CAR RADIO MUTING (CRM)
The Blue Switch allows muting your car radio when there is an incoming call.
•
Check the user's manual of your car radio and ensure that it has a Mute function. If additional
settings have to be set from the car radio menu, make sure that they are done correctly.
•
Remove the control panel of the car radio.
•
Remove the decorative panel and take the car radio out of the sleeve using the handles.
Disconnect the car radio plug.
•
Connect the wires of the mr Handsfree Blue Switch to the corresponding wires of the car jack
or of the ISO jack of the car radio. Use the contact clips for the connection.
•
Restore connection and installation of the car radio.
3. Blue Switch Pro: Immediately to the car's electronic system via the ISO cable (Optional).
Many cars have their own type of audio connectors. In such case, you will need an ISO2CAR adapter
cable (please check www.iso2car.eu for more details).
•
Disconnect the car radio and power leads.
•
Join the cable according to the connection diagram shown below. If the car radio has a mute
jack, connect the yellow wire of the ISO cable to one of the "mute in" jacks (1, 2 or 3). Refer to
your car radio manual to determine the position of the mute jack.
•
The default connection is "mute 1". In case this is not corresponding with your car radio, your
car radio will not show "mute" on the screen. However, the sound on the speakers will still be
disconnected from your car radio and connected to your carkit during a phone call.
•
The fuses are for (+) plus and (+) ignition. In some cases (e.g. Renault) these fuse holders need
to be swapped.
