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.2) and monitor mode, and — on a 24–Key
Feature Phone — the system’s current line usage. A 12-Key Feature Phone does not display line usage.
Each block on the bottom line of the display will represent an individual
line (as in the example, 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 Feature Phone — 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 PROG/HELP to verify current
settings (see page C.1).
Note: Key codes for VOICE MAIL, CONFERENCE, and MUTE/DND for a 12-Key Feature Phone must be
programmed on a programmable feature key to use these functions. See page F.6.
Fixed-feature keys
The fixed-feature keys on the phone are permanently labeled as to their usage. The FLASH/RDL and
MUTE/DND keys both have dual purposes; your ESI phone system will govern this by permitting only
the appropriate function when either is pressed, depending on the circumstances at that moment. The
different phone models have some different fixed-feature keys.
Note: The fixed keys on the 24-Key Feature Phone vary from those on the 12-Key Feature Phone. The 12-
Key Feature Phone’s programmable feature keys can be set for certain optional features (described on
page F.6) that come as fixed-feature keys on the 24-Key Feature Phone.

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.
