Control Radio Set C-11466/ARC-201-(V) or C-11466A/ARC-201A(V)
The Control, Radio Set C-11466/ARC-201 (V) remotely controls the RT-1477/ARC-201(V). The Control, Radio
Set C-11466A/ARC-201A(V) remotely controls the RT-1477A/ARC-201 A(V) . These remote control units
(RCUs) are mounted in the aircraft console and the RT is mounted remotely. One or more RCUs may be used
with each RT, A C-11466 RCU may also be used to remotely control an RT-1476 RT, and a C-11466A may be
used to remotely control an RT-1476A RT. The RCU controls are the same as the controls on the
RT-1476/RT-1476A RT. A connector is on the back of the RCU. Self-test is provided for diagnostic use.
The Battery Box, CY-8515/ARC-201 (V), is intended to provide an alternative to the Hold Up Battery (HUB) in an
RT. It accepts five C-cell batteries. It is wired to connect five batteries in series. The combined output is used as
an external hold up battery for the RT, The battery box and the RT internal HUB can be used together. When used
together, the battery box serves as the primary power source. The battery box and the HUB serve as mutual
backup power sources.
