the countdown reaches zero. You can stop timing by pressing B, and
manually reset to the starting countdown time by pressing D.
• Normally, an alarm tone sounds for about 10 seconds when the end of
the countdown is reached. If you use auto repeat with start time of 10
seconds or less, the alarm tone sounds for only one second.
• Frequent use of auto repeat with a short countdown time can reduce
the charge of the storage battery and cause the countdown time alarm
to become disabled, so it does not sound.

watch towards your face.
• The auto light switch must be turned on
(indicated by the auto light switch on
indicator) for it to operate.
