CLEARING ALARMS
To clear an individual alarm, press Acknowledge after the relevant
alarm. To clear all the alarms, press Acknowledge All button (top right).
If the alarm cannot be cleared, it will reappear on the display and the
underlying cause for this must be resolved before the alarm can be

(before the alarm is due) the filter alarm can be reset under the Set-
tings menu. See page 22, fig. 3.
