2) selection of the cluster-groups’ configuration
There are 9 possible configurations:
Input UHF1 UHF2 UHF3
Cluster-groups
10 0 0
9 0 1
8 0 2
7 0 3
6 0 4
2 6 2
2 5 3
2 4 4

You can enter into these configurations by pressing the “ENTER” key for 3 seconds.
The display indicates the selected configuration: it views the cluster-groups corresponding to the 3
UHF inputs.
Note:
The cluster-group 2 5 3 assigns: 2 clusters to the UHF1 input, 5 clusters to the UHF2 input, 3 clusters
to the UHF3 input .
Each cluster can be programmed for a bandwidth variable from 8 to 48 Mhz. with a 8 Mhz. step, that
means from 1 to 6 UHF channels with 1 channel steps.
