Question about AT&T E5813B Trio Cordless Phone
SOURCE: how do I change the date
Changing the date on a Partner system is done on either ext 10 or 11. At one of those ext's press the feature key and "00"
next press the left hand intercom twice
the display should say system programming
enter in "#101"
the display should say system date and the current programmed date
enter the new date in mmddyy format
press feature "00" to logout

The display will blink if power is cut either by unplugging or if the control system is power-cycled. The cause of the power glitches needs to be located & corrected. Changing the ring tone/cadence depends on which control unit is being used.
