** The AVERAGE calculation and BEST record do not take into account the last
section of time before STOP. Therefore, in order for the stopwatch to keep track of
the average and best records of all Laps, always use the B button until the end of
the race. Pressing D again will go to the next race records or return to the 1st
race records (if there is no further race).
In the CHRONO MODE before the start of a race, such as in Fig.7, push and hold B
for 2 seconds will go to the SPEED SET mode as is shown in Fig.14. The first digit in
the lowest row is flashing to indicate setting of the thousandth digit of distance. Push
A to set and B to select the next digits. The highest setting for distance is 9999.999.
After the digits are set press B again to set the TIME unit with the top left corner HR
flashing. Use A to set to HR (for /hour), MIN (for /minute) or SEC (for /second).
When the distance and time unit are set, press C button to return to the SPEED
MODE (Fig. 15). (Pushing C button anytime during the setting will return to the
SPEED mode).
