8.Safety / Ignition OFF
The 3-pin power connector holds a third line, colored black. This
is to automatically retract the antenna if the vehicles motor is
started.
The automatic retraction will avoid any damage to the system if
the owner accidentally forgets to switch the system off properly
before starting to travel.
You must connect the brown line to the vehicle's ignition control
line to get this feature working. No special cable diameter is
required, as this line is control only, not a power line.
The control voltage must be > 8V and < 30V.
