ABOUT THE BACKLIGHT
� Press B to illuminate the digital display for about 2 seconds. The backlight is disabled while an input screen (with a flashing setting) is on the display. � The backlight of this watch employs an electro-luminescent (EL) light, which loses its illuminating power after very long term use. � Frequent use of the backlight shortens the battery life. � The watch emits an audible sound whenever the display is illuminated. This does not indicate malfunction of the watch. � The illumination provided by the backlight may be hard to see when viewed under direct sunlight. � The backlight automatically turns off whenever an alarm sounds.

5. After you set the alarm time, press A to return to the Alarm Mode. � The alarm on indicator ( ) is shown on the display in all modes when any alarm is on.

To switch the hourly time signal on and off
1. In the Alarm Mode, press D to select :00. 2. Hold down A until 00 starts to flash on the display. � The above operation also turns on the Hourly Time Signal. 3. Press D to turn the Hourly Time Signal on ( indicator appears above SIG) and off (no indicator). 4. Press A to return to the Alarm Mode. � The Hourly Signal on indicator ( ) is shown on the display in all modes when the Hourly Time Signal is on.

If you press D while the seconds count is in the range of 30 to 59, the seconds are reset to 00 and 1 is added to the minutes. If the seconds count is in the range of 00 to 29, the minutes count is unchanged. 4. While any other digits (besides seconds), are selected (flashing), press D to increase the number or B to decrease it. Holding down either button changes the current number at high speed. � While the 12/24-hour setting is selected, press D to switch between the two formats. � The day of the week is automatically set in accordance with the date. � The date can be set with the range of January 1, 1995 to December 31, 2039. 5. After you set time and date, press A to return to the Timekeeping Mode. � Whenever you change the digital time setting, the hands move automatically until they match the digital setting.

The Stopwatch Mode can record elapsed time and lap times up to 59 minutes, 59.99 seconds. Measured times are automatically stored into memory. If you preset a lap distance, the watch automatically calculates the speed of each lap. � The term �lap time� refers to the amount of time that it takes to complete a specific segment of a race (such as each lap of a track race).

To measure elapsed time
1. Press D to start the stopwatch. 2. Press D to stop the stopwatch. � You can resume the measurement operation by pressing D again. 3. Press A to clear the stopwatch to 00' 00" 00.

To measure lap times
1. Press D to start an elapsed time measurement. 2. Press A to record the time of the first lap. � At this time, the measured lap time stays on the display for about seven seconds, after which the display automatically changes back to the stopwatch time. 3. Repeat step 2 to record more lap times and store them in memory. � The watch can store up to 20 lap times, and so the display shows up to 20 lap numbers. After lap 20, the indicator starts over from lap 1, which indicates that the oldest lap times in memory are being replaced by the newest measured times. 4. Press D to stop the stopwatch and store the final lap time. 5. Press A to clear the stopwatch to 00' 00" 00. � Pressing A clears the lap time to 00' 00" 00, without changing the current lap number. The lap number returns to 0 when you perform the next elapsed time measurement operation with the stopwatch. � For details on the recalling lap times, see �RECALL MODE�. � Lap times are kept in memory until you clear the stopwatch (by pressing A) and then start a new elapsed time measurement operation.

ALARM MODE

About time memories
This watch can store up to 20 lap times per stopwatch operation. Once 20 lap times are stored, pressing A again (record the 21st lap time) replaces the oldest lap time measurement with the newest one. All lap times in memory are automatically cleared whenever you clear the stopwatch to 00' 00" 00 and then start a new elapsed time measurement operation.

About speed calculations

4. While the hour or minutes digits are selected (flashing) press D to increase the number or B to decrease it. Holding down either button changes the current selection at high speed. � While the On/Off setting is selected, press D to switch the alarm on ( indicator appears above ALM) and off (no indicator). � The format (12-hour and 24-hour) of the alarm time matches the format you select for normal timekeeping. � When setting the alarm time using the 12-hour format, take care to set the time correctly as morning (no indicator) or afternoon (P).

Once you preset a lap distance, the watch automatically calculates the speed of each lap (in Kilometers or miles per hour) in accordance with the time measured by the stopwatch. This function is useful in the timing of motor sports events. � You can view calculated speeds in the Recall Mode. � Speeds can be calculated up to 999 (km/h or mph). � You can input or change the length either before or after the timing operation.
