Device compatibility

Femtio uses Bluetooth version 5.0 which is compatible with a wide range of Bluetooth devices. The paired device does not need to be the same version, but similar versions are more likely to maintain a strong connection. 

Signal interference

Some wireless devices may interfere with each others' signals, such as WiFi-routers, smartwatches, other Bluetooth devices, etc. If they operate within the same frequency, you may experience interference such as dropped sound and glitching. The easiest way to locate the cause of interference is by maintaining one connection between devices at the same time or moving your Femtio and connected device away (outdoors or to a different room) to see if the interference clears.

Femtio can be up to a maximum of 10 meters (32 ft) from the paired device, but the connection may break if they are blocked by walls or similar objects. 

Pairing with multiple devices

If you have connected your device to Femtio and want to connect a different device to the speaker, you have to reset the wireless connection first, then pair a new device with Femtio. Please follow the steps below.

1. Turn on Femtio by pressing the power button for 2 seconds.

2. Press and hold the button on the far left for two seconds to reset the connection. Femtio will be disconnected from the device you were using.

3. It is now ready to connect a different device to the speaker. Start pairing with your new device, you can find the pairing guide here

4. Once connected, you can play music using your new device.
