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.

the watch into 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
the watch towards your face for reading.
It can take up to five seconds for the display to turn on.

How the Stopwatch Works
There are two ways you can use the stopwatch: to measure elapsed time and lap/split
times like a standard stopwatch (see "To measure times with the stopwatch"), and to
keep track of the distance you cover while jogging or running. In order to use the
stopwatch to keep track of distance, you must first perform the steps listed below.
1. Set your basic data. See "Basic Data".
2. Turn on the pacer signal. See "To turn the pacer signal on and off".
Note
In order to obtain accurate distance calculations, you must set accurate basic data
and keep your exercise pace in accordance with the pacer signal emitted by the
watch.
See "How Stopwatch Data is Stored" for information about the type of data the watch
stores in memory when you use the stopwatch.
Use the Recall Mode to view data stored in memory.
You can view distance covered data only by recalling it in the Recall Mode. It does
not appear on the Stopwatch Mode screen.

Note
Pressing D to perform a lap/split time operation freezes the lap/split time at that
point on the display for about eight seconds. After that, the display returns to normal
stopwatch time measurement.
During a stopwatch time measurement operation, the upper part of the display
shows the hour digit and the current lap/split number, the center part shows the
current split time, and the lower part shows the current lap time.
When the pacer signal is turned on, it sounds for the first 30 seconds after you start
a stopwatch time measurement operation. After that, the pacer signal sounds for 30
seconds whenever you press B.
If the pacer signal does not sound even though you have it turned on, press B to
change the positions of the lap time and split time on the display. This should cause
the pacer signal to sound.

the time shown in the lower part of the display is greater than 60 minutes, the display
format changes to show hours, minutes, and seconds. Whenever the time in the
center part of the display is greater than 10 hours, the display format changes to
show hours, minutes, and seconds.
