The Panasonic KX-TG2720S offers 2.4 GHz frequency-hopping spread spectrum (FHSS) technology for clear sound, longer range, and improved privacy. Use multiple handsets without worry of cross-talk or eavesdropping, because the FHSS technology randomly changes frequencies several times per second. Plus, an advanced microchip answering system records up to 15 minutes of messages and makes retrieval easy. A voice synthesizer prompts callers through the messaging system and identifies each incoming message with the time and day it was received. This model can handle eight cordless handset stations. You can add up to seven additional handsets anywhere in the house while using only one base unit and one phone jack. This eliminates the need to rewire your phone line to other parts of the house. With privacy mode, you can block all other handsets from joining the conversation. This feature automatically shuts off when the call is completed. Or, conference one outside line on up to four handsets simultaneously. Share the names and phone numbers programmed in one handset with any other handset in the system.
Other features include a toll saver that allows you to check your messages away from home and avoid toll charges. Use the intercom function to listen to what's going on in any room that has a handset. Use the four-line LCD to view call status, programming options, directory items, and, if you subscribe, up to three lines of caller ID information, so there's no need for scrolling. Backlighting greatly aids visibility in low-light areas. The system records messages in flash memory so they're unaffected by power failures or interruptions. Personalize your ring tone to alert you to incoming calls.
