For the alarm: If you want to use it (I think both it and the light use battery faster than when not used), you set it by pushing mode button twice, as indicated above, then go to hour or minute setting by pushing the lap/reset button, and advance to the time you want by pressing the start/stop button. Pushing mode will take you back to normal time again.

To turn alarm on or off, hold lap/reset button in and at the same time push the start/stop button. Alarm icon will show on or off. When you release the lap/reset button, it will revert to normal time.

If the alarm is on, at the designated time it will start beeping for awhile or until the lap/reset button is pushed (off) or start/stop button (snooze).

1. At the start of the activity, depress button “D” to
start the stopwatch.
2. At the end of the first lap, depress button “A”.
The first lap time and lap number are displayed,
though the second lap time is being measured
internally.

the end of the second lap. The first lap time and
lap number disappear, and the measurement in
progress and “0” are displayed in place of the lap
time and lap number, respectively.
4. At the end of the second lap, depress button “A”.
The second lap time and lap number are displayed,
though the third lap time is being measured
internally.
5. Measurement and release of the lap time can be
repeated by depressing button “A”.
6. At the end of the activity, follow either of the two
methods below.
a. To display the final lap time, depress button
“A”. Then, depress button “A” to release the
lap time, and depress button “D” to stop the
measurement.
* The time displayed when button “D” is depressed
is not the total elapsed time of the
activity, that is, the time that elapsed from
the start until the end of the activity but the
time that elapsed from the start until the
stop of the measurement.

Notes:
1. When a lap time measured is the fastest among
the lap times previously measured, a short beep
rings to signal that the memory has been updated
with the new fastest lap time.
2. The lap number counts up to “9”. After “9”, the
number returns to “1”.
• While a lap time is being displayed, depress button
“B”. With each depression of the button, the

previous lap time is displayed in the following
order.

The selection of the display can be made in the
following order with each depression of button “C”.

* A flashing display mark indicates that the corresponding

- HOW TO USE THE STOPWATCH
• The stopwatch can measure up to 9 hours, 59
minutes, 59 seconds and 99 in 1¤ 100 seconds.
* Even if the stopwatch display is changed to another
while the measurement is in progress, it continues
counting properly. After the stopwatch is used,
however, be sure to reset it as the battery energy
is consumed enormously to shorten the battery
life.

I searched for instructions for you watch but was unable to fins them. If you follow the instructions below, you may (with some experimenting) be able to set your watch.

There should be a button marked "mode". Pressing this button cycles the display through the various setting options that are available on the watch.

The functions are likely to be abbreviated, so you may have to guess what each one means.

When you have reached the time setting mode (TS perhaps?) use one of the other buttons to advance or ****** to time etc.



Good luck.

The crown at 3 o'clock is used to set the time and change modes. The crown at 9 o'clock is used to rotate the flange at the edge of the dial.
The A button at approximately 2 o'clock starts and stops the chronograph function. The B button at approximately 4 o'clock resets the chronograph.

Lap Timer: When the watch is displaying normal time, press the right side crown to switch to chrono mode (the hour hand will indicate CHRONO). This watch measures lap times, press A to start timing the first lap. Press A again to stop the first lap and automatically start timing the second lap (the hour hand will move to indicate you're on the second lap), and so on. You can measure up to 20 laps this way. When you're fininshed timing laps, press the right side crown to see the best lap time. To reset the lap timer, hold down B for 2 seconds. To switch out of chrono and see the normal time, just press the right side crown in.

Chronongraph: To time an interval that is not a lap, just follow the above instructions, but instead of pressing A to stop the first lap, press B and the watch will show the elapsed time to the nearest 1/100th of a second. Hold B to reset.

Crown at 9 o'clock: This crown rotates the inner flange at the edge of the dial and is used to measure total race time (i.e. the total of all the laps). Simply rotate the crown until the the little start trinagle on the flange is aligned with the minute hand. This way, the total elapsed time can be read at any time, similarly to how a rotating bezel works.

To set the time: Ensure the watch is not in CHRONO mode, if so, press the right side crown in. At this time pull the right side crown out until you feel a click.The position the second hand moves to indicates what is currently being set. If the second hand is at 9 o'clock, you are setting am hours, press A repeatedly to set am hours. Then press B and the second hand will move to 6 o'clock, pressing A repeatedly will set the minutes. So on for year (11 o'clock), month (12 o'clock), and day (1 o'clock).

the mode button controls the different functions of the watch.  time, alarm time, stopwatch, timeset, alarmset, in a repeating cycle.  Make sure you are on the time function (seconds ticking and changing every second, but not flashing twice per second.  This is the normal mode that shows the time.
 A press of the lap/reset button (labeled) will show the alarm time, Unpress will show the time of day. Press again toshow the alarm time. Press and hold the lap/reset button will show the alarm time again, but it will hold there.  While holding this lap/reset button, press the start/stop button (labeled). This will turn on (or off) the alarm (tiny indicator).  Press this start/stop button repeatedly (while still holding the lap/reset button and you will see the indicator turning on and off with each press.  Stop this button pressing with the indicator OFF, let up on the lap/reset button, and the time will return to the screen.  The alarm will now be OFF.
