First to change the clock to a 12 hour instead of a 24 hour requires a bit of CAUTION. You have to go into the technician level of programming so be careful. From a display phone, Press #, ( Programming ) is displayed, enter 20, ( MMC Disabled ) is displayed, enter password ( 1 2 3 4 is default ), enter function 4 for 12 hour clock, enter # to exit. If the time and date are displayed wrong you have to go to # 55 and reset time and date.
YY MM DD W HH MM format. W = Day of week with 1=Monday and HH MM must be entered in Military time even though you have a 12 hour clock set. Good Luck
