The Panasonic KX-TG4000B telephone comes with a base unit, base handset, cordless handset, charger, two AC adapters, 4-wire telephone line cord, handset cord, belt clip, warranty card, and user’s manual. This complete telephone system gives small businesses the advanced features of a business phone network, without expensive installation and wiring. To set up the system, hook up the base to your phone line and plug it into an outlet, then put the handset in the desired location and plug in the recharging stand. The 4-line, multi-handset system can accommodate up to eight cordless handsets with one phone jack. The handset’s integrated battery offers up to eight hours of talk time and up to 96 hours of standby life. The system employs 2.4 GHz frequency-hopping spread spectrum technology, a digital technology that promotes long range and crystal clear clarity. The technology "hops" constantly through a range of available channels to reduce interference and to provide improved security against eavesdropping. The all-digital auto attendant answering system automatically answers all incoming calls with a recorded greeting, or it can be programmed to route callers to a desired extension or mailbox. There are four separate voice paths, so four system users have access to the messages at one time. There is a general delivery mailbox on the base unit, plus one individual mailbox for each additional handset that is added to the system. Caller ID/Call Waiting and/or voicemail service can be provided by your telephone service provider with a subscription. The voicemail system provides up to 100 minutes of recording time and contains features such as a pre-recorded outgoing message, remote operation, Tollsaver, and skip-and-repeat. Messages are stored in flash memory, so they’re not lost during power failures or interruptions. Caller ID stores up to 100 names on the base unit or up to 30 names on each handset with direct callback capability. With the pager call function, you can program the phone to notify your pager when you receive an incoming call, and you can also forward caller ID data to your pager’s display. You can program the handsets, which have a digital duplex speakerphone, with an eight-step volume control, to answer calls when any key is pressed on the keypad. The Power Fail Operation feature assures that the base unit will transmit calls during a power outage for a limited time. Other features include a two-way intercom, a headset jack in the handset, and a lighted handset keypad. There is a last 10 number redial, low battery indicator, out of range indicator, flash button, and pause. Accessories such as cordless telephone batteries, AC adapters, handset chargers, headsets, and wall mounting adapters are available. Panasonic offers product support and technical assistance through the Panasonic community or via live chat as well as by email or phone. Add this phone system to your office or small business and you will never miss a call again nor will you suffer from downtime or low quality calls.
