Operating guidelines
Using the Number options menu item, you are able to select as to whether the HFCK sends the
details of your own number along during an outgoing telephone call or not. Here, you have a choice of
three options: Phone setting, Show number and Hide number.
The telephone settings are set as standard. The display of your telephone number to your conversati-
onal partner depends on the settings of the call number display and/or suppression in the mobile
phone and the storage of the telephone numbers (with the additions *31# to show numbers or #31#
to hide numbers). If you select one of the two other entries in the HFCK the settings in your mobile
phone will no longer be taken into account. Your telephone number will then consistently either be
hidden or sent.
In the DSP menu item you control the settings for every telephone individually as regards the proces-
sing of the audio signals. The HFCK has an integrated digital signal processor (DSP). This serves the
functions of voice recognition and voice synthesis and is activated as standard. Together with the
suppression of background noise and echoes, the DSP guarantees optimum conversational sound
quality for most mobile phones.
Note:
We recommend that you keep this setting.

If the conversational sound quality should fall, however, you can turn off the suppression of back-
ground noise and echoes and leave the DSP devices activated without this function running. Using the
first selection you can also completely deactivate the DSP. If this setting also leads to no improvement,
you can activate the DSP of the telephone.
With the Clear list command it is possible to delete the full telephone list. You are able to assign an
individual Pin code for the Bluetooth connection in the next menu item. Your own code must be at
least four figures long – with a maximum of eight being allowed.
