Download the latest FiiO Control App on your phone: download link
After connecting K19 to your mobile phone via Bluetooth, open FiiO Control APP, find FiiO K19 in My Products page and click Connect. After a successful connection, you will enter the Bluetooth control page of K19.
What to do if the phone cannot be connected:
1.Try to restart K19 and connect again
2.It is not recommended to use FiiO Control and FiiO Music at the same time. During Bluetooth high bit rate transmission, if you set FiiO Control, there may be conflicts. It is recommended to use FiiO Music to play music after the setting is completed.
3.Please turn on the location of the mobile phone, turn off the FiiO Control APP, and reconnect it
4. It is recommended to set K19 to Bluetooth working mode first. Open FiiO Control to connect K19 after the mobile phone searches for FiiO K19 device in "Settings - Bluetooth" and connects to it successfully.
