The DECT2185-2 utilizes DECT technology with a frequency range of 1.9 GHz, which means you won't have to worry about this phone interfering with your Wi-Fi networks. In addition, you'll enjoy maximum voice security and the clearest voice reception, so there's no struggling to hear or be heard while talking on the phone. The DECT2185-2 includes a digital answering machine with handset access and an impressive 14-minute recording time, so you'll never miss an important message. The user friendly design of the DECT2185-2 offers menu prompts in both English and Spanish, while the blue backlit keypad makes it a snap to enter phone numbers or access features in any light setting. The large, easy-to-read LCD screen clearly displays the date, time, extension and other data and is also compatible with the caller-ID and call-waiting display. The 70 phone book locations and 30-number caller ID history help ensure that you'll never need to hunt for a number again. Enjoy the three-party conferencing option, great for talking to friends and family members. The DECT2185-2 truly adapts to your needs by being expandable to up to six handsets and by offering time-saving features. First, the high visibility message waiting indicator lets you immediately know when someone has left a message. And when you're on the phone and the call waiting beeps, you won't have to wait to find out who's calling--the LCD clearly displays the name and number of the caller in call waiting. (Note: to activate this feature, you must subscribe through your telephone company.) Use the handset as a speakerphone, transfer calls between handsets and personalize ringers so you'll know who's on the line before you pick up the phone.
