Note:

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.

1.-

On any ESI phone within the system, press PROG/HELP.
Note:If using an ESI Feature Phone that has separate PROGRAM and HELP keys, press PROGRAM.

2.-

The normal station programming menu prompt will begin to play.

3.-

Stop the prompt by pressing HOLD (or, on an older ESI phone, PARK).

4.-

Enter the Administrator password and then press #.
Note: If this doesn't admit you to Administrator-level programming (the phone display should show ADMINISTRATOR), contact your ESI Reseller for assistance.

5.-

Access Function 14 by pressing 1 4.
(If the system prompts you to press 1 to set time and date, do so.)

6.-

Enter a new time using a twelve-hour format and then press #.
For Example: 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).

7.-

Select AM or PM by pressing a scroll key and then #.

8.-

When the date appears, either:
Press # to accept the currently displayed date as correct;
or
Enter a new date in an eight-digit format, including leading zeroes, and then press # and hang up to finish the entry.
Example:
For October 18, 2007, enter 1 0 1 8 2 0 0 7 # (and, to repeat, leading zeroes are required here, unlike in Step 5).

Automatic adjustment for Daylight Saving Time

Notes:
This does apply to ESI phone systems manufactured before February, 2003; specifically, IP 200, IP 40, IVX 128 Plus, IVX 128, IVX 20 Plus, IVX 20, and [original] IVX. If you don't know which phone system you have, consult your ESI Reseller.

This feature, when enabled, causes the phone system's real-time clock to adjust itself automatically for Daylight Saving Time. The options are AUTO [enabled] and DISABLE (the latter is best for counties or states that don't observe DST).
To set this feature

1.-

On any ESI phone within the system, press PROG/HELP
Note:
If using an ESI Feature Phone that has separate PROGRAM and HELP keys, press PROGRAM.

2.-

The normal station programming menu prompt will begin to play

3.-

Stop the prompt by pressing HOLD (or, on an older ESI phone, PARK).

4.-

Enter the Administrator password and then press #.
Note:
If this doesn't admit you to Administrator-level programming (the phone display should show ADMINISTRATOR), contact your ESI Reseller for assistance.

5.-

Access Function 142 by pressing 1 4 2 and then #.

6.-

The phone display will show AUTO TIME SET, and either ENABLED or DISABLED. If necessary, use the phone's scroll keys to toggle between the two settings. We recommend the ENABLED setting. When the display shows the setting you want, press #.

7.-

The phone display will now show DAYLIGHT SAVING, and either AUTO or DISABLED. If necessary, use the phone's scroll keys to toggle between the two settings. If you want your phone system to adjust its clock setting automatically whenever your time changes between Daylight Saving Time and Standard Time (either direction), select AUTO. If you live in an area which doesn't observe Daylight Saving Time, select DISABLED. When the display shows the setting you want, press # # and hang up.
