5.38 Emergency Call Numbers
Up to five different phone numbers may be reserved for emergency calls. These numbers can always be
called even when the phone or key locks are active.
If emergency numbers of varying length are used, care must be taken to ensure that longer
numbers do not begin with the same digits and ordering used by a shorter number. For example, if
124 and 1245 define two emergency numbers, the number 1245 cannot be used because 124 is
always be evaluated and called before the longer number can be entered. However, 5421 and
1256 would be allowed.
Emergency numbers are configured using the WinPDM/Device Manager and setting the value of the
parameter: Settings → Emergency Call Numbers.
5.39 Audio Adjustment
Microphone gain, noise cancelling and side tone can be configured to achieve optimal audio quality for
each working environment through the parameters:
Audio → Normal
• Normal side tone adjustment - Determines how much of the speakers voice that is fed back to the
speaker.
• Normal mic adjustment - Determines the microphone sensitivity, that is, how much sound the microphone
gains.
• Normal speaker adjustment - Determines how much the speaker volume will be increased/decreased. A
higher value increases the speaker gain.
• Two microphones noise cancelling - Determines how many microphones are used for noise cancellation.
− Yes: The noise cancellation is done using two microphones. This is the default value.
− No: The noise cancellation is done using one microphone.
Audio → Loudspeaker
• Loudspeaker mic adjustment - Determines the microphone sensitivity, that is, how much sound the
microphone gains when the loudspeaker is on.
The parameter settings affect the “normal” mode, that is, the wired headset. Bluetooth headset,
handsfree and loudspeaking modes are unaffected.
• Loudspeaker speaker adjustment - Determines how much the loudspeaker volume will be increased/
decreased. A higher value increases the speaker gain.
For configuration of headset audio see 5.40 Headset Configuration, page 53. Changing these parameters
may result in lower sound quality and high sound level. Evaluate carefully before applying.
5.40 Headset Configuration
A headset is recommended if the handset is used frequently or if the user wants to have both hands free.
The headset comes in two versions, that is, microphone on boom and microphone on cable.
5.40.1 Selection of Corded Headset Type
To achieve optimal audio quality with the different headset types, it is recommended to set the
corresponding headset type. The default setting is “microphone on a boom”, which means that the audio is
optimized for using a headset with microphone on a boom. The headset type can be changed as follows:
1. Select Connections → Headset.
