Recall Mode
Use the Recall Mode to recall and delete records stored
by the Stopwatch Mode.
•Stopwatch records are stored in “logs” that are created
automatically by the watch. See “Memory Management”
for more information.
•The title screen of the newest log appears first
whenever you enter the Recall Mode.
•Log numbers are automatically assigned in sequence,
starting from 01 .
•All of the operations in this section are performed in the
Recall Mode, which you enter by pressing C .
To recall stopwatch records
In the Recall Mode, use
B

•The cumulative total screen shows the total distance since the last cumulative total
distance reset.
•The locations of the lap time and split time (middle or bottom of the display) in the
Stopwatch Record screen are determined by the display format you last selected in
the Stopwatch Mode.
•The BEST indicator identifies the record that contains the best lap time in the log.
•If the watch is configured for the split time in the middle part of the display
time is shown on the Best Lap Time screen in blue. If the lap time is in the middle, it
is shown in red.
•If a best lap time record is deleted automatically when the log becomes full, the
BEST indicator will not be transferred to the record with the next best lap time. See
“Memory Management” for more information about automatic deletion of records.
•The unit of measurement used for the distance calculation depends on the unit you
select for your stride length as shown in the table below

Inputting Basic Data
Basic Data Input Mode lets you specify your stride length
and a stride length unit. The Stopwatch Mode uses this
basic data for calculating distances you cover while
jogging or running.
•The top of the Stride Length screen shows XM in place
of Yn when you have centimeters specified as the
stride length unit.
•All of the operations in this section are performed in the
Basic Data Input Mode, which you enter by pressing C .
Basic Data
You can specify either inches (in ) or centimeters (cm ) as
the stride length unit. The unit you specify for the stride
length unit also determines the unit of measurement used
for the distance value in the Stopwatch Mode and Recall
Mode, as shown below
Stride length
•The following examples illustrate how you can calculate values for this setting.
239 steps required to run around a 330-yard track.
330 (yards)
÷
239 (steps) X 36 = 49.70 (approximately 50 inches)
239 steps required to run around a 300-meter track.
300 (meters)
÷
239 (steps) = 1.255 (approximately 125 cm)
•Be sure to update basic data values whenever the person using the watch changes.
Important!
•You cannot change basic data settings while a Stopwatch Mode time measurement
operation is in progress. Stopwatch operation must be stopped and the Stopwatch
screen must be cleared to all zeros before you can change basic data settings.
•Whenever you want to change the stride length unit, you must first reset the Cumulative
Total screen to zero. See “T
how to do this.
To input your basic data
1. In the Basic Data Input Mode, hold down B until stride
length starts to flash, which indicates the setting screen.
2. Press C to move the flashing between the stride
length and stride length unit (Yn or XM ) settings.
3. Input the basic data values you want.
•While the stride length is selected, use D (+) and A
(–) to change it.
•While the stride length unit is selected, press D to
switch between available units. If you find you cannot
change the unit, press B to exit the setting screen,
and then reset the cumulative total screen (see “T
reset the cumulative total screen”).
4. Press B to exit the setting screen.
