1 To store run data in memory, you need first to press
A
to clear the display to all zeros, and then hold down
A
until the run number increases by 1. If you clear the
stopwatch to all zeros without storing the current run data
(by holding down
A
), the current run data will be deleted
when you start a new stopwatch operation.
*
2 Pressing
E
to perform a lap/split time operation freezes the lap/split time at that
point on the display for about five seconds. After that, the display returns to normal
stopwatch time measurement.
Note
• The lap/split number is increased by one each time you press E to register a lap/
split time. The range of the number is
O1 to 5OO. Pressing E while the current
lap/split number is
5OO or when memory is full with other data causes to
appear on the display.
• Performing a button operation in the Stopwatch Mode while battery power is low will
cause
ERR to appear on the display for about five seconds. The elapsed time
operation will continue, but button operation is disabled for about eight or nine
seconds after
ERR appears. The lap/split number on the display will show --
when ERR appears, which indicates that the lap/split time normally generated by
the button operation you performed will not be stored in memory.
• For information about run data, see “Memory Management” below.
Memory Management
Whenever you perform a stopwatch operation, the watch remembers the total elapsed
time and all of the lap/split times you recorded during your run. After your run, you
have the option of clearing this run data (by starting a new stopwatch operation), or
storing it in memory (by holding down A).
• The watch can store up to 500 run data entries. Total elapsed time counts for one
entry, as does each lap/split time. This means you could have anything from 500
records of elapsed run times only, to a single record that contains one elapsed time
and 499 lap/split times.
• In addition to measured times, run data memory also records the run date, and
keeps track of your best lap time during each run. Note, however, that best lap time
data is available for 341 runs only.
• The run date and best lap time of each record are not counted as run data entires.
Only elapsed times and lap/split times are counted.
• Attempting to store data while there are already 500 entries in memory will cause
to appear in place of the lap/split number. This indicates no new data can be
stored.
• This watch is designed to stop storing data when its memory becomes full. Before
starting a stopwatch operation, be sure to delete any data you no longer need in
order to ensure there is plenty of memory available.
• You can use the Recall Mode to view run data currently in memory (including
unstored data from your last run).
• In the Stopwatch Mode, you can delete the data of a run you have just completed.
You can also delete records one-by-one, starting from the newest record currently in
memory. For details, see “To delete individual run data records” below.
To delete individual run data records
In the Stopwatch Mode, press A to clear the display to all
zeros. Next, hold down B until the currently displayed
run number decreases by one.
• If the displayed run number is 3, deleting will cause it to
become 2. Now if you start a stopwatch operation, data
will be stored as run 2, replacing run 2 data currently in
memory. If want to keep run 2 data in memory from
being replaced, hold down A until the run number
increases by 1 (from 2 to 3 in the above example)
before starting the stopwatch operation.
• Repeat the above procedure to sequentially delete run
data records, starting from the most recently stored
record.
• You can also delete all of the run data currently stored in
memory. For details, see “To clear all run data from
memory”.

Recall Mode
Use the Recall Mode to recall and delete run data stored
by the Stopwatch Mode.
• All of the operations in this section are performed in the
Recall Mode, which you enter by pressing D.
• Entering the Recall Mode displays the newest run
record (the one with the highest run number) first. When
the displayed record corresponds to the run number
shown on the display in the Stopwatch Mode, the run
date will show
x-xx
if you have not performed any
stopwatch timing operation yet for that record.
• The run number shows
xx
x
if there is currently no run
data in memory.
To recall run data
In the Recall Mode, press A to scroll sequentially through run data records, starting
from the newest data (the data with the highest run number). When the run data
record you want is on the display, press C to scroll through the other data contained
in the record as shown below.

• Note that it may take some time to recall data for a record that includes a large
number of lap/split times. This is normal and does not indicate malfunction. The run
number flashes on the display while the watch is recalling the data of such a record.
• If battery power goes low while you are recalling run data,
ERR will flash on the
display and buttons will become disabled for about three or four seconds. Normal
data display will return when battery power recovers.
• Best lap time data is maintained for up to the first 341 run data records only. It is not
displayed for the 342nd and subsequent records.
• Pressing B in the Recall Mode switches the positions of the lap time and split time
between the middle display area and the lower display area. Note that holding down
B for about two seconds will cause all run data currently stored in memory to be
deleted.
To clear all run data from memory
In the Recall Mode, hold down B until CLR appears in the upper display area.
•

will appear in the middle display area to indicate that there is no run data in

• Note that you will be able to perform the above operation only if the stopwatch is
stopped and cleared to all zeros. If the stopwatch is running or displaying an
elapsed time value, go to the Stopwatch Mode and press A to stop it, and then
press A again to clear the display to all zeros.
• You can also delete run data records one-by-one. For details, see “To delete
individual run data records”.

Countdown Timer
You can set the countdown timer within a range of one
minute to 24 hours. An alarm sounds when the countdown
reaches zero.
• You can also select auto-repeat, which automatically
restarts the countdown from the original value you set
whenever zero is reached.
• The initial default countdown start time when you
purchase the watch or after you have its battery
replaced is five minutes.
• All of the operations in this section are performed in the
Countdown Timer Mode, which you enter by pressing
D.
To use the countdown timer
Press E while in the Countdown Timer Mode to start the countdown timer.
• When the end of the countdown is reached and auto-repeat is turned off, the alarm
sounds for five seconds or until you stop it by pressing any button. The countdown
time is automatically reset to its starting value after the alarm stops.
• When the end of the countdown is reached and auto-repeat is turned on, the alarm
sounds, but the countdown starts again automatically whenever the countdown
reaches zero.
• The countdown timer measurement operation continues even if you exit the
Countdown Timer Mode.
• Press A while a countdown operation is in progress to pause it. Press E to
resume the countdown.
• To completely stop a countdown operation, first pause it (by pressing A), and then
press A again. This returns the countdown time to its starting value.
To set the countdown start time
1.In the Countdown Timer Mode, hold down B until the
hour setting of the countdown start time starts to flash,
which indicates the setting screen.
• Holding down B will not change to the setting screen
if the countdown timer is running. In this case, first
press A to pause the timer.
2.Press D to move the flashing between the hour and
minute settings.
3.While a setting is flashing, use C (+) and A (–) to
change it.
• For a 24-hour countdown, set a start time of
0:00
.
4.Press B to exit the setting screen.
To turn auto-repeat on and off
While the countdown start time is displayed on the
Countdown Timer Mode screen, press A to toggle auto-
repeat on (
displayed) and off ( not displayed).
• When the end of the countdown is reached and auto-
repeat is turned on, the alarm sounds, and the
countdown starts again automatically. You can stop
timing by pressing A, and manually reset to the starting
countdown time by pressing A again.
• Frequent use of auto-repeat and the alarm can run
down battery power.
