This two-line 2.4GHz digital spread spectrum system comes with one handset and can be expanded up to seven additional handsets without extra phone jacks. A microchip handles all messages in the digital answering system. With no tapes to fuss with, operation is simple, efficient and virtually silent. See the name and phone number of incoming calls from the LCD display on either the base or the handset, even while talking on another call. Dual digital duplex speakerphones (base and handset) reduce echo and dropout. The Caller ID? three-line LCD display shows each caller's complete information without additional scrolling. Backlighting on the handset LCD greatly aids visibility, especially in low light. Also included is intercom between the handsets and/or the base, five-way conferencing capability, dual keypads and six selectable ring tones. Additional handsets require the KX-TG2740 Base Station for operation, which has one- or two-line capability.
