Five new speakerphones.
Two new DSS/BLF consoles.
Four new circuit modules.
Two upgraded control units.

With a Panasonic digital phone system, you can now use 16 different multi-line phones and four DSS/BLF panels -- more choices than any other brand.

• You can have display phones that show one, two, three, or six lines of text.
• New phones have either 12 or 24 programmable "soft key" buttons, that can be used to select outside lines, and to provide one-touch intercom calls, and one-touch speed-dial calls, and to activate features such as paging,  background music, call recording, and transfer to voicemail.
• Phone with six-line display has 24 programmable buttons, compared to 12 buttons on older model.
• All new phones will work with KX-TD308, TD816, TD1232, TD500 control units. They will not work with analog control units.
• Full operation of the new phones' features requires a firmware chipset upgrade or a new "dash-three" control unit. Some control units also need a new CPU.
• New 12-button KX-T7320 and 7431 may not work properly with first generation KX-TD308 control unit. 
• New KX-T7436 phone with big display shows 8 screens of features -- a bit more than 7235. You can use the Jog-Dial to scroll from the bottom of one screen to the top of the next.
• The Jog-Dial controls volume, ringing and the display.
• It's very convenient for quick scanning through personal and system speed-dialing directories, feature access list, programming steps.
• While scanning, when you come to the entry you want, just tap a button to activate the feature or make the call.
• Volume control function maintains settings for ringer, speaker, handset, and even headset.
• Select from 8 ringing sounds for intercom calls. We don't know if the door intercom sound can be changed.
• Phone-users can disable paging announcements at their phones.
• Off-Hook monitor feature allows people near a phone to listen to a conversation through its speaker, while one person uses handset -- like old ComKey 416 phones.
• System speed-dialing directory can hold 500 names and numbers, compared to 100 in earlier systems.
• Number of account codes increases from 20 to 128
• Caller ID name-number table increases from 250 to 500 entries.

• Whisper Off-Hook Call-Announce provides quiet announcement through handset to someone on a phone call. Other party does not hear announcement. There is no handsfree response to whisper announcements.
• New phones are about half-inch wider than older phones.
• New phones have handset mute -- long overdue.
• System programming now covers installation of additional types of expansion modules.
• Older KX-T7200-series phones will gradually be discontinued. New stock will disappear quickly, but refurbished phones should be available for years to come.
