Voice Alarm Precautions

If voice memory contents are 15 seconds long, for example, the alarm operation takes a total of 16 seconds, so two alarm operations are performed for a total of 32 seconds. � If a single alarm operation takes more than 20 seconds, it is performed only once. � The voice alarm does not sound in the Stopwatch Mode. When an alarm time is reached while the watch is in the Stopwatch Mode, the standard beeper alarm sounds even when the voice alarm is turned on.
