Reset
The front panel buttons are used to program the counter and to display and set the P1
preset. All the buttons can be disabled by the Keyboard Inhibit input. (see Programming
on page 6).
P1 Preset
The P1 preset can be set at any time. The minimum value possible is 000001. P1 must
be greater than any multiplying prescaler value, or the unit may not operate correctly.

P1
Press SEL, then use the Digit buttons to change P1. The display will flash. Press SEL
again to accept the new value. If SEL is not pressed within 30 seconds of the last
change, P1 will revert to the original value.
