DIFFERENCES

Major differences between the SINCGARS RT and RCU are these:

RCU does not accept FH data; uses that data loaded into the

companion RT

RCU has speaker connection and switch in lieu of RT RXMT and

ANT connectors.

RCU FCTN switch has an intercom (ICM) position in lieu of the RT

remote (REM) position.

RCU SIG display lights when companion RT receives a signal.

RCU [BATT] key on first press provides RCU battery life Indication,

on second press provides RT battery life indication.

If two-wire connecting RCU with RT is cut or disconnected (or RT

FCTN is not set to REM), RCU display shows "OPEN."
