3.2.3 Microphone

Install the microphone so that it is aimed directly at the user, and comes as
close as possible to the user’s m out h. A good place for th e microphone is n ea r
the rearview mirror where the noise level is lower than, for example, beside a
windshield pillar. It is also possible to install the microphone on a sun visor, but
then it will be inconvenient to use the sun visor an d microphone at the same
time. One alternative would be a swan-neck microphone as it can be placed
closest to the user’s mouth.

3.2.4 Cable

Obtain the necessary +-electricity from a suitable place, preferably directly
from the battery of the vehicle. Connect t he fuse chambe r to the +-wire. You
will find the fuse chamber in the installation material bag. Connect the ground
lead to the frame of the car with a short wire.

3.2.5 External Handset HDS-50

Install the external handset the same way as you installed the phone holder.

3.3 HF-FUNCTION

Benefon Sigma Gold offers you two differ e nt han ds free -setups for th e Car Kit
and Office Set: the b ackg ro und noise tuning (CAR KIT/OFFICE S ET TUNING)
and MIC-ERP contrast tuning (CAR KIT/OFFICE SET SWING).

3.3.1 CAR KIT TUNING/OFFICE SET TUNING (theory)

You can set up the activation lev el of the microphone by using the CAR KIT
TUNING option. The level is correct when the microphone path is activated by
voice alone, and not, for example, by background noise in your car or office.

The following figur e s hows you the CAR KIT TUNING s etup process. You ca n
set up the OFFICE SET TUNING following the same procedure.

a. If the CAR KIT TUNING is set too high, your voice (1) will not activate the
microphone path properly, and the pe rson at the other end will only hear
interrupted transmission of speech.

3.3.2 CAR KIT SWING/OFFICE SET SWING (theory)

The four-step CAR KIT SWING/OFFICE SET SWING tuning is used to set the
contrast of the microphone amplification/speaker attenuation swing. In the
following figures the swing position while listening to the Car Kit or Office Set is
indicated by a solid line and the position while speaking into Car Kit or Office
Set the indicated by a dotted line.

a. With a tuning value of 4 it is possible to obtain the smallest difference
between the amplification and attenuation of the microphone and speaker. This
means that the connection is almost bidirectional. If the HF-function easily
creates feedback, decrease the value of the CAR KIT SWING/OFFICE SET
SWING. By turning down the volume it is possible to reduce the occurance of
feedback.

4.0 SERVICE APPLICATIONS

4.1 BeneWin SCA-50

The BeneWin SCM Program for Windows is designed to facilitate maintenance of
phone numbers and u ser settings on Benefon mo bile phones . You can also use your
phone to carry out the commands in the BeneWin Program, but it is handier to pro­cess data using your screen and keyboard - the advantage of the BeneWin Pro­gram. For example, all user set tings are disp layed in a single wind ow , wh ich enab les
you to check at a glance your current settings.

Your personal settings and phone numbers stored on the hard disk can be trans­ferred to the mobile phone whenever necessary. When you travel or use a borrowed
phone, your own settings make the phone feel like your own.

The main functions of the BeneWin Program are divided into two windows: the
BeneWin SCM window, in which you can modify the phone numbers, and the User

window, in which you can modify the phone’s user settings.

4.1.1 Installation of BeneWin program
