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.

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.

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

•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.
