Important Note: Cordless phones such as this one require AC power to operate. When the AC power is off, you cannot dial out or receive incom- ing calls using your ET-550. To be safe, you should also have a phone that does not need AC power to oper- ate (not a cordless phone) so you can still make and receive calls if there is an AC power failure.

Your telephone operates on standard radio frequencies as allocated by the FCC. Even though the access protec- tion code prevents unauthorized use of your phone line, it is possible for other radio units operating on similar frequencies within a certain area to unintentionally intercept your conver- sations and/or cause interference. This lack of privacy can occur with any cordless phone.

We recommend you record your phone’s serial number here. The num- ber is on the bottom panel of the base.
