FOOTBALL STOPWATCH
This stopwatch can be used to time a football match, and even allows for stoppage time.

To set the match time
1. In the Football Stopwatch Mode, hold down the R button for about two seconds until the minute digits of the
match time start to flash. This is the setting screen.
2. Use the C (+) button and A (–) button to change the match time setting in one-minute increments.
• You can set a match time of 1 to 99 minutes. There is also a “– –” setting which means that the match time is
unlimited.
• Holding down the C or A button scrolls at high speed.
3. After the time setting is the way you want, press the R button to exit the setting screen.

To time a match

• Press the C button to start timing of the match in the upper and lower display areas (“Football” flashes on the
display).
• Press the C button again to stop match timing in the upper display area (“Football” stops flashing). The match
timing in the lower display area continues at this time. Pressing C again will resume timing in the upper display
area.
• The stopwatch will beep for 10 seconds when the preset match time is reached in the lower display area. The
lower display area will start measuring elapsed time from zero and the upper display area will continue measuring
time. The end of stoppage time is reached when the upper display area indicates the preset match time.
• To stop match timing, make sure that match timing is stopped (“Football” not flashing), and then hold down the A
button until the watch beeps and the current time appears in the lower display area.

• You should have the rubber seal that keeps out water and dust replaced every 2 to 3 years.
• Should moisture appear inside the stopwatch, have it checked immediately by your dealer or a CASIO distributor.

you record 100 times, the 100th time will not be stored in memory until you reset the stopwatch to all zeros.
• Starting a new stopwatch elapsed time operation will cause the older of the two record groups to be deleted
automatically in order to make room for a new group of records.
• There is also a FAST LAP record that displays the fastest lap from among all of the lap times currently in memory.
• Record 1 (the newest record) will always be displayed first whenever you press the R button to switch from the
Stopwatch Mode to the Recall Mode.
• In the Recall Mode, each press of the B button will toggle the display between record group 1 and record group
2.
• Lap time records in memory can be recalled while an elapsed time operation is in progress or stopped.
• Memory records are cleared whenever a new Stopwatch Mode elapsed time operation is stared by pressing the
C button after pressing the A button to reset the stopwatch to all zeros.

1. In the Alarm Mode, use the C button to scroll through the alarm screen
(1 through 12), until the one you want to set is displayed.
2. Hold down the R button for about 2 seconds until the hour digits of the alarm time start to flash.
3. Use the B button to move the flashing between the hour and minute digits. Use the C (+) and A (–) buttons to
