Battery backup
In the event of a power cut, the built-in lithium battery
will keep your time and programme settings for up to 15
days.
After 15 days without mains power the unit will switch off
and two dots will show in the display. However all your
programmed on/off times will be remembered.
When the mains power is restored, the unit will need to
be reactivated by pressing the
PROGRAMME
button,
and the time and day will need to be set (see page 13).
