This watch is preset with a number of city codes, each of
which represents the time zone where that city is located.
When setting the time, it is important that you select the
correct city code for your Home City (the city where you
normally use the watch). If your location is not included in
the preset city codes, select the preset city code that is in
the same time zone as your location.
• Note that all of the times for the World Time Mode city
codes are displayed in accordance with the time and
date settings you configure in the Timekeeping Mode.
1. In the Timekeeping Mode, hold down B until the

Stopwatch
The 1/100-second stopwatch measures elapsed time, as well as lap/split times. You
can also store run data in memory.
• All of the operations in this section are performed in the Stopwatch Mode, which you
enter by pressing D.
Run number
Lap time (hours,
minutes, seconds,
1/100 second)
All Zero Clear
Important!
• A “run” is the total elapsed time and all the lap/split times you recorded from the
point you start the stopwatch until you stop it. The watch stores each run as a
separate memory record.
• The run number that appears on the display whenever you clear the stopwatch to all
zeros indicates the number of the next run record that will be created when you
perform a stopwatch operation. The watch automatically increases the run number
by one each time you store run data.
• “Lap time” is the time spent to cover a specific segment of a race, such as one lap
around a track. “Split time” is the time spent from the beginning of a race up to a
certain point.
• Pressing B in the Stopwatch Mode switches the positions of the lap time and split
time between the middle display area and the lower display area. Arrows appear
next to the LAP and SPLIT indicators to show which time is in the middle (up arrow)
and which time is in the lower (down arrow) display area.
• The hour of the time currently in the middle display area is indicated to the left of the
lap/split number in the upper display area.
• The display range for the middle display area is 9 hours, 59 minutes, 59.99 seconds.
For the lower display area, it is 99 hours, 59 minutes, 59.99 seconds.
• The stopwatch continues to run, restarting from zero after it reaches its limit, until
you stop it.
• The stopwatch measurement operation continues even if you exit the Stopwatch
Mode.

• 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
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.

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

About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, whenever you position
your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.

Auto light switch precautions
• Wearing the watch on the inside of your wrist and movement or vibration of your arm
can cause the auto light switch to activate and illuminate the display. To avoid
running down the battery, turn off the auto light switch whenever engaging in
activities that might cause frequent illumination of the display.
More than 15 degrees
too high
• Static electricity or magnetic force can interfere with proper operation of the auto
light switch. If illumination does not turn on, try moving the watch back to the starting
position (parallel with the ground) and then tilt it back towards your face again. If this
does not work, drop your arm all the way down so it hangs at your side, and then
bring it back up again.
• Under certain conditions, illumination does not turn on until about one second after
you turn the face of the watch towards you. This does not indicate malfunction.
• You may notice a very faint clicking sound coming from the watch when it is shaken
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
, , and Messages
• Performing any button operation that stores or recalls run data will cause to

Normal operation will return when battery power recovers.
• When the AC (all clear) operation is performed after the watch’s battery is replaced,

which is causing improper contact inside the watch. Whenever the message
appears on the display of the watch and stays there, take the watch to the store
where you purchased it or to your local CASIO distributor.
• Performing the AC (all clear) operation will cause all data currently stored in watch
memory to be deleted. Be sure to always keep separate written copies of all
important data.
