USING TWO MASTERS
Two masters can be used in situations for example where a main house and a granny
flat require to be connected in terms of communication but independent in terms of
radio operation.
In this situation one master remains on the standard code setting of ‘1’ and the other
master is set to No ‘2’ by means of changing the jumper settings of L2 and L3 on the
main board. Location of Jumpers L2 and L3 are shown below.
