5.3.4 Timer
When operational mode is changed to the timer function, TIMER will be backlit (refer to Figure
11). The timer function can be operated as either an elapsed timer (stopwatch) or countdown
timer, where a specific countdown time can be set. Upon power up, the MD93 remembers
countdown timer setting and, when in timer mode, will default to the last mode (elapsed or
countdown).
5.3.4.1 Elapsed Timer
The elapsed timer counts up to a maximum of 99 hours, 59 minutes, 59 seconds and
then starts again at zero time. Pressing the
+
button will start and stop the timer. Pressing
the
–
button resets the timer only if the timer is stopped. Note: If the timer is active, the
user can change modes (e.g. to local time) and timer will still remain active, but only
when power is maintained to the clock. For detailed timer operation, refer to Figure 12.
5.3.4.2 Countdown Timer
The countdown timer can be set to a maximum of 99 hours, 59 minutes, 59 seconds.
Pressing the
+
button will start and stop the timer. Pressing the
–
button resets the timer
only if the timer is stopped. When the countdown timer reaches 00:00:00, it will begin
counting up and will flash every second to indicate elapsed time after countdown reached
zero. Note: If the timer is active, the user can change modes (e.g. to local time) and
timer will still remain active, but only when power is maintained to the clock. Countdown
timer setting is maintained when clock is powered off. For detailed timer operation and
setting, refer to Figure 12.
