A:Answer Hi - The VTech DM221-2 has a talkback feature. If someone is using the other parent unit to talk to the baby, the voice will also be broadcasted to the other parent unit. During this period, no sound will
transmit from the baby unit to any parent unit. For more details, please contact our Consumer Sales and Service Center between the hours of 9:00 AM and 3:00 PM Monday through Friday at 1-800-595-9511.
Thank you,
