How to use the headset with an audio cable (line input)?

What does the LED flashing mean?

The indicators show headset status: blue flashes 5 times at power on; alternating blue/red in pairing mode; blue once every 5 seconds in standby; blue once every 2 seconds for an incoming call; solid red while charging; red flashes twice every 7 seconds for low battery.

Can I connect the headset to two phones at the same time?

Yes, the headset supports dual connection. To do this, first pair with the first phone (A), then turn off Bluetooth on A so the headset enters pairing mode. Then connect the second phone (B). Finally, turn Bluetooth back on A and reconnect manually. Both phones remain connected simultaneously.
