and the 2nd timer starts counting down immediately. When the 2nd timer

by 1 automatically. At any time during countdown pressing A will stop counting.
** If only the 1st timer is set the timer is used as an ordinary countdown timer and will
give 5 times 4 beeps when the set time is up. The 4 digit counter also advances by 1
automatically when the timer reaches zero.
