You have to change from extension 101. Once you are on extension 101 then you need to press program then 0. enter date backwards ie(081104) then day (1=mon 2=tues 3=wed 4=thur 5=fri ect.) then enter time ie(0300 for 3:00) then 0 for am or 1 for pm. so it would go like this
Press program then 0
Enter (example for Tues. Nov. 11,2008 3:00 pm) would be
081104 2 0300 1
then press store then program again and it's set.

From the phone connected to Jack 01 (usually 101) press PROGRAM *#1234 and dial 000 and the SP PHONE button. Your display should show a blinking cursor over the year. Use the FWD and CONF buttons to go forward (and back) and the AUTO ANS or keypad to change the entries. Finish by pressing STORE

If you are using the KX-T7730 phone with a Panasonic KX-Txx 308/616/824 system. From the Switcboard / Main telephone ( ext 101, 10 or 9 ) with the handset on the cradle press Program * # followed by the system password ( default is 1234). Now press 000 and then Sp-Phone.Enter the year and then scroll to the month with the right scroll key (located at the right bottom corner of the phone). To change the month use the AUTO ANS / MUTE button. Now scroll right again and change the date and day. To change the day again use the AUTO ANS / MUTE button. Now scroll right again and the time will appear. Set the time. To change am/pm scroll to it and again use the AUTO ANS / MUTE button. Press Program to exit program mode and you are done.
