IMPORTANT NOTE FOR MODEL 760M & 790M
This stopwatch can store up to 100 or 500 split/lap times depending on the model. However please note when
there are 5 free memories 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 memory even though you reset your stopwatch
and start a new event. Extra split/lap times will only be shown on the display but not recorded.
In order for the stopwatch to record the lap/split times again, you must delete the data in the DATA memory.
Please refer to the “Data Mode” section on the instruction manual for how to delete the memory.

Whenever the stopwatch stops running, the "STOP" indicator will be ON. Press the button [START/STOP] to
start the stopwatch. As it runs, the current elapsed time is shown on the lower line.
To view the current split / lap time, you can press [LAP/SPLIT].

displayed on the upper and middle line. Press [LAP/SPLIT] again, the next split/lap time will be shown and
the number of split/lap time is updated.
The stopwatch (Model 790M & 790MDEC) can store up to 500 split / lap times. The split/lap times can be
stored into the memory as you press [LAP/SPLIT] to view the current split/lap time. Meanwhile, the lap and
split time will be frozen for 5 seconds. After this 5-second period, the lap and split time will return to normal.
In addition, the fastest lap, the slowest lap, and the averages of all laps will also be recorded. As you press
[STOP] to stop the chronograph, the last lap/split time will also be stored (provided that the last lap/split time
is not the first lap/split time).
When there are 5 free memories 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 memory but will still be shown on the
display. Any fastest and slowest laps will not be stored. The memory counter will flash as the extra split/lap
times are being displayed. The icon "FULL" will be steadily ON.
The maximum memory counter value is 100 or 500.

Segmented run memory for lap/split time storage:-
A header consisting of the date/time stamp is attached to each segment to indicate the moment when you
began recording the particular timing segment. To get to this feature, press [MODE] in chronograph mode to
enter DATA mode when the stopwatch has been stopped. Records for different segments can be recalled,
read or deleted. Detailed operation in "DATA" mode is described in Data Mode section below..

Similar to the Chrono Recall mode, during speed measurement or Stop state, you can press [RECALL] to
recall the speed/lap memories. The Mode message will be shown for one to two seconds as the Mode
message display is displayed.
The Speed and Lap time will be displayed on the upper and the middle lines. The lower line shows the current
time counting. During Data recall, the fastest speed will be reviewed first, then the slowest speed and average
speed.
Further presses of [RECALL] will retrieve the memories in ascending order or reverse order depending on
whether the speed measurement is stopped or under operation respectively. During Recall, the "Recall"
indicator is ON.
(Note: Speed mode and Chrono mode will not run simultaneously. When Chrono mode is active,
Speed mode should be in reset state and vice versa.)
