Headset Preset
By default the phone is set for calls to be connected to the
loudspeaker when you answer or make calls by pressing a Line
key, so called Loudspeaker Preset. Also when you dial the number
without lifting the handset, the call is automatically connected to
the loudspeaker.
When you use a headset for your telephone, you can change the
setting to get calls connected to the headset instead, so called
Headset Preset. In Headset Preset mode you can make headset
calls by pressing digits directly (direct dialling). You can also answer
headset calls by pressing a Line key.
Notes:
Independent the type of preset setting, when you lift the
handset, the call is always connected to the handset.
Also handsfree and loudspeaking work as usual, i.e. when
the Loudspeaker key is pressed, the call is temporarily
connected to the loudspeaker.
Activation and cancellation of Headset Preset can only be
done when the telephone is in idle mode.
