This innovative cordless telephone from AT&T operates on the powerful 5.8 GHz frequency. Its classic design provides comfort and ease of use along with advanced features, including a three-mailbox digital answering system, adjustable sound settings, the ability to run up to six handsets (one included, five optional) with only one jack, and speakerphones in both the handset and base. The dual-band (5.8 GHz/2.4 GHz) design allows the base unit to transmit with more power in the 5.8 GHz frequency band and with greater efficiency at 2.4 GHz. The phone's true duplex transmission keeps the incoming and outgoing signals from interfering with each other.
The LCDs on both the base station and the handset provide caller ID/call waiting information (provided you have a subscription to caller ID service through your local phone company). The 5840's expandability with up to five additional handsets eliminates the need to hard-wire multiple extensions throughout the home. One phone jack and one power outlet are all you need to connect the 5840 base station and handset, while each additional AT&T 5800 handset requires only a power outlet for its compact charger/cradle. Calls can be transferred from one handset to another.
The 5840's enhanced audio technology derives from advances in acoustic design that have improved the frequency response relative to conventional cordless phones. The Sound-Select feature offers four different audio settings: bass, mid, treble, and natural.
The handset receiver lights up with incoming calls and can also be set to vibrate. It stores 50 names and numbers and works with your caller ID service to remember the last 50 callers. A spare-battery charging system enables the telephone to work even in a power outage. Choose from eight ringer melodies. Use AT&T replacement battery 2401.
