The RCU and RT are connected by a field wire (two-wire) link and separated up to 4 km. There are four main
configurations that may be used:
(1) RCU in manpack, RT in vehicular mounting adapter.
(2) RCU in vehicular mounting adapter, RT in manpack.
(3) RCU in manpack, RT in manpack.
(4) RCU in vehicular mounting adapter, RT in vehicular mounting adapter.
Refer to the following cabling illustrations and perform the following procedure:
Assemble vehicular or manpack (or both) as needed, using the vehicular or manpack radio assembly
If you are assembling a manpack, you MUST use Battery Box CY8523A/PRC.
Set RT FCTN to SQ ON; then connect two-wire. The two-wire is connected to battery box binding posts in
manpack configurations and to vehicular mounting adapter (E1A/E2A or E1B/E2B, depending on the position of the radio
or RCU) in vehicular configurations.
Connect handset or external speaker (if used). If an external speaker is connected to an RCU, use LS685/U
(connected to RCU SPKR connector). Refer to RCU front panel, page 41.
