<Notes on button with protector ring>
There are two types of buttons used for the stopwatch function, which vary
depending on the model: the normal buttons and the buttons with protector rings.
The buttons with protector rings can be locked when they are not intended to be
used.
• Before using the stopwatch, check which type of buttons your watch has. If your
watch has buttons with protector rings, it is necessary to unlock the buttons before
using the stopwatch and to relock the buttons after using the stopwatch. To unlock
