NOTE: In case of connecting a second CU (CU2) to the Extension Box, jumpers J1/J2 should be removed in order to disconnect VHF
Ext. Speaker (VHF LS) output from terminals X6-1/2 and make available the CU2 Ext. Speaker (CU2 LS) connections instead.
VHF Ext. Speaker output will be available at terminals X5-1/2.
Connecting only one CU (CU1) and leaving jumpers J1/J2 in circuit provides VHF Ext. Speaker connection available at both X5-1/2 and X6-1/2.
