Follow the user manual for a better understanding of use.
This configuration includes one parent unit (monitor) and one baby unit (audio monitor)
DECT 6.0 provides crystal clear transmission, eliminating the annoying white noise you hear from analog monitors
5-level sound indicator - graphic bars on the parent unit indicate the level of sound in your baby's room so you can visually monitor the noise level with the unit muted
Sometimes all your baby needs is to hear the sound of your voice - comfort your infant with the 2-way talk-back intercom
Rechargeable batteries provide the parent unit with up to 18 hours of monitoring time on a single charge, or use two AAA batteries (not included)
