A5 (blue): +12V: switching voltage output (max. 0.5 A). When the device is turned on, the
switching voltage adjoins contact A5 and serves to retract or extract an automatic antenna and
as operational voltage for antenna amplifiers.
A7 (red): Connection for +12V trigger voltage. Connect to terminal # 15 of the vehicle.
If contacts A4 and A7 are switched, the device will "forget" the stored stations after the ignition
is turned off.
A8 (black): Attach the connection for the ground (diameter at least 2.5 mm) to terminal # 31
(ground) of the vehicle.
Depending on the manufacturer, the contacts on your vehicle connection may be assigned
differently. This is not a defect of the device but caused by a deviating connector pin
assignment by the manufacturer of your vehicle. To provide a connection that conforms to this
device, please purchase an appropriate adapter cable from a specialised dealer if required.
Please consult a specialist in your area if you have any questions about the connections.
