NFC
NFC (Near Field Communication) is a technology enabling short-range wireless communication between various
devices, such as smartphones and IC tags. The data communication is easily activated by touching the device to the
specific position on the speaker.
Note
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 9 devices and another device is to be paired.
The speaker can be paired with up to 9 devices. If a new device is paired after 9 devices are already 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 PC.
In this case, erase the pairing information of the speaker on your iPhone/iPod touch or PC, 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 this speaker is "0000." If a passkey besides "0000" is set on the BLUETOOTH device, pairing cannot be done
with the speaker.
