IMPORTANT NOTE
This stopwatch can store up to 500 split/lap times. 
However please note when there are 5 free mem-
ories left, the icon “FULL” will blink to remind you 
of the nearly full situation. Whenever the storage 
is full, extra split/lap times will NOT be stored into

only be shown on the display but not recorded.
In order for the stopwatch to record the lap/split
