NOTE:
The programme required will probably stay constant every time you race at the same club, and will
probably only need changing if you race somewhere else that uses a different starting sequence.
SILENCING THE ALARM

the alarm. This is done by pressing 'MODE' and holding it down for approximately 2
seconds. A short bip indicates that this has been successful, and the icon of the bell in
the top right of the display disappears to show the alarm is off. To re-activate the
alarm press and hold 'MODE' for 2 seconds until you hear the bip and the icon of the
bell comes on to show that the alarm is on.

whether you want just one period of that programme (by pressing 'PROG' just once for countdown repeat)
or multiples of that period if required (by pressing 'PROG' several times for countdown and up or the 1
minute programme of countdown repeat).

holding this in, press the 'CLEAR' button. You will see the icon
