Display Tab
Audio Tab
The Echo cancellation option reduces audible echo for callers. An echo will be heard if a speaker and a
microphone or a badly suppressed headset is used. If this option is activated, the microphone is suppressed,
or for hands-free calls it is muted during calls via the receiver as soon as the caller speaks.
This tab is not available for the version of the
Comfort Pro P 300/500 PC which does not have an interface.
Select the desired interface from the Skin selection and the
Device type.
Activate the Truecolor version for optimal display quality. This
option is only available if the graphic card allows for a colour
depth of 16 bit (65536 colours) or more.
You can also stipulate that the Comfort Pro P 300/500 PC is
automatically shown in the foreground of your PC screen when
you have an incoming call. To establish this setting, activate the
Popup an incoming call option. In Windows 2000 and
Windows XP, a Tooltip is also displayed in the task bar.
Select the sound card for the audio input and output. The selec-
tion is necessary if multiple sound cards or sound-card drivers
are installed. The settings for input and output must refer to the
same device. When using DirectSound too, the same device
must be selected for input and for output in the system’s sound
and multimedia settings.
You can also specify which connected device emits the ringing
tones, e.g. a connected headset or a speaker connected to the
sound card.

12
Configuring the Comfort Pro P 300/500 PC Output volume Tab
The Local echo option is only available if your sound card supports the direct output of microphone data to
the speaker. This means that speech is played back without delay in suppressed form on your speaker, in the
same way that it is on your telephone. This option is only recommended if you are using a headset.
The Use DirectSound option allows multiple applications to output acoustic signals simultaneously. This
means that you can use the Comfort Pro P 300/500 PC while playing music data, for example. Deactivate this
option if you experience problems with the input and output of audio data.
Output volume Tab
Input volume Tab
Click on Test and the ring tone will be played. Move the slide

Operation Using the Comfort Pro P 300/500 PC with an Interface
Operation
The Comfort Pro P 300/500 PC can be used with a mouse or keyboard of any workstation computer, in a
manner similar to a Comfort Pro P 300 or Comfort Pro P 500.
When making entries via the keyboard, please note the terminal’s input mode, which distinguishes between
numeric and alphanumeric input. If, for example, you enter a call number you are in numeric input mode.
When you search for a name in the telephone book, you will be in alphanumeric input mode. To enter a “C” on
the terminal, for example, you have to press the “2” key three times. When the letter “C” is entered on the key-
board, the Comfort Pro P 300/500 PC automatically converts it to the corresponding digit key. Always use
your workstation computer’s number pad to enter digits in numeric input mode.
Press the shift key on the workstation computer together with a second key to enter a long key-press on the
Comfort Pro P 300/500 PC. For example, the Comfort Pro P 300/500 PC’s ABC key has the telephone book
(“short”) and language selection (“long”) functions. You can open the telephone book by using the Ctrl+A key
combination. With the key combination Shift+Ctrl+A you reach the language selection.
The following table describes the assignment of the workstation computer’s keyboard to the
