E.1
ESI Feature Phone operation
Display
When your phone (or station) is not in use, the display will show the current date and time, activated
features such as DND (do not disturb; see “MUTE/DND,” page E.3), monitor mode, and — on a 48 or
24 –Key Digital Feature Phone — the system’s current line usage. A 12-Key Digital Feature Phone
does not display line usage.
Note: An ESI Cordless Handset’s display is similar to that of the 24-Key Feature Phone; one difference is that
a Cordless Handset doesn’t show line usage.
Each block on the bottom line of the
display will represent an individual line
(as in the examples, right). Incoming
calls usually are assigned beginning
with Line 1 at the far-left line indicator.
Outgoing calls are assigned from the
highest numbered line beginning at the
far right.
As you use your ESI Feature Phone, its display changes frequently to give you detailed information
during call processing and voice mail operations.
Caller ID
If you subscribe to Caller ID from your telephone service provider, the phone’s display will show an
outside caller’s name and/or number.

In some instances, the service provider can send only a general
caller status — such as UNAVAILABLE, PRIVATE or NO DATA SENT.
Keys
Programmable feature keys
The programmable feature keys at the top of the Digital Feature Phone — 30 on a 48-Key, 12 on the
24-Key, and nine on the 12-Key — have been pre-programmed by the installer. You may wish to add to
or change some of these keys to perform different functions explained throughout this manual. Press
PROGRAM to verify current settings (see page C.1).
Important: Each of the two smaller Feature Phones, 12-Key and 24-Key, has a combination (“combo”)
PROG/HELP key, while the 48-Key Feature Phone has separate PROGRAM and HELP keys. If
you’re using a 12-Key or 24-Key Feature Phone, press PROG/HELP wherever this User’s Guide
instructs you to press either PROGRAM or HELP.
Each ESI Cordless Handset has a combination TRANS/CONF/PRG key that you should press
when this User’s Guide instructs you to press PROGRAM.
2
Note: To use voice mail, conference calling and mute/DND on a 12-Key Feature Phone, or to use call
recording or do-not-disturb mode on an ESI Cordless Handset, you must program these features into
programmable feature keys (see “Optional features,” page F.12).
1
If you don’t subscribe to Caller ID, the LCD will show which line is receiving the call, instead of the caller’s name or number.
2
Each Cordless Handset has no access to the system’s Verbal User Guide (“help mode”) and, therefore, no HELP key.
