Setting the jumpers at the deactivation unit - VdS shunt lock

Jumper B1

The deactivation unit ignores jumper B1. It doesn't matter how jumper B1 is inserted.

Jumper B2

Insert jumper B2. This will maximise the range and improve the connection between the deactivation unit and its locking device.

Jumper B3

Do not plug in jumper B3.
