Setting & Resetting the Clock
To set clock, turn the adjustment knob in the back door until the clock
face shows desired time. The adjustment knob controls the black min-
ute hand only. The red second hand is controlled by the Start/Stop but-
ton. Use the Start/Stop button to move it into desired starting position.
Normally, users set the clock back to zero before use. Alternatively,
you can set the clock to a specific time
to provide a timing interval.
(For example, to time a 20 minute
interval, set the minute hand
at 40 and start the clock.
When the clock (minute
hand) reaches 60, your
20 minute interval is up.)
