) in "ON" position and briefly press the On/Standby button (1) to
go to connection mode. After a brief initialisation period (yellow 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 /
RESET button (3) on the speaker (A) top.
See the operating instructions for your router.
The speaker (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 speaker (A) can play audio signals from the network.
English - 11
SilverCrest SMRS 35 A1
The speaker (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
speaker to the network.
Power on the speaker and start the AP mode.
When using it for the first time, the speaker starts the AP mode automatically.
Otherwise hold the WPS / RESET button (3) for approx. 5 seconds to restart the
speaker. After a brief initialisation period (yellow and blue LEDs on simultaneously,
then one LED lights green) the blue LED flashes slowly and the speaker is in AP mode.
Launch the UNDOK App. Select the "Set up new audio system" option to continue.
Follow the on-screen instructions to connect the speaker to your Wi-Fi network.
During the connection process you can assign a unique name to the speaker so you can
better identify it on the network.
After setup is finished you can add more existing Wi-Fi speakers to the network, if any.
Spotify Connect
Spotify is a music streaming service that runs on many mobile devices like smartphones or tablet
PCs. Together with one of these devices your speaker SMRS 35 A1 can play this streamed music.
Requirements:
You have to download the Spotify App to your smartphone (iOS, Android) and install it.
