Figure 2 - ATB-300 Priority Memory Programming Mode Display
Pressing the F2/F5 key will enter the memory programming mode. In this mode, the top
line of the LCD indicates the current memory (PRI 1 to PRI 8) being programmed, its
contents and the activity status of that channel. The lower line indicates the channel that
will be programmed into the memory when the ENTER key is pressed along with its
activity status.
The LEFT and RIGHT ARROW keys are used to select a memory to program. The
UP and DOWN keys sequence through the input channel selections. Pressing the
ENTER key will program the channel indicated on the bottom line in to the priority
memory. Note that programming the same channel into more than one memory is
possible and can be done to avoid having an unconnected input in the priority memory
list. The factory default memory channels are programmed to sequence through the 8
possible inputs in numerical order.
