Operation Manual

Handling NFC: Turn on the speaker. Bluetooth works spontaneously. Go to the NFC
function of your Bluetooth enabled mobile phone. Put the mobile phone and the induction
zone of the speaker close together to enable Bluetooth of both devices. When pairing them,
the mobile phone beeps, indicating the connection. To disable Bluetooth on the devices, put
them head-to-head. The mobile phone beeps indicating disconnection.
Charging: Plug the cable into the Line–IN slot, USB slot of PC or another USB slot of
chargers to charge the speaker. When the speaker is being charged, the indicator light turns
to RED. Once it is fully charged, the indicator light turns off. (It is recommended to turn off the
speaker while charging, because it will take longer time to get completely charged if the
speaker works while charged.)
