The cable that comes out of the screen unit is used for connecting the screen unit to the handsfree unit. Make sure that the
cable is placed so that it will not be damaged (e.g. not laid under car seats or over sharp edges).
MICROPHONE (M1)
Mount the microphone close to the user’s head (30 cm is optimal) and place it so that it is directed towards the mouth.
Experience has shown that the best location is near the rearview mirror or to the left of the sun visor. To avoid echo, it is
recommended to have a minimum distance of 1 meter between the microphone and the handsfree unit.
Make sure to mount the microphone so that it is not exposed to air streams from the vents. Do not lay the microphone cable
in the heating, ventilation or AC systems. Fix the microphone using Velcro.
CONNECTING TO THE POWER
There are 3 ways of connecting the Blue Compact to the car’s electronic system:
1. Plug & drive connection: Via the adapter for the cigarette lighter (SC3) (Optional).
2. Built-in connection: Immediately to the car’s electronic system via system cable SC2 (Optional).
The wires of cable SC2 are color-coded. They are listed in Table 1 in column A and each wire should be connected to
the corresponding item listed in column B.

Attention!
If there is no “Ignition” wire or if it is unavailable, you should connect the blue cable wire to the red wire of the handsfree
unit and the red cable wire to the “Continuous” wire of the car which keeps the voltage when ignition is turned off. In
this case, the phone call will not be disconnected if the ignition is turned off.
