2.4.5 Post-Installation Checks
2.4.5.1 Voltage/Resistance Checks
Do not attach the RM01 until the following conditions are met.
Install the AMU50 or similar audio management unit and check the following:
a) Check pin <6> for RM01 ground (ground return to AMU).
b) Check pin <5> for chassis ground (less than 0.5 Ω).
2.4.5.2 Power On Checks
Power up the aircraft’s systems.
a) Check pin <1> for RM01 power (5 Vdc from AMU).
Verify normal operation of all functions of the RM01. Refer to the Installation and Operation manual for
the device to which the RM01 is connected for verification of the RM01 operation.
Upon satisfactory completion of all performance checks, make all required log book entries, electrical
load, weight and balance amendments and other documentation as required by your local regulatory
agency before releasing the aircraft for service.
2.5 Adjustments and Connections
The RM01 stores system configuration data for an audio control system such as the DACS. When
installed in the DACS, the configuration data can be modified using the Device Configuration Software
(DevCs) application. Refer to the SM76 AMU50-001 Audio Management Unit Installation and Operation
Manual and the DevCs Installation and Operation manual for information on connection and operation of
the DevCs.
After an RM01 has been programmed using the DevCs, all settings that are essential to aircraft operation
must be verified by a system test in both normal and emergency modes (e.g. direct audio audible to crew,
transmit and receive functions on COM1 and COM2 operate correctly for crew, required intercom
functions operate correctly, etc).
