Electronic Timer

The electronic digital timer (Figure 1-8) can measure time periods up to 19 minutes, 59 seconds.
The timer has a self-adhesive back which holds it to the recessed surface in the door. It is pow-
ered by two replaceable type AG-10 batteries.

To set the timer...
Hold the SET button in. The digital display will increase by one second, pause, then increase at
a rapid rate. When the desired time is near, release the SET button. Then, increase the time one
second at a time by alternately pressing and releasing the SET button until you reach the desired
setting.
To start the timer...
Press the START button. The timer will beep once to indicate the countdown has started. Then,
the timer digital display will sequence backwards one second at a time until the timing period is
over. At the end of the time-out, the timer will beep twice, pause and then beep twice again.
At the end of the sequence, the timer will automatically reset to the pre-selected timeout period.
To reset the timer to 0...or, to reset a blank screen...
Simply press the start and set buttons simultaneously. The digital display will very briefly read
"18:88) and then will step back to "0:00."
