• Note the following important points whenever performing a data
communication operation.
✓ Make sure the two IR ports are pointed directly at each other.
✓ Make sure the two IR ports are within 10cm (3.5 inches) of each other.
✓ Keep the watches still until they beep, which indicates the end of data
communication.
✓ To help ensure the watches remain still, do not try to look at their displays
until they beep.
✓ Align the IR ports of the two watches within 10 seconds after performing
the button operations to set up the sender and receiver.
• In the case of user information, the two watches exchange their information
with each other. See “Exchanging User Information” for more information.
• Data Bank data can be sent one record at a time, while Mail data can be
sent one message at a time. See “Communicating with Another Watch” for
more information.
• If you experience problems with data communication, see
“Troubleshooting”.
Exchanging User Information
In the case of user information, the two watches exchange their information
with each other, just like two people exchanging names, e-mail addresses,
and phone numbers. Received user information is ultimately stored in the
Data Bank Mode.
• The user information that your watch sends to another watch is the data
you have input in the User Information Mode. Before sending user
information, use the User Information Mode to check it to make sure it is
correct.
To exchange user information
1. Decide with the owner of the other watch who will be the sender and who
will be the receiver.
• It makes no real difference which watch sends user information first. The
following operation causes both the sender and the receiver to get the
information of the other watch.
2. On both watches, press C to enter the Timekeeping Mode.
• What you do next depends on whether you are the sender or receiver.
The sender should perform steps 6 through 8, while the receiver should
perform steps 3 through 5.
3. On the receiver watch, hold down B for about
two seconds.
4. When the watch beeps, release B. This
causes the

Note
• This watch does not support IR data communication with any other device
besides another Module No. 2496 watch.
• Do not allow anything to block the path between the two IR ports.
• IR communication may not be possible outdoors or in other areas exposed
to bright light. Best results are obtained under indoor lighting of 500 lux.
• A separate, nearby IR data transfer operation can interfere with the IR data
communication operation of this watch.
• All watch button operations are disabled while
display.
• During a user information data exchange operation, if
on the watch sending data first (the sender) and the
other watch (the receiver), no data is exchanged between the two watches.
Perform the user information data exchange operation again. In the above
case, the receiver switches to the Data Bank Mode after displaying
so you need to change it to the Timekeeping Mode before trying to perform
a new user information data exchange operation.
• When the receiver’s Data Bank memory is full, the

Auto Return Features
• If you leave the watch in the Data Bank, Mail, Alarm or User Information
Mode for two or three minutes without performing any operation, it
automatically changes to the Timekeeping Mode.
• If you leave a screen with flashing digits or a cursor on the display for two
or three minutes without performing any operation, the watch automatically
saves any settings you have made up to that point and exits the setting
screen.

,
Initial Screens
When you enter the Data Bank, Mail, World Time or Alarm Mode, the data
you were viewing when you last exited the mode appears first.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to
59 causes the minutes to be increased by 1. In the range of 00 to 29, the
seconds are reset to 00 without changing the minutes.
• With the 12-hour format, the P (PM) indicator appears on the display for
times in the range of noon to 11:59 p.m. and the A (AM) indicator appears
for times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59,
without any indicator.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar automatically makes allowances
for different month lengths and leap years. Once you set the date, there
should be no reason to change it except after you have the watch’s battery
replaced.
World Time
• The current time in all World Time Mode cities is calculated in accordance
with the Greenwich Mean Time (GMT) differential for each city, based on
the current Home City time setting in the Timekeeping Mode.
• The seconds count of the World Time is synchronized with the seconds
count of the Timekeeping Mode.
• The GMT differential is the time difference between the time zone where
the city is located and Greenwich Mean Time.
• GMT differential is calculated by this watch based on Universal Time
Coordinated (UTC) data.
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire
display to glow for easy reading in the dark. In any mode, press A to
illuminate the display for about two seconds.
• Holding down A to display the setting screen or to switch between Daylight
Saving Time and Standard time in the World Time Mode also causes the
backlight to light.
• The electro-luminescent panel that provides illumination loses power after
very long use.
• The illumination provided by the backlight may be hard to see when viewed
under direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated.
This is due to vibration of the EL panel used for illumination, and does not
indicate malfunction.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery life.
Battery
If battery power goes low while you are inputting Data Bank data or user
information, the data you are inputting may not be saved in memory. Normal
watch operation will return after the
disappear, have the battery replaced.
Always leave battery replacement up to the dealer where you bought the
watch or to an authorized CASIO distributor. Be sure to show the
“Attention dealer or CASIO distributor” information to the person replacing
the battery.
The indicator flashes on the display
whenever battery power is below a certain level.
Low battery power can cause the following
conditions to occur.
• Dim, difficult-to-read display characters
• Failure of the backlight and alarm operations
• Inability of Data Bank and User Information

• Inability to perform IR data communication

LIMIT Indicator
Certain functions consume large amounts of battery power, and using them
too much can cause a sudden momentary drop in battery power. The watch
monitors how much you use these high consumption functions, and displays
the LIMIT indicator whenever it determines you are using them too much.
• Backlight and alarm operation, Data Bank and User Information Mode
operations, and IR data communication are disabled while the LIMIT
indicator is on the display.
• The following are the trigger values for functions that are monitored for
battery usage.
Approximately 90 consecutive backlight, IR data communication, and alarm
operations
Approximately 900 button input tone operations
• The LIMIT indicator disappears from the display after the battery recovers
its normal power level after it has a chance to “rest.”
Attention dealer or CASIO distributor
