The following is derived from the explanation of Function 14 in your ESI phone system’s Installation Manual or Administrator’s Manual (as the case may be).

Current ESI phone systems can be configured to reset the time automatically when Daylight Saving Time (DST) ends or begins each year. However, if your system is not configured that way (or it’s an older ESI phone system that doesn’t perform the automatic time change), the following instructions explain how to reset the time and date manually.


To configure a compatible ESI system to change time automatically when Daylight Saving Time ends or begins, see “Automatic adjustment for Daylight Saving Time,” below.

On any ESI phone within the system, press PROG/HELP.

If using an ESI Feature Phone that has separate PROGRAM and HELP keys, press PROGRAM.

The normal station programming menu prompt will begin to play.
Stop the prompt by pressing HOLD (or, on an older ESI phone, PARK).
Enter the Administrator password and then press #.

If this doesn’t admit you to Administrator-level programming (the phone display should show ADMINISTRATOR), contact your ESI Reseller for assistance.

Access Function 14 by pressing 1 4.
(If the system prompts you to press 1 to set time and date, do so.)
Enter a new time using a twelve-hour format and then press #.

Enter 1 2 3 3 # for 12:33 or 3 1 5 # for 3:15 (note that you need no leading zero for the time).

Select AM or PM by pressing a scroll key and then #.
When the date appears, either:
Press # to accept the currently displayed date as correct;
Enter a new date in an eight-digit format, including leading zeroes, and then press # and hang up to finish the entry.

For January 16, 2009, enter 0 1 1 6 2 0 0 9 # (and, to repeat, leading zeroes are required here, unlike in Step 5).
