You can use this watch even as its battery is being charged by exposure to bright
light.

know when exposing the watch to bright light.
If the display of the watch is blank...
If the SLEEP indicator is on the display, it means that the
display is blank because the watch’s Power Saving
function has turned off the display to conserve power.
Power Saving automatically turns off the display and
enters a sleep state whenever your watch is left for a
certain period where it is dark.
• The initial factory default setting is Power Saving on.
• The watch recovers from the sleep state if you move it to
a well-lit area
*
, if you press any button, or if you angle
the watch towards your face for reading.

Countdown Timer
The countdown timer can be set within a range of one
minute to 60 minutes. An alarm sounds when the
countdown reaches zero. The countdown timer has two
modes: auto-repeat and elapsed time, and a progress
beeper signals the progress of the countdown. All of this
makes the countdown timer a valuable tool for timing the
start of a yacht race.
• All of the operations in this section are performed in the
Countdown Timer Mode, which you enter by pressing
C.

Reset Time
You can set a “reset time”, which is a kind of alternate countdown start time you can
recall with the press of a button any time a countdown operation is in progress.
Timer Mode
The countdown timer gives you a choice of two modes: auto-repeat and elapsed time.
Auto-repeat
The auto-repeat mode automatically restarts the countdown from the countdown start
time you set whenever zero is reached.
• The auto-repeat mode is best when timing the starts of match races.
• Even if you start a countdown operation from the reset time, the countdown
automatically restarts from the countdown start time whenever it reaches zero.
• Auto-repeat timing repeats up to seven times.
Elapsed Time
When the end of the countdown is reached in the elapsed time mode, the timer
automatically switches to an elapsed time measurement operation.
• The elapsed time mode is best when timing the speed of yachts during ocean races.
• The elapsed time operation is performed in one-second increments up to 99 hours,
59 minutes, 59 seconds.
Countdown Timer Beeper Operations
The watch beeps at various times during a countdown so you can keep informed
about the countdown status without looking at the display. The following describes the
types of beeper operations the watch performs during a countdown.
Countdown End Beeper
The watch beeps each second of the final 10 seconds before a countdown reaches
zero, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than
the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal
when the countdown reaches zero.
• The countdown end beeper always sounds, regardless of the on/off status of the
progress beeper.
Progress Beeper
The progress beeper actually includes two beepers: a reset time beeper and a reset
period progress beeper.
• The reset time beeper and reset period progress beeper sound only while the
progress beeper is turned on.
Reset Time Beeper
The reset time beeper is similar to the countdown end beeper. When the progress
beeper is turned on, the watch beeps each second of the final 10 seconds before the
countdown reaches the reset time.
Reset Period Progress Beeper
The reset period is the portion of the countdown between the reset time and zero.
When the progress beeper is turned on, the watch emits four short beeps at the top of
each minute during the reset period, and 30 seconds before the end of the
countdown.
