Philips SCD470 - Manual (Page 11)

Question Answer
The baby unit may be out of range of the parent unit or there may be
too many walls and/or ceilings between the two units. Try a different
location or reduce the distance between the two units.
The batteries may be running low. Check the batteries and replace them,
if necessary.
Why doesn’t the baby
monitor manage the
specified range of 150
metres?
The specified range of 150 metres is only valid in open air. Inside the
house the range is limited by the number and type of walls and/or
ceilings between the two units. Change the position of one or both units
to optimise the range.
What happens when
there is a mains
failure?
If you are using the units from the mains without having put batteries in
them, the connection will be lost when there is a mains failure. If there
are batteries in both units, they will automatically switch to battery
power in case of a mains failure and the connection will not be lost.
