While the phone can pull basic operational power from the phone line, it is highly recommended to install AA alkaline batteries in the bottom compartment. This ensures that your caller ID history, time/date, and programmed speed dial numbers are not wiped out if the phone line is disconnected. Power Adapter: Vtech Cd111a User Manual
The phone is primarily line-powered for basic calls. However, for the Caller ID display to function and maintain full brightness, you must install 3 AA alkaline batteries (sold separately). Connections: Contact VTech customer support at 1 (800) 595-9511
