Instructions before installation
• What type of switching function does the original central locking system have?
The system must be programmed accordingly, see chapter "Connecting MT400 to the cen-
tral locking system" on page 8.
You will require the circuit diagram for the central locking system to do so. You can obtain this
from your vehicle dealership. There is corresponding information for some vehicle in chapter
"Vehicle-specific data" on page 9.
If no original circuit diagrams are available and you cannot find your vehicle in the table in
chapter "Vehicle-specific data" on page 9, you will need to determine the function of the
control cables that run from the control unit for the central locking system to the vehicle
doors.
A
NOTICE!
Only connect MagicTouch using the control cables for the central locking and not
using other cables.
Connection to other cables than the control cables or using an incorrect circuit plan
can lead to defects in the central locking system and the remote control.
• How long does the central locking system have to be activated for?
The activation time for MagicTouch was set to 0.7 sec. at the factory.
In some vehicles, for example Mercedes, an activation time of 0.7 sec. might not be sufficient
to completely activate the central locking system.
To program the system to 3 sec., see chapter "Programming MagicTouch" on page 17.
5.2 Determining the installation location for the control unit
Select the installation location for the control unit:
• in the vehicle interior,
• not in areas where strong electrical fields could cause interference, e. g. ignition cables or
central control electronics,
• not in the immediate vicinity of other control units, in order to prevent the devices from
interfering with each other (which could cause malfunctions and reduce the range of the radio
remote control),
• not directly next to ventilator nozzles.
5.3 Determining the installation location for the status LED
Select a position on the dashboard.
