Philips AVENT Écoute-bébé vidéo numérique - Manual (Page 10)

Do not position the baby unit with the microphone facing downwards. When the microphone
is blocked by the base, the baby unit does not pick up sounds properly.
4 Place the parent unit within the operating range of the baby unit. Make sure it is at least 1
metre/3 feet away from the baby unit to avoid acoustic feedback (Fig. 21).
For more information on the operating range, see section ‘Operating range’ below.

video display. (Fig. 22)
Note: If the brightness is set to a high level, the parent unit consumes more power.
Sound level lights
The parent unit continuously monitors the sound level in your baby’s room and the sound level
lights let you know if there is any activity. If your baby cries, the green sound level lights light up on
the parent unit.
- As long as the baby unit does not detect a sound, all sound level lights on the parent unit are
out.
- When the baby unit picks up a sound, one or more sound level lights on the parent unit go on.
The number of lights that go on is related to the loudness of the sound picked up by the baby
unit. The sound level lights also go on when the parent unit is set to a low volume or when the
automatic screen activation mode is activated (see section ‘Automatic screen activation’
below) (Fig. 23).
