• The constant current terminal +12 V (4) must be connected to a cable that also supplies 12 V permanently
when the ignition is off (terminal 30 of the on-board network). This terminal serves to save the user set-
tings, time, etc.
• The aerial control output (5) supplies a voltage of +12 V when the device is switched on. This cable can
be used for the power supply of an electrical aerial and for the voltage for switching on a car amplifier.
• The ignition terminal +12 V (7) must be connected to a cable that is only live with +12 V when the ignition
is on (terminal 15 of the on-board networks).
Do not connect this terminal to continuous current, otherwise the on-board battery could be
discharged when the vehicle is parked for an extended period of time.
• Connect the earth connection (8) with the vehicle body.
Adhesive techniques which become ever more common and painted metal parts impair the elec-
tric conductivity. Therefore, not every metal part is a suitable earthing point.
