Keypad problems with your KX-TGA400b?

The KX-TGA400B handset works with the KX-TG4000B four-line cordless telephone system, giving your small business or home the productivity-enhancing features of a business telephone system without the high price tag. It communicates with the KX-TG4000B base unit in both directions using 2.4 GHz frequency-hopping spread spectrum (FHSS) transmission. FHSS technology improves calling range and clarity, and eliminates crosstalk. Because it rapidly changes transmission frequencies within the 2.4 GHz bandwidth, this cordless system helps reduce the possibility of eavesdropping.
The KX-TG4000B phone system operates via cordless transmissions, so no expensive (and messy) wiring or installation is required. Simply hook up the base to your phone lines and plug it into an AC outlet. Then, set up the included KX-TGA400B handset in the desired location and plug in the recharging stand. You can add up to eight KX-TGA400B handsets to the system.

Dual caller ID with call waiting lets you view the name and number of all incoming callers on either the base unit or handset LCD--even if you're already on the line. This caller ID feature also stores up to 50 names on the base unit (up to 30 names on each handset), with direct callback capability. And thanks to caller ID pager call, you can even program the phone to notify your pager when you've received an incoming call, and to forward caller ID data to your pager's display. (Subscription to caller ID services is required.)

Other handset features include two-way intercom/paging with the base unit and other handsets, alighted handset keypad, headset jack, and a belt clip. The handset offers up to eight hours of talk time and up to 96 hours of standby battery life.
