Multi Pairing
Multi Pairing Method
1. All Bluetooth devices to be used in multi pairing must be first paired individually using
appropriate profiles. (HSP or HFP for phone conversation, and A2DP for high quality audio)
※Each profile cannot be used to connect more than one device simultaneously. See ‘Notice’ below for more details.
※The auto connect function of the headset will connect each profile to the last connected device.
2. Once the host devices are paired, connections can be made by:
a. Turning the headset off and on (Auto connect function will take effect).
b. Or connecting from host devices.
Notice
1. In multi pairing, one profile cannot be used to connect more than one device. For example, it is
NOT possible to use the phone’s MP3 player and the computer’s MP3 player at the same time,
because both devices try to connect through the A2DP profile. On the other hand, it is possible
to connect the phone using HSP, while the computer is connected using A2DP. This way, you
can listen to the music from the computer and answer phone calls at the same time.
2. In multi pairing mode, the use of some functions maybe restricted depending on host devices and
the environment in which it is used.
3. We do not guarantee the compatibility of all combination of devices and functions for multi
pairing.
Line in /out
You can use the line in cable to listen to music through the stereo speaker from an external
device. To touch and hold Mute icon, you can listen to music and make a phone call using
earphone.
