A:AnswerThe transmitter that is left with the baby is powered only by a AC wall plug in. The two monitors have rechargeable batteries so it is really convenient to have them set up in any particular room that you are in charging and then when you need to leave the room both monitors have a clip so you can carry the monitors with you wirelessly.
A:AnswerI had my doubts at first. We are seniors and wanted it in case of an emergency I could hear my husband call out for me at night. I love it, works great no problems at all.
A:AnswerHi - 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.

A:AnswerHi - No, there will be no interference as long as the VTech DM221 are installed on separate rooms and are far away from each other. We also recommend that you place the baby monitors away from laptops, smartphones, microwave or WiFi streaming devices. Thank you for your interest! ~VTech Support
A:AnswerLula - The VTech DM221-2 is designed for use in North America only, this requires 110-120 V AC power. Thank you for your interest! ~VTech Support
A:AnswerJenn - We are sorry but the VTech DM221 is a non-expandable audio monitor. We have the DM221-2 if you are looking for audio monitors with two cameras. Thank you for your interest! ~VTech Support
A:AnswerMonitor 4 rooms, or monitor FROM 4 different rooms.
I THINK 2 sets could monitor one "parent monitor" FROM 4 different rooms. I do not think they would monitor 4 rooms. I also don't know whether or not you can use 2 parental monitors in the same system--- don't think so, but not sure
A:AnswerHi - The replacement battery for the VTech DM221 is the BT266342. You can check if there is one available locally. To ensure that you get the right one, bring the battery with you. Otherwise, you may check our website.
