Reads the contents of the memory location : 2MSB’s to the MS counter, next 2 MSB’s
to the band counter next 12 MSB’s to the tuning counter and D/A and LSB to skipflag
register. Initiates an on command onlyafter standby.

Commands the M494 to wait for a 0-9 program command or to reset on any other
command. Display shows half digit and g segment flashing at 5Hz. Initiates an on
command only after standby.
Increments up or down the relevant analog control counter every keystrobe or
continuously every 112ms from KB and every 102ms from the RC and datainputs. The
display shows an up/down arrow for 300ms min.

Increments up or down the tuning counter. The speed or increment/decrement is
defined by Figure 10. The display shows an up/down arrow for 300ms min.
The program number (memory location) is incremented/decremented.
Volume Mute. See mute section.
Commands the standby state.
Commands the standby statefrom the on state and the on state from thestandby state.

Commands the on state when in the off stateand commands the off state when in the
on state. See standby section.
The currently addressed memory location is written from the tuning, band and MS
counters and the skip flag is reset. See fig. 11. Execution of this command is indicated
by the display flashing at 5Hz for 1 second.
The analog control memories are written in sequencefrom theanalog control counters.
Execution of this command is indicatedby the display flashing at 5Hz for 1 second.
Command the next band in the sequence as defined in bands outputs section. One
step for each key strobe.
Increments the MS counter by binary one. One step for each key strobe.
Reads the analog memories in sequence to their corresponding D/A’s. The analog
control outputs are disabled during the read sequence.
Strobes the program selected immediately after the memory addressing command
(post tuning program selection). See Figure 12.
Sets the skip flag on the currently selected program. Execution of this command is
indicated by the display flashing at 5Hz for 1 second.
Defeats the functionof the skip bit to allow reading and writing of the currently selected
program.
