I just bought 4 of these monitors. When I opened the package, the date on the back of the monitor said July 2022. Doesn't that mean it's expired?

Thank you for your question, Tina. The date on the back of the unit is the date of manufacture, not the expiration date. This unit comes with a 7yr warranty from the date of purchase. If you have any additional questions or concerns, please don't hesitate to reach out to us directly at First Alert Customer Support at 1 (800)-323-9005.
