START and STOP the timer by pressing the high beam FLASH switch (2) on the left-hand handlebar switch.
When the LAP function is active, each time you press the flasher switch, the display will show the lap time for 10 seconds,
before reverting to normal mode.
You can save a maximum of 30 laps in the memory.
If the memory is full, each time you press the flasher switch, the display will not save any more lap times and will display
the flashing message "FULL" for 3 seconds until the memory is reset.
When you switch the LAP function off from the menu, the lap in progress will not be saved.
If the LAP function is active and the display is suddenly switched off (Key-Off), the LAP function is switched off
automatically (even if the timer was ON, the lap in progress is not saved).
If the lap timer is not stopped, it will roll over upon reaching 9 minutes, 59 seconds and 99 hundredths; the lap timer
starts counting from 0 (zero) and will keep running until the function is disabled.
If, however, the LAP function is switched on and the memory has not been cleared, but fewer than 30 laps have been
saved (e.g. 18 laps), the display will save any remaining laps until the memory is saturated (in this case, it will save a
further 12 laps).
This function only displays lap times once; however, lap times are saved for subsequent display in the Lap Memory
function.
