Function Keys - IFR FM/AM-1200A Operation Manual

The FM/AM-1200S/A Keyboard consists of 24 keys which provide a means of
entering data into the microprocessor to control the frequency of the
signal generator, receiver, duplex generator offset and tone generator
functions.
3-3-1 FUNCTION KEYS
These keys determine what FM/AM-1200S/A function is selected by the
operator. Most keys have a dual function which will select either the
1st order functions (DTMF, TONE, OFFSET and RF) or 2nd order functions
(IMTS, T SEQ, SCAN, DVM, DCS, BAUD,
INT,
STEP, METER, lOPS, 20PS and a
selection of 4 additional options).
1st ORDER FUNCTIONS (Black Lettering on Keyboard)
These functions are used to set the operating parameters of:
Dual Tone Multiple Frequency (DTMF)
Variable Tone Generator (TONE)
Duplex Offset Generator Frequency (OFFSET)
Signal Generator or Receiver Frequencies (RF)
2nd ORDER FUNCTIONS (Blue Lettering on Keyboard)
All second order function keys must be preceded by the ''2ND FUNCT'' Key.
