2.2.4.
CHANGE SWITCH
The CHANGE switch is used in conjunction with the SYSTEM and PROGRAM
switches to do the following functions:
a. CANCEL ERROR MESSAGES: In normal operating mode with the
SYSTEM switch set on PROG1, PROG2, or PROG3 and the PROGRAM switch
set on SYSTEM, it can be used to cancel error messages (with the exception of
ERRI, ERR2, & ERR3 messages) on the alphanumeric display. The condition
causing the error message still exists but is no longer shown.
b. ALTER BRIGHTNESS OF ALPHANUMERIC DISPLAY: In normal
operating mode with the SYSTEM switch set on PROG1, PROG2, or PROG3
and the PROGRAM switch set on SYSTEM, depressing the CHANGE switch
changes the brightness level of the alphanumeric display. With each depression
of the CHANGE switch, the brightness of the alphanumeric display goes from
high brightness for daytime use (initial power-up of the MCS always starts at this
brightness level), to low brightness for use with a darkened vehicle and night
vision goggles, to shutting the display completely off, then back to high
brightness.
c. PROGRAMMING THE MCS: When the SYSTEM switch is PROG1,
PROG2, or PROG3, the CHANGE switch is used in conjunction with the
PROGRAM SWITCH to define radio access levels of the crewstations.
Depressing the CHANGE switch when the PROGRAM switch is set on
STATION, RADIO, or FUNCTION allows the programmer to scroll through the
crewstations available, radios available, and the function of receive and transmit,
respectively.
