INSTALLATION AND ELECTRIC DIAGRAM
To install the equipment, see the installation diagram on page 4.
Avoid leaving visible cables in the cabin to maintain the vehicle’s aesthetics unaffected.
If there are any cables left disconnected, insulate them with tape; disconnected cables
making an undesired contact can cause a malfunction.
Electronic Unit
Place it on a hidden location for aesthetic purposes. Make sure that the
location allows some ventilation to avoid overheating.
Digital Keyboard
To facilitate handling of the equipment, place the keyboard on a location
within the driver’s reach, such as the console of the vehicle. Clean the
surface where the keyboard is to be sticked to ensure an adequate
adherence. Remove the protective liner from the adhesive pad in the back
side and stick it to the surface.
To clean the keyboard, gently wipe it with a dry cloth. Do not use water or
any solvent.
Loudspeaker
When selecting the location for the loudspeaker, keep in mind that this
component is suitable for outdoor use but it is not immersion-proof.
The loudspeaker must be placed as far as possible from the keyboard
(where the internal microphone is located) in order to avoid feedback.
External Microphones
The microphones require an assembly procedure, shown on the next page.
There are two recommended locations to place them, see the installation
instructions on the next page.
Internal Speaker
Locate the speaker out of view, without affecting the sound.
EXTERNAL MICROPHONES INSTALLATION INSTRUCTIONS
Each microphone includes a shell to hold it
in place and protect it from the elements.
Depending on the installation procedure,
it can be more convenient to assemble
microphone and shell either before or after
the wiring.
For instance, if the wiring requires to pull
the cable through a narrow space, it is
recommended to assemble after wiring.
Microphone + shell assembly procedure
1. Insert the cable in the shell by pressing it with your nger. 2.Push the microphone into the shell (do not pull the cable!).
3.Remove the liner from the tape and stick it to the shell. 4.Stick the shell on the selected surface, previously cleaned
with a 1:1 solution of isopropyl alcohol in water.
Recommended spots to install the microphones
There are two recommended spots in the vehicle (see
gure to the left), they differ with regard to ease of
installation and audio reception volume.
You can select a location according to your preferences.
Location A
Inside the rearview mirror.
This location offers the highest
sound volume, yet the most
time consuming installation, as
it requires to take parts of the
vehicle apart.
Location B*
In the gap of the front doors.
Select a surface to place the
microphone, so that it faces to
the exterior from inside the gap.
Once the surface is selected,
the installation is fairly easy.
* WARNING!
On location B, place the
microphone slightly
downward to prevent
damage from water
clogging.

AUTOMATIC FEEDBACK CONTROL (AFC)
If acoustic feedback would occur while PTT or INTER are on (caused, for instance, by the
opening of a door or window), the equipment will detect and automatically x the issue
by decreasing the volume. After the event takes place, the equipment will attempt to rise
the volume back to the level dened by the user, as long as AFC is not triggered again.
ENERGY SAVING FEATURES (Automatic Shut Down, ASD)
Partial Shut Down (PSD)
The equipment constantly tracks the incoming voltage status. If the incoming voltage
drops below 12.6VDC, after 20 seconds of inactivity the equipment activates PSD mode.
This change is indicated by the turning off the keyboard’s backlights. While on PSD mode,
upon pressing any key the respective function will execute normally and the equipment
will return to normal energy consumption mode.
Total Shut Down (TSD)
If the incoming voltage drops below 11.5VDC, after 60 seconds the equipment will
automatically shut down any function and auxiliary load. While on TSD, upon pressing
any key the backlights will blink 3 times and the function controlled by the pressed key
will not execute.
Once the equipment detects that the incoming voltage exceeds 12.5VDC again, the
equipment will return to its normal operation.
