seconds. The maximum display of speed is 9999.999, if any calculated
speed is over this value, Error will show in the middle row and speed value
will not be stored into memory.

average speed/lap and then each speed/lap stored in memory.

ii.

When the stopwatch is running; the same is displayed except that the
time continues to run on the bottom row.

Stroke/Frequency Measuring Mode
This mode calculates frequency by taking 3 strokes (cycles) within a time period
and then calculating the expected number of cycles if that action is continued for
1 minute.
1.

Press MODE button to show the Stroke /Frequency Measuring Display.

Start the measurement by pressing the START/ STOP button. Then press

Pressing the START/STOP button longer than 18 seconds will cause an
Error to display which indicates the time period is too long.

Pressing the RESET button while the measurement is stopped or while an
Error is shown, causes the digits to be reset to 2400.

ALL OPERATIONAL DIFFICULTIES
If this unit does not function properly for any reason, replace the battery with a
