About the Vibration Alarm

When the Vibration Alarm is turned on, the watch vibrates instead of sounding an alarm. This lets you use the watch without disturbing others by beeping sounds.

• The Vibration Alarm can be used to replace alarm sounds in the Countdown Alarm, 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.

• This watch returns to the Timekeeping Mode whenever you hold down the C button

for one or two seconds. If you ever lose track of what mode you are in or what you should do next, hold down C to return to normal timekeeping.

• In any mode press L to illuminate the display.
