6. Installation of the loudspeaker switch box AC 5120
With the AC 5120 speaker switch box, you get the possibility of being able to mute the feedback of your
car radio / CD player etc. and to transfer the voice output of your conversation partner during a tele-
phone call to your vehicle’s speakers. This means that the installation of additional speakers isn‘t re-
quired. If your radio has a mute function, then the vehicle speakers are turned onto mute using the
radio. If your car radio doesn‘t have this function, then the signals will be suppressed by the speaker
switch box. You can use the AC 5120 through the connections that your BURY hands free car kit offers,
which guarantee voltage supply via molex plugs and also have a speaker output.
If you want to make a telephone call in the hands-free mode, your car radio will be automatically
switched on to mute. The Audio switch box now uses one or two loudspeakers in your car for the tel-
ephone conversation, even if your radio is switched off. This function will be automatically activated
after the installation of the unit, there are no subsequent manual settings required.
Some mobile phones do not support a radio mute function. Please read your telephone user manual
for more details. You can find out more detailed information at your specialist retailer, in the internet
under www.bury.com, or over our telephone hotline.
After checking that all the cable lengths are sufficient, decide where you are able to attach the Audio
switch box. Now secure the Audio switch box so that it isn’t able to flap about and/or rattle against
other parts of your vehicle.
Connect the white power out cable connector (1) of your Audio switch box to the power supply socket
of your hands-free kit. Now connect the audio switch box plug (4) to the hands-free car kit. (The other,
smaller box is used by the plug for the microphone.)
