(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:

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.
