What should I do if a Bluetooth device cannot connect or has poor audio quality?

If a device cannot connect, check that Bluetooth is enabled on your device; if the PartyBox is already connected to another device, press and hold the Bluetooth button to disconnect and pair with a new device. For poor audio quality, move the device closer to the PartyBox or remove any obstacles between the device and the speaker. The maximum paired device memory is 8 devices, with the ninth device replacing the first. (Page 8)
