Review at Amazon seems to say the timer can repeat the same countdown each time button is pushed and countdown is activated.

The timer is easy to set. You just set the time, then hit the big
"start/stop" button and the little "H" and "M" on either side of the
timer display flashes. To clear the timer, just hit both the "h" and
the "m" buttons simultaneously
. (so time has to be cleared)
To stop the alarm or to turn off the
timer before the alarm sounds just hit the "start/stop" button.
On the back of the timer, there are 4 different on/off switches:
flashing light alarm, sound alarm, vibrating alarm, and one for
hours/minutes or minutes/seconds.
When I set the timer on my desk, it moved around when the alarm went
off but when I turned off the vibrating function, the timer didn't move
If you need to turn off both the sound and vibrating alarms and use
only the flashing light alarm, the light is quite noticeable by itself
if placed nearby in your line of sight (within a foot or so). This
would be very handy if you're near a sleeping baby! :) But if you clip
it on a breast pocket, I would use both the flashing light and vibrating
alarms. The vibrating alarm does make a sound, but it's not as loud as
the ringing alarm.
