About the Vibration Alarm
When the Vibration Alarm is turned on, the watch vibrates instead of sounding an

Stopwatch, and Alarm Modes. The Vibration Alarm ON/OFF setting is applied to all
modes. You cannot make different settings for each mode.
•All explanations in this manual use expressions such as “sounds the alarm” for
alarm operations. When the Vibration Alarm is turned on, these expressions should
be understood to mean “causes the watch to vibrate”.
•Watches with a metal band may produce a noise when a vibration operation is
performed. This is due to vibration of the metal band, and does not indicate
malfunction of the watch.
