3. INSTALLATION
3.5 Safety circuit
To prevent damage from driving with the external unit unfolded, the black cable of the FeatureBox' power supply
must be connected to terminal 15. A line connected to terminal 15 is live when the ignition is switched on and
carries no voltage when the ignition is switched off. The antenna will retract automatically when the ignition
is switched on.
When the ignition is switched on, the antenna will not open.
Note:
For this connection, use only a switched positive line, do not use the D-positive line of the alternator. The
D-positive line of many vehicles does not provide a reliable direct current. Also, this line does not provide the
nominal voltage of 12 Volts instantly, but the voltage may only rise slowly. This may affect the function of the
FeatureBox processor.
