Press again to turn the microphone on
Note: It is advised to use this feature instead of putting a call on
hold. A call on hold may be diverted to your operator,
directly or after some time.
If the portable rings or a warning sounds at an inconvenient
moment, e.g. when the battery runs low, you will be warned
by a battery low sound (4 short beeps).
Press shortly to mute the ringing or warning for
the moment
The Ringer off icon turns on to indicate that ringing is
suppressed.
Note: When a warning occurs during a call and you want to
mute the microphone, the first press always mutes the warning
sound. The second press mutes the microphone.
