RESPONSE TO ERROR MESSAGES
Error messages are shown on the alphanumeric display. In many cases error
messages indicate problems that do not necessarily interfere with
communications. With the exception of error messages "err1, err2, and err3",
which indicate problems with the actual memory program and require higher level
maintenance, all error messages can be cleared from the display by depressing
the CHANGE button. This does not correct the problem, it only clears the error
message(s) from flashing on the display. Prior to any action taken to correct the
problem, the condition on the display should be noted, then the MCS cycled to
OFF, then back to the appropriate program, PROG 1, PROG 2, or PROG 3. If
the condition remains operator troubleshooting (refer to Chapter 3) should be
accomplished. If the condition still exists after operator troubleshooting then refer
to higher level maintenance.

COMMUNICATING FROM AN FFCS
A crewmember wearing a headset connected to an FFCS has the ability to
transmit and receive on a selected radio and/or intercom (WORK switch), while
monitoring 1 additional or all on-board radio(s) (MONITOR switch), subject to the
radio access levels programmed into the MCS. Additionally, the FFCS allows the
capability to select transmission modes as determined by the INTERCOM switch.
The positioning of the headset or vehicle PTT switches can also determine
transmission modes. The table below shows various switch setting combinations
provided by the FFCS.
