Sound sensitivity and sound activation
When VOX is selected, the parent unit screen stays off to save power when the baby unit detects
sounds that are lower than the set sensitivity level. Once the baby unit detects sounds that are
louder than the set sensitivity level, the parent unit screen turns on automatically. It will then turn
off again after 50 seconds if the sounds detected are lower than the set sensitivity level.
Adjust the sound sensitivity of the
baby unit
The parent unit screen will turn on only when the
detected sounds exceed a set level.
Use the parent unit to adjust the microphone
sensitivity of your baby unit. The higher the
sensitivity level, the more sensitive the baby unit is
in detecting sounds that transmit to the parent unit.
The VOX sensitivity level is preset to the highest
level.
