This has to be done on Ext 101, or whichever phone is the programming phone. Press program *#1234. Then enter in 004. Press Speakerphone. It should be asking for a jack number. You can press speakerphone again to go to the first ext. Spell out the name using the keypad (2 is A, B and C and so on). When done press the autodial/store button. Then you can press speakerphone to go to the next phone. To get out of programming just pick up and hang up your phone or press the program button.

Set the phone on the charging cradle and press the ON button while phone is in crade. You may need to use the speakerphone button to do this. Turning the phone on while in the charging cradle will resync your handset with its base. Try it! It should work!

It's automatic. Press the SP Phone button.

My headset is a TCA-60 and it works in all systems on all Panasonic phones.

Well, I found the solution. I traded batteries from one the working handset to the non-working one, and the problem was corrected. Thus I need a new battery.
