Philips Avent SCD525 - Manual (Page 23)

Question Answer
The microphone sensitivity level of the baby unit may be set too high,
which causes the parent unit to consume a lot of energy. Decrease the
microphone sensitivity level in the menu of the parent unit.
Why doesn’t the
battery symbol appear
on the display of the
parent unit when I start
to recharge the parent
unit?
It may take a few minutes before the battery symbol appears on the
display of the parent unit when you charge the parent for the first time
or after a long period of non-use.
