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 14).
