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
with the product. Small parts can represent choking hazards. Keep the packaging away
from children and persons with disabilities.
There is a risk of suffocation.
DANGER! Power adapter
Please only use the supplied power adapter (manufacturer: Ktec / model number:
KSAS0451800250HE) to power the speaker.
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

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
GmbH is not liable for any interference caused to RF or TV signals through unauthorised
modification to this device. Furthermore, Targa accepts no liability for replacing any cables or
devices that have not been specifically approved by Targa GmbH. The user is solely responsible

Installation recommendations and notes about the EQ settings
A carefully chosen location of the speakers is important for obtaining a good sound. Furniture,
curtains and other objects already influence the sound slightly.
You should always try to install the speakers at the height of the listener's head.

SilverCrest SMRS 35 A1
12 - English
In order to minimise any undesired sound reflections, a minimum clearance of 0.8 m behind and
aside of the speakers should be kept. You can check for any sound reflections by moving the
speaker closer and closer to a corner of the room. The bass component will raise the closer the
speaker is placed to the corner.
Negative sound reflection can also occur on the surface (shelve, chest of drawers, etc.) on which
the speaker is placed. There is already a difference in sound when placing the speaker on the front
edge of the furniture or in the centre of it.
Upon delivery, the sound is set for the installation conditions described above.
If you cannot find any location that meets the above requirements, you can still set the speaker
sound in order to optimise it for the given environment.
To do so, select the sound setting that best describes the location from the following list.
Location / application Recommended

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 "SilverCrest Smart-Audio" 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 multiroom devices can be connected to a network. Furthermore
the multiroom devices and your smartphone/tablet must be connected to the same 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 briefly lights up green) only the blue LED flashes slowly. If the
LED does not flash, the speaker must be reset: Press and hold the WPS / RESET button for
approx. 5 seconds to restart the device.
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.
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.

to the WiFi network.
When you use it for the first time, the device starts in AP mode. Otherwise, hold the
WPS / RESET button for approx. 5 seconds to restart the device. After a brief
initialisation period (yellow and blue LEDs on simultaneously, then one LED briefly
lights up green) only the blue LED flashes slowly and the device is in AP mode.
Start the SilverCrest Smart-Audio App and select “Set up audio system”. Follow the on-screen
instructions to connect the device to your WiFi network.
After setup is finished, you can add more existing WiFi devices to the network in the same way, if
you have any.
