How do islet date and time on AT&T deft 6.0 - AT&T Office Equipment & Supplies

If your phone is similar to my AT&T DECT 6.0 cordless phone system, press Menu/Select with the phone in standby. (If your base has a corded handset, you can do this on either the base or a handset. The button is below the LCD screen on the handset. It's in the middle of the buttons below the LCD screen on my system's base.) Use the Up/Down arrow keys to navigate to Settings. (If you use the base, Up and Down are on different sides of the Menu key.) Press Menu/Select. Use the arrow keys to navigate to set date and time. Press Menu/Select. Type in the date using two digits for month, day, and year. Press Menu/Select. Today's date will be 06 21 18. Type in the time (12-hour clock) with two digits each for the hour and minutes. Use the Up/Down arrows to select AM or PM. Press Menu/Select to save. You should hear a confirmation tone. Press Exit multiple times to exit the menu system on the base. Press Off from a handset.

I hope this helps. Please add a comment with your phone system's model number if you'd like me to search for a manual. The manual for a system like mine, the CL84215, is here: https://cdn-media-att.vtp-media.com/products/CL/CL8XXX5/CL84XX5_CIB_i4.0_20170412.pdf .
