Once BLUETOOTH devices are paired, there is no need to pair them again, except in the following cases:
Pairing information has been deleted after repair, etc.
The speaker is already paired with 8 devices and another device is to be paired.
The speaker can be paired with up to 8 devices. If a new device is paired after 8 devices have already been paired, the paired device with the
oldest connection time is replaced by the new one.
The pairing information with the speaker has been deleted from the BLUETOOTH device.
The speaker is initialized.
All pairing information will be deleted. If you initialize the speaker, it may not be able to connect your iPhone/iPod touch or computer. In this
case, erase the pairing information of the speaker on your iPhone/iPod touch or computer, and then perform the pairing procedure again.
The speaker can be paired with multiple devices, but can only play music from one paired device at a time.
The passkey of the speaker is "0000." If a passkey besides "0000" is set on the BLUETOOTH device, pairing cannot be done with the speaker.
When an audio cable is connected to the speaker's AUDIO IN jack while the speaker and the BLUETOOTH device have been connected via
BLUETOOTH connection, sound from the BLUETOOTH-connected device is not output from the speaker (the hands-free function is available). To
listen to music from the BLUETOOTH device, disconnect the audio cable from the speaker's AUDIO IN jack.
