8. Protection circuit
In order to prevent damage by inadvertently driving with a folded-up
external unit, the black line of the voltage supply of the receiver must be
connected to "pin 15" (pin 15 is a line which does lead voltage during
switched-on ignition and no voltage with switched-off ignition). The unit
will then automatically retract as soon as the ignition is switched on.
In addition, the unit cannot be extended with switched-on ignition.
Note:
Use for the connection only a switched plus wire, not the D-plus line of
the generator. With many vehicles, the D-plus line does not switch
through a clean DC voltage; in addition there are not immediately
available approx. 12 volts on this line but often a voltage is only slowly
built up. This can lead to functional problems with the processor in the
receiver.
9. Mounting the dish antenna
After now all devices have been connected, next the dish antenna will be
mounted.
Attention:
First make sure that within the range of the external rotating
unit no tools or the like prevent rotary motions of the system.
a) Switch on the control unit with the
key. The external unit must now
extend.
b) When the external unit is in approximately vertical state, interrupt the
movements by pressing the key
.
Absolutely wait until the system does not move any longer before you
start with the assembly of the dish.
Now the antenna dish should be bolted onto the dish arm with the four
Philips bolts and lock washers.
