If F2 is behaving unexpectedly or you simply wish to restore it to its original settings, then you can reset it. You may then proceed with pairing F2 again.

Pairing F2 with a device

1. Turn on your F2 by holding the power button for 2 seconds. 
2. Go into the Bluetooth settings on your device. F2 will automatically be in pairing mode and the light on the far left will start flashing white/orange.

Device compatibility

F2 uses Bluetooth version 5.3 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 F2 and connected device away (outdoors or to a different room) to see if the interference clears.

F2 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

F2 does not support multipoint but it has a broadcast function and can broadcast to up to 100 F2 speakers.

F2 is a device with a level 7 water protection rating, which means that the speaker is water-resistant. At this level, the speaker can handle exposure to low-pressure water jet spray. IPX is an official rating that is awarded by an assessment conducted by a third party organization.

IPX7 water protecting allows you to enjoy music in the shower, kitchen or even outdoors.

While it has a great water protection feature and is built for all kinds of weather, we do not recommend soaking it into water.

It may cause water damage and we are unable to cover this kind of case under warranty.
