You can use your phone’s Stopwatch feature to time an event in hours,
minutes and seconds. The event’s time can be saved, viewed, or erased.
Warning! Your phone must be switched on to use this function. Do
not switch the phone on when wireless phone use is prohibited or
when it may cause interference or danger.
Important: Using the stopwatch consumes the battery and the
phone's operating time will be reduced. Be careful not to let it run
in the background when performing other operations with your
phone.
