  • Page 2 43-1048.fm Page 2 Tuesday, August 17, 1999 12:45 PM FEATURES Your RadioShack ET-548 25-Channel Cordless Headset Telephone gives you communication with both portability and convenience. It comes in two parts, a headset and a base. The phone’s headset connects to a cord- less remote keypad, so you can make calls away from its base.
  • Page 3 When the AC power is off, you cannot dial out or receive incoming calls using your ET-548. To be safe, you should also have a phone that does not need AC power to operate (not a cordless phone) so you can still make and receive calls if there is an AC power failure.
