Sound activated screen and audio
When Sound activation is on, the parent unit screen stays off to save power when the
baby unit detects no sound.
Once the baby unit detects sounds that are louder than the chosen sound sensitivity
level, the parent unit screen and speaker turn on automatically. The parent unit will then
turn off again after 50 seconds of no sound detection.
Note:
• If you have muted the parent unit speaker, only the parent unit screen will turn on
when a sound is detected.
