Note

ξThe Stopwatch 1/5-second Hand and Stopwatch Minute Hand move for only the fi rst 60 minutes of an elapsed time operation. After that, they stop at the 12 o’clock position.

ξThe stopwatch will not operate while the second hand is jumping at two-second intervals, which indicates that the watch’s charge is low.

ξIf a low charge state (indicated by the second hand jumping at two-second intervals) is entered while a stopwatch operation is in progress, the stopwatch will reset automatically to zero.

ξIf the hand does not align with 12 o’clock, use the B button to adjust it.

ξHolding down B moves the current hand at high speed.

3.Hold down A for about three seconds, the Stopwatch 1/5-second Hand will rotate to indicate the second hand setting mode.

ξIf the hand does not align with 12 o’clock, use the B button to adjust it.

ξHolding down B moves the current hand at high speed.
