LAP1 LAP2 LAP3 … …
Middle Row
In the upper row, the time since the LAP button was pressed (called laptime) is
displayed (this is the time differential between competitors when you are recording
more than one stoptime). In the middle row, the time since the START button
was pressed (called elapsed time) is displayed.
To end a session, press the STOP button (“STOP”appears in the display), and you
can see the results.
Pressing the RESET button clears all times (if "STOP" is shown in the display).
As long as have recorded the laptimes with the LAP button, you can recall them
with the RECALL button; you can also do this while another session is running.
The display with show "RECALL."
1 x RECALL = “FAST”shows the fastest laptime
2 x RECALL = “SLOW”shows the slowest laptime
3 x RECALL = “AVG”shows the average time
Pressing the MODE button escapes the RECALL function
OR
You can recall up to 99 more stored laptimes with the START button, as long as
you are in the RECALL function.
Pressing the START button toggles to a previous lap; pressing the LAP button
toggles to a following lap. NOTE: as long as "RECALL" appears in the display,

7. Stroke Rate Measurement
Select the stroke function by pressing the MODE button.
This function displays the stroke rate every minute for three cycles.
The display shows “STROKE 180.”
Press the START button, and after the third stroke (i.e. third repetition) press the
STOP button.
Now the display shows how many repetitions this would be every minute (within a
range of 11 to 180 strokes per minute).
Example: You press the START button, count 3 strokes at the rate of 1 per second,
and then press the STOP button. The display shows 60, since exactly 60 strokes per

Pressing the START button activates the pacer, which signals the strokes audibly.
The upper row of the display shows you the total time elapsed during the pacing;
the middle row shows the number of strokes/repetitions ("C"); and in the lower row
the frequency of strokes per second (“F”).
The STOP button stops the pacer.
The RESET button resets the stopped pacer.
9. Changing the Battery
.
When the display appears weak or incomplete, please take your stopwatch to a
jeweler have the battery changed. An improperly changed battery can affect the
