IFR FM/AM-1200A

1-4 DATA DISPLAY AND CONTROL FEATURES
Operator interaction with the FM/AM-1200S/A is facilitated through the
following primary data display and control features:
A. KEYBOARD
The Keyboard provides a means of entering data into the FM/AM-
12DOS/A microprocessor, to control the operation of the RF Fre-
quency or Tone Generator functions. The Keyboard is also used to
address the FM/AM-1200S/A programmable functions which utilize the
automatic storage, retrieval and execution capabilities of the set.
All Keyboard functions are described in detail in Section 3.
B. V FD
The Vacuum Fluorescent Display (VFD) is used to display the current
Keyboard operating frequencies associated with the FM/AM-1200S/A
tone generator or RF Frequency functions. The VFD will display any
telephone number selected during DTMF or IMTS functions (Ref. Sec
tion 3), provide a digital readout of the selected range of both
the FREQ ERROR and MODULATION Meters or display Digital Voltmeter
readings.
1-5 GENERATOR/RECEIVER SUPPORT FUNCTIONS
The FM/AM-1200S/A has the following additional operating functions which
are primarily used to support the generate/receive capabilities of the
set:
Digital Voltmeter (Option)
