by pressing any button.
• An alarm does not sound if its preset time is reached while an IR data
communication operation is in progress.
Important!
• Infrared is an invisible type of light that travels
in a straight line. Because of this, the IR ports
of two devices that are trying to communicate
must point directly at each other.

can exchange data without any problem, be
sure that you and the person with whom you
are communicating follow the steps outlined
below.

USER’S GUIDE 2496
• 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”.
• Data exchange can take up to six seconds. During that time, keep the IR
ports pointed at each other and avoid moving the watches.
5. Both watches beep to indicate when data communication is complete.
• After data communication is complete, the message OK! appears on the
receiver display for about five seconds. Next, the watch displays the data
that it received.
• If data communication is not successful for some reason, the watches beep
and display the message ERROR! for about five seconds. After that the
receiver enters the Timekeeping Mode. If this happens, perform the above
procedure again from step 2.
To send data to another watch (sender operation)
1. Enter the mode (Data Bank Mode or Mail
Mode) that contains the data you want to
send, and display the data.
2. Hold down E for about two seconds.
3. When the watch beeps, release E. This
causes the SEND indicator to appear on the
display.
• At this point, your communication partner
(the receiver) should also be setting up to
receive.
4. Point the sender’s IR port at the receiver’s IR
port, so the watches are face-to-face. Data
communication should start automatically.
• Data communication can take up to six
seconds to complete. Keep the watches still
until they both beep.
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 REC (receive) indicator to appear
on the display.
5. Point the face of the receiver towards the
sender, and perform steps 6 through 8 on the
sender.
6. On the sender watch, hold down E for about
two seconds.
7. When the watch beeps, release E. This
causes the SEND indicator to appear on the
display.
8. Point the face of the sender at the face of the
receiver, so they are face-to-face.
• User information data exchange starts at
this time.
• Data exchange can take up to 11 seconds. During that time, keep the IR
ports pointed at each other and avoid moving the watches.
9. Both watches beep to indicate when data exchange is complete.
• After data exchange is complete, the watches beep and the message
OK! appears on the displays of both watches for about five seconds.
Next, the watches enter the Data Bank Mode, each showing the data they
just received.
• If data exchange was not successful for some reason, the watches beep
and display the message ERROR! for about five seconds. If this
happens, perform the above procedure again from step 1.
Communicating with Another Watch
Use the following procedures to exchange Data Bank Mode data and Mail
Mode messages with another watch. In this configuration, one watch is the
sender and the other watch is the receiver.
• When a watch receives a mail message, the message text is stored in page
Px4 of the Mail Mode.
To receive data from another watch (receiver operation)
1. Press C to enter the Timekeeping Mode.
2. Hold down B for about two seconds.
3. When the watch beeps, release B. This
causes the REC (receive) indicator to appear
on the display.
4. Point the face of the receiver towards the
sender, and have your partner perform the
sender operation.
• Data communication starts at this time.
• After data communication is complete, the message OK! appears on the
sender display for about five seconds. Next, the watch displays the data that
it sent.
• If data communication is not successful for some reason, the watches beep
and the message ERROR! appears for about five seconds. After that the
sender display shows the data you selected to send in step 1, above. If this
happens, perform the above procedure again from step 2.

• Make sure SEND is on the
display of the sender, and REC
is on the display of the receiver.
• Make sure the two IR ports are
no more than 10cm (3.5 inches)
from each other. Communication
becomes more stable the closer
the IR ports are to each other.
• Make the two IR ports are
pointed straight at each other.
• Align the IR ports of the two
watches within 10 seconds after
SEND appears on one watch
and REC appears on the other
watch.
• Keep the IR ports of the two
watches pointed straight at each
other until the watches beep.
• Remove the watches from your
wrists and place them on a table
or other surface to keep them still
during data communication.
• See the illustration for information
about how the watches should be
oriented during data
communication. Be sure to
perform each step in order, from
1 to 4.

USER’S GUIDE 2496
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 SEND or REC is on the
display.
• During a user information data exchange operation, if ERROR! appears
on the watch sending data first (the sender) and the OK! appears on 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 OK!,
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 ERROR! message
will appear if you try to receive more Data Bank or User Information data.
After that, the receiver switches to the Data Bank Mode, which shows the
message FULL.

• 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.
Data and Setting Scrolling
The B and D buttons are used in various modes and setting screens to
scroll through data on the display. In most cases, holding down these buttons
during a scroll operation scrolls through the data at high speed.
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
Press any button to turn off Auto Display.
Cursor
Auto Return Features
2. When the character you want is at the cursor position, press C to move
the cursor to the right.
3. Repeat steps 1 and 2 to input the rest of the characters you want.
• See the “Character List” for information about the characters you can input.
• 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
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
Mode operations
• Inability to perform IR data communication
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
indicator disappears. If it does not
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.

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
