Operation Manual

In the DSP menu item you control the settings for every telephone

individually as regards the processing of the audio signals. The HFCK

has an integrated digital signal processor (DSP). This serves the func-

tions of voice recognition and voice synthesis and is activated as stan-

dard. 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. X

If the conversational sound quality should fall, however, you can turn

off the suppression of background 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 tele-

phone 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.

The last menu item in the

Bluetooth

menu is the Multipoint function.

This function can only be activated via the voice control or the Touch-

screen if at least two mobile phone signatures are included in the list of

telephones. Otherwise the commands „MULTIPOINT ON“ and

„MULTIPOINT OFF“ are not available and the selection field during

operation via the Touchscreen is inactive.

Using the Multipoint function, you can operate two mobile telephones

on the HFCK in hands-free mode at the same time. The primary mobile

phone takes priority, which means that only its telephone books, call

lists, voice memos, SMS and possible emails are loaded and ready in

the memory of the HFCK. This is similar to the situation as though only

one mobile phone were connected with the HFCK. If a call is received

on the secondary mobile phone, this call will also be handled via the

HFCK. The voice feedback informs you accordingly as to which mobile

is receiving the call (the first / second telephone).
