• Pressing P1 stops the chronograph (display on the upper screen:
CHR ADD
alter-
nating with the 1/100
th
of a second).
• Pressing again on P1 restarts the chronograph.
• A long press on P2 will reset the chronograph to zero as well as all the interme-
diate times (

If one forgets to turn the timing off, when the total time reaches 99 hours, 59
minutes and 59 seconds, measuring ceases and the upper screen displays

c) Flyback
At any time, a long press on P1 will restart timing from 0 (when the pushpiece is
released): this is the
FLyBACK
function. The seconds hand positions itself directly on
the active timing second. The
FLyBACK
function results in the loss of all intermediate
times that have already been recorded.
d) Tachymeter
When the chronograph has been stopped after a measured time without an inter-
mediate time, a short press on P2 will display the average speed corresponding
to the total time measured – for a pre-introduced distance (see chapter 10.f). The
upper screen displays
SPEED
, and then the speed unit; the lower screen shows the
value of the speed. The display of the speed lasts about 5 seconds and then reverts
to the preceding display.

CHR ADD

• A long press on P2 will put it back to zero.

• Pressing P1 starts the chronograph. The upper screen displays
CHR RUN

xx
alternating the 1/100 th of a second; the timing continues in the background. The
time remains flashing for ten seconds after which the display switches to the
total time being recorded.
• Repeat again for xx intermediate times (
SPLIT
xx) up to a maximum of 50 times.
