Press Change function (4) until you find Bluetooth mode while your Speaker FS1 is on. At this point, you will be able to
pair the speaker with your smartphone or tablet.
Once your Speaker FS1 appears on your smartphone or tablet screen, press "connect". The devices will be connected
immediately and without codes. You will hear a sound that confirms both devices have been paired correctly.
At this point, you will be able to start playback on your smartphone or tablet. The Bluetooth wireless connection range is
up to 10 metres.
Your Speaker FS1 connects to the last paired device automatically when you switch it on once again, provided that the
Bluetooth connection on your smartphone or tablet is enabled.
Important: Your Speaker FS1 turns off automatically after 5 minutes with Bluetooth® mode enabled, if not paired with
any device.
Call control (Hands-free function)
You can manage your calls from the speaker itself. To do so, pair the Speaker FS1 with your smartphone.
When receiving a call, the song you are listening to stops and the ringing tone sounds instead. Press Call control (1) to
answer an incoming call. Press it once again to hang up.
Important: If you receive an incoming call while TWS mode is enabled, you will only hear the voice of the person who
calls through the speaker connected to your smartphone (left channel).*
TWS (True Wireless Stereo)
This option makes it possible to wirelessly pair another Speaker FS1 to get twice as much power and create a stereo
sound system made up of two different channels: left and right.
To use this function for the first time, turn on your two Speaker FS1 and press and hold Change Function/ TWS (4) on
both speakers for 2 seconds. A few seconds later you will hear a sound to confirm that both devices have been
successfully synchronized. Enable then Bluetooth on your source device and connect your Speaker FS1.
From that moment on, you will be able to play music via Bluetooth. You will hear the music through both speakers at
the same time. One speaker will be assigned the left channel (L) and the other one the right channel (R).
The next time you turn on both speakers, they will pair with one another automatically.
If you want to disable this function, press and hold Change function/ TWS (4) on any of them. Both speakers will be
disconnected. Press the very same button if you want to reconnect them.
Switch to the next/ previous track and adjust the volume pressing the corresponding buttons on any of the speakers
while TWS mode is enabled. If you turn up the volume on any of the speakers, you will be turning up the volume on both
of them at the same time.
Important: This is only possible if Bluetooth mode is enabled. In all other playback modes (USB, microSD, or line-in) a
TWS connection is not possible.

after inserting the microSD card or USB stick.

playback. If you connect the same removable storage unit once again, music playback will resume and the last song
you listened to will be then played.
