Place the watch so that the transfer terminal is
touching the centre pin of the communication unit’s
three way connector. (Look at the picture below)
P.How to perform all reset
When the battery is changed or the watch is not
functioning or displaying normally, perform the “all
reset”.
1. Press all 4 buttons at the same time for more
than 2 seconds then release them.
– All possible display segments will appear.
2. Press either one of the buttons and release.
– At that time, an alarm will ring confirming that all
functions were reset.
After the alarm, the LED will flash 3 times. The
watch will display the calendar mode in which
“1 Jan / Mon / AM 12:00” will appear.
★Caution: when resetting all functions.
• If you perform the “all reset”, all log and profile
data will be deleted, so transfer all data to a
personal computer or record it in a log book
beforehand.
• When you release all 4 buttons, if the water sensor
is wet, “CHEK” (D201/D207) / “TIME” (D202/D208)
will appear in the dot display. After that, all possible
display segments will be black. Please operate the
watch in the same way as normal resetting.
