The principal settings of the clock are stored in flash memory – your
preferred configuration is stored even after powering off the clock. To
access the configuration mode press and hold the ‘Set’ button. After 2

For each parameter, and referring to the table below, scroll through the
range of possible values by pressing the ‘Up’ button. When the desired
value has been reached, move on to the next parameter by pressing the
‘Set’ button. When the last parameter has been set, pressing ‘Set’ one
more time will revert the clock back to time display mode.
