This watch is preset with a number of city codes, each of which represents the time zone where that city is located. When setting the time, it is important that you select the correct city code for your Home City (the city where you normally use the watch). If your location is not included in the preset city codes, select the preset city code that is in the same time zone as your location.

• Note that all of the times for the World Time Mode city codes are displayed in accordance with the time and date settings you configure in the Timekeeping Mode.

1. In the Timekeeping Mode, hold down B until the

seconds start to flash, which indicates the setting screen.

2. Press D twice to move the flashing to the Home City

code setting (see the illustration below), and then use C and A to select the code you want.

• Make sure you select your Home City code before changing any other setting.

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the digital time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

• Note that you cannot switch between Standard Time and Daylight Saving Time while

GMT (Greenwich Mean Time) is selected as your Home City code.

1. In the Timekeeping Mode, hold down B until the seconds start to flash, which indicates the setting screen.

2. Press D once to display the DST setting screen.

3. Press C to toggle between Daylight Saving Time ( displayed) and Standard Time (OFF displayed).

4. Press B to exit the setting screen.

• The DST indicator appears on the display to indicate

that Daylight Saving Time is turned on.

Stopwatch

The 1/100-second stopwatch measures elapsed time, as well as lap/split times. You can also store run data in memory.

• All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing D.

Run number

Lap time (hours, minutes, seconds, 1/100 second)

All Zero Clear

Important!

• A “run” is the total elapsed time and all the lap/split times you recorded from the point you start the stopwatch until you stop it. The watch stores each run as a separate memory record.

• The run number that appears on the display whenever you clear the stopwatch to all zeros indicates the number of the next run record that will be created when you perform a stopwatch operation. The watch automatically increases the run number by one each time you store run data.

• “Lap time” is the time spent to cover a specific segment of a race, such as one lap around a track. “Split time” is the time spent from the beginning of a race up to a certain point.

• Pressing B in the Stopwatch Mode switches the positions of the lap time and split time between the middle display area and the lower display area. Arrows appear next to the LAP and SPLIT indicators to show which time is in the middle (up arrow) and which time is in the lower (down arrow) display area.

• The hour of the time currently in the middle display area is indicated to the left of the lap/split number in the upper display area.

• The display range for the middle display area is 9 hours, 59 minutes, 59.99 seconds. For the lower display area, it is 99 hours, 59 minutes, 59.99 seconds.

• The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.

• The stopwatch measurement operation continues even if you exit the Stopwatch Mode.

• The lap/split number is increased by one each time you press E to register a lap/ split time. The range of the number is lap/split number is appear on the display.

• Performing a button operation in the Stopwatch Mode while battery power is low will cause

ERR to appear on the display for about five seconds. The elapsed time

operation will continue, but button operation is disabled for about eight or nine seconds after when ERR appears, which indicates that the lap/split time normally generated by the button operation you performed will not be stored in memory.

• For information about run data, see “Memory Management” below.

Memory Management

Whenever you perform a stopwatch operation, the watch remembers the total elapsed time and all of the lap/split times you recorded during your run. After your run, you have the option of clearing this run data (by starting a new stopwatch operation), or storing it in memory (by holding down A).

• The watch can store up to 500 run data entries. Total elapsed time counts for one entry, as does each lap/split time. This means you could have anything from 500 records of elapsed run times only, to a single record that contains one elapsed time and 499 lap/split times.

• In addition to measured times, run data memory also records the run date, and keeps track of your best lap time during each run. Note, however, that best lap time data is available for 341 runs only.

• The run date and best lap time of each record are not counted as run data entires. Only elapsed times and lap/split times are counted.

• Attempting to store data while there are already 500 entries in memory will cause

to appear in place of the lap/split number. This indicates no new data can be

stored.

• This watch is designed to stop storing data when its memory becomes full. Before starting a stopwatch operation, be sure to delete any data you no longer need in order to ensure there is plenty of memory available.

• You can use the Recall Mode to view run data currently in memory (including unstored data from your last run).

• In the Stopwatch Mode, you can delete the data of a run you have just completed. You can also delete records one-by-one, starting from the newest record currently in memory. For details, see “To delete individual run data records” below.

In the Stopwatch Mode, press A to clear the display to all zeros. Next, hold down B until the currently displayed run number decreases by one.

• If the displayed run number is 3, deleting will cause it to become 2. Now if you start a stopwatch operation, data will be stored as run 2, replacing run 2 data currently in memory. If want to keep run 2 data in memory from being replaced, hold down A until the run number increases by 1 (from 2 to 3 in the above example) before starting the stopwatch operation.

• Repeat the above procedure to sequentially delete run data records, starting from the most recently stored record.

• You can also delete all of the run data currently stored in memory. For details, see “To clear all run data from memory”.

• Note that it may take some time to recall data for a record that includes a large number of lap/split times. This is normal and does not indicate malfunction. The run number flashes on the display while the watch is recalling the data of such a record.

• If battery power goes low while you are recalling run data, display and buttons will become disabled for about three or four seconds. Normal data display will return when battery power recovers.

• Best lap time data is maintained for up to the first 341 run data records only. It is not displayed for the 342nd and subsequent records.

• Pressing B in the Recall Mode switches the positions of the lap time and split time between the middle display area and the lower display area. Note that holding down B for about two seconds will cause all run data currently stored in memory to be deleted.
