ABOUT THE BACKLIGHT
In any mode, press L L L L L to illuminate the display for about two seconds.
• The backlight of the watch employs an electro-luminescent (EL) light, which loses
illuminating power after very long use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The backlight automatically stops illuminating whenever an alarm sounds.
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 mal-
function of the watch.
COUNTDOWN ALARM MODE
The countdown alarm can be set within a range of 1 second
