Pump Priming Cycle

display along with the time left on the Trial for Ignition (TFI).
Pressing the up arrow button adds a minute to the TFI time for a
maximum of 10 additional minutes (press the up arrow button
10 times). Pressing the down arrow button subtracts a minute
from the TFI time.
There is no visual indication for the basic interface control and
the purge timing is limited to five minutes.

Standby Interrupts control operation.
