Why does the parent unit react too quickly to other sounds than my baby makes?
The baby unit also picks up other sounds than those of your baby. Move the baby unit closer to the baby (but observe the minimum distance of 1 meter/ 3.5 feet).
The sensitivity level may be set too high. When your baby makes soft sounds, the sensitivity has to be higher. However, the louder your baby sounds, the lower the sensitivity level can be set. You can change the sensitivity of your baby monitor on the parent unit's menu.
