6. Daily Use — Calling, Answering, and Hanging Up
6.1 Headset Controls and Indicators
The Multifunction Button
This button is located near the back of the BH870 Headset. Through a combination of taps, double-taps, short presses, and long presses,
you will be able to execute all of the most-needed functions, including answering a call, hanging up, switching between held calls, and
more. See 6.1 Headset Controls and Signals in this guide for more information.
Headset Visual and Audio Indicators
The BH870 Headset provides status messages using both lights and audio signals. For example, the LED lights various colors to indicate
battery level, incoming calls, on/o operations, etc. Audio signals tell you when you have pressed a button, selected a new target phone,
or changed the volume; in-ear ring tones are also provided. See 6.1 Headset Controls and Signals in this guide for more information.
6.2 The Target Phone Concept
The target phone is the phone to which the audio link for your (outgoing) call is activated when you tap the multifunction button (MFB)
on the headset. You can select a dierent target phone by pressing the headset multifunction button.
The eect of activating the audio link to an idle target phone varies depending on the gesture you use on the headset multifunction
button, on your set-up, and on the features supported by your phone. For mobile phones you can activate voice-activated dialing or
redial. For softphones you can open the audio link and (for some softphones) redial.
If you initiate an outgoing call from a mobile- or softphone, the audio link opens automatically when the phone goes o-hook. This
phone-initiated outgoing call does not aect your choice of a target phone.
For incoming calls on phones with ring detection — as is the case with mobile phones and most softphones —
activating the headset multifunction button accepts the call. When the incoming call ends, the target phone returns to the selected target
phone before the incoming call.
For phones where ring detection is not possible, you have to change the target phone manually before you can accept the call. In this
case, when the call ends the target phone is the phone for which you accepted the call.
For maximum convenience, set the target phone to the phone which you are most likely to use for outgoing calls.
6.3 How to Make a Call
Standard Mobile Phone Dialing
To place a call through your mobile phone, dial the number, and then press the call button on the mobile. On most phones, the audio
link from the mobile phone to your headset opens automatically.
