How do I turn off the alarm for the sportline 228 watch?

SOURCE: Sportline 228 Stop watch

First a common understanding:
Split/Reset Select button = C
Mode button = A
Start/Stop Set button = B

Pressing B and C simultaneously turns the alarm on and off. The little sound waves on the right will appear and disappear.
Press and hold C - the alarm time will appear. You will probably notice a bar on the display under each day of the week.
While still holding C, press A. All the bars should disappear.

That should stop the watch from beeping on the hour. Good luck.

I'm not sure which stopwatch you have, but if it's a 3 button one with Split on the left, Mode in the middle and Start/Stop on the right, try pressing the left and right button at the same time. Hopefully, this will turn it off. The little 'sound waves' should disappear. Good luck.

Press the mode button twice to enter the alarm setting mode, the press the other two button simultaneously to turn OFF the alarm.

The same actions will turn the alarm ON.

Solution #2 is almost correct. There's one change, I fixed it below:

1.In stop watch mode, while holding the RED light button on the top left.Press the mode button on the bottom left.
2. This will bring you to setting the alarm.Press AND HOLD the mode button on the bottom left to bring you to the 'set time' mode.
3.St/stp button (upper right)to move to the next setting. use the Reset button (lower right) to adjust the setting and the mode button (bottom left) to exit.
