Main Functions

Switching on and off the device

Once the Speaker FS3 is on, you can choose the playback mode you prefer. To do so, press Playback mode/Voice assistant (4) repeatedly until finding the preferred playback mode. Playback modes will appear in the following order:

Bluetooth --> microSD --> USB --> Audio-in

You will also hear the word identifying each mode.


Playback control

Select a playback mode and you will be able to control all playback functions from your Speaker FS3.

Press On/Off/Play/Pause/Calls (1) to play or pause a song.

Press Volume +/Next (2) or Volume -/Back (3) to adjust the volume level according to your preferences. You will hear a warning sound when reaching the maximum volume.

Press and hold Volume +/Next (2) or Volume -/Back (3) for 2 seconds to skip to the next or previous track.

When using a removable storage unit such as a USB stick or microSD card, you only have to press Playback mode/Voice assistant (4) twice to skip to another folder. To enable shuffle mode, press and hold the very same button for 2 seconds. You will hear a confirmation sound every time you enable/disable shuffle mode.

Important: Bear in mind that you can only manage playback from the connected music player while using the Auxiliary audio input (10).


Bluetooth

To pair your speaker with a Bluetooth device, press Playback mode/Voice assistant (4). Select Bluetooth mode. At this point, the LED indicator (6) flashes blue. You will hear a confirmation sound when the device enters search mode.

Access the Bluetooth settings on your device and search for the Speaker FS3 among the detected devices. Select it to establish the connection. The devices will be connected immediately. You will hear a sound confirming both devices are correctly paired.

Your Speaker FS3 will automatically pair with your source device when you turn the speaker on again, provided that Bluetooth is enabled on the source device.

Your Speaker FS3 turns off automatically after 5 minutes in Bluetooth mode, if not paired with any device.

The Bluetooth wireless connection range is up to 20 metres.


True Wireless Stereo (TWS)

This technology allows you to wirelessly connect a second Speaker FS3 within a maximum distance range of 20 metres to increase power and create a stereo system with separate left and right channels.

To do so, pair one speaker with your smartphone via Bluetooth first. Once you've done this, switch on the second speaker and enable Bluetooth mode.

Press and hold Playback mode/Voice assistant (4) for 2 seconds on both speakers. You will see the Bt symbol flashing quickly on both units. A few seconds later you will hear a sound to confirm both devices have been successfully synchronized.
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.

To disable the True Wireless Stereo function, press and hold Playback mode/Voice assistant (4) for two seconds on any speaker. You will hear a confirmation sound when both units disconnect.

Skip to the next/previous track and adjust the volume from any speaker while TWS mode is enabled. If you turn up the volume on any of the speakers, you will be turning up the volume of both devices at the same time.

Note: This is only possible if Bluetooth mode is enabled. In all other playback modes (USB, microSD or AUX-in) a TWS connection is not possible.


Removable storage units (USB sticks/MicroSD cards)

The Speaker FS3 plays .mp3 and .wav files from 64 GB USB sticks or microSD cards with FAT/ FAT32 file system. Plug the microSD card into the MicroSD card slot (7) or the USB stick into the USB port (8). The speaker plays the contents automatically a few seconds after plugging the storage unit.

If you turn off the Speaker FS3 or select another playback mode, the internal memory will save the moment where you paused playback. This way, music playback will always resume from the last track you listened to.

Press Volume +/Next (2) or Volume -/Back (3) to adjust the volume level according to your preferences. You will hear a warning sound when reaching the maximum volume.

Press and hold Volume +/Next (2) or Volume -/Back (3) for 2 seconds to skip to the next or previous track.

Press Playback mode/Voice assistant (4) twice to skip to another folder.

To enable or disable shuffle mode, press Playback mode/Voice assistant (4) for 2 seconds. You will hear a confirmation sound every time you enable/disable this mode.

Auxiliary audio input

Your Speaker FS3 features an Auxiliary audio input (10) to connect your external devices using an audio cable with 3.5 mm mini jack plug.

Important: It is not possible to manage music playback from the speaker while using this mode. You will have to use the connected music player instead.

The Speaker FS3 allows you to activate your smartphone's voice assistant. You only have to press Playback mode/Voice assistant (4) twice. This way, you will directly activate your smartphone's assistant via Bluetooth.

This function will let you ask questions and use voice commands to perform tasks naturally and easily.

Charging the battery

When the battery level is below 10%, you will hear a sound reminding you to charge it. To charge the battery, plug the USB Type-C end of the provided USB cable into the USB Type-C charging port (9) and the other USB end to any device with a 5 V USB port (PC, USB wall charger, car charger, etc.). The LED of the USB Type-C charging port (9) lights up red and switches off once the charging process has been completed.
