I am having a problem connecting to my mobile phone while using my Logitech BH870 headset.

If you have problems connecting to the headset it is probably due to:

• Battery lifetime.
• Interference with other Bluetooth devices.

For that reason, a reconnection scheme is implemented in the headset with frequent reconnect attempts just after connection loss. After a period of time, the timeout between reconnect attempts is increased, to preserve battery and to avoid generating excessive RF traffic.

You can at any point restore connection by:

• Pressing the grayed-out mobile phone icon on the display.
• Tapping MFB on headset when mobile phone is in focus.
• Restore headset connection from mobile phone.

Besides that, some mobile phones will try to reestablish the headset connection whenever there is an outgoing or incoming call on the mobile phone.
