Liquid crystal display (LCD)
When your phone (or station) is not in use, the liquid crystal display (LCD) will show the current date and time, activated features such as DND (do not disturb), monitor mode, etc.) and the system’s current line usage.
If your system has 16 or fewer lines, each block on the bottom line of the display will represent an individual line (as in the seven-line example, below). 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.

If your system has 17 or more lines, then the bottom line of the display will provide a graphical representation of relative line usage (see below). The ratio of bars on the left and right will indicate the relative amount of incoming and outgoing lines in use. The relative size of the blank area in the center will indicate lines not in use.


As you use your ESI Feature Phone, its display changes frequently to provide 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.

Programmable feature keys
The 16 programmable feature keys at the top of the phone 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 0 3 and any key to verify the current settings (see “User programming: an introduction”).

Fixed-feature keys
The fixed-feature keys on the phone are permanently labeled as to their usage. The PROG/HELP and MUTE/DND keys have two purposes each; however, the IVX phone system will govern this by permitting only the appropriate function when either is pressed, depending on the circumstances at that moment.

LED lamps
The LEDs (light-emitting diodes) associated with the programmable and fixed keys aid in determining the status of their function. In general, green indicates a function associated with your phone, while red indicates an occurrence at another station. A solid lamp indicates in use, blinking means an action (such as ringing or holding) is required, and a fast blink means immediate action. As an example, a blinking red key is a call ringing at another station; blinking green signifies ringing at your station.

Help mode
Your ESI Feature Phone’s Help mode — a carefully conceived combination of spoken information, display readouts and even key illumination when appropriate — is a powerful tool to help you learn how to use the system’s many features.
Tutorial
When your station is idle, press PROG/HELP and then follow the spoken Help menu to:
- Learn how to use the phone
- Hear a description of how any key is used
- Learn how to use voice mail features
- Hear a complete tutorial on phone operation
Help during station programming
Press PROG/HELP while programming a function to hear a detailed description of the function.
Help during a call
Press PROG/HELP while on a call and this will place the call on hold, whereupon you can use Help mode to hear a description of the function you wish to perform. When you exit Help mode, you will be reconnected to the call.
While you are either in Help mode or programming your phone, your station will be temporarily placed in DND (see “MUTE/DND”). Anyone calling your station while you are in DND will be forwarded to your mailbox (or other destination set by the installer).
Exiting Help mode
To exit Help Mode, simply hang up.

Dial tone
When you first lift your handset, you will hear an internal dial tone that allows you to call other stations or perform other internal functions. To gain an outside dial tone, dial 9 (or 8 or 71–76)* or press a programmable feature key that has been set as a line key. (A line key, when pressed, automatically gains an outside line. Consult your system’s administrator if you have questions.)

SPEAKER
For hands-free conversation, use the SPEAKER key.
If you press SPEAKER when an outside call rings, this will connect you to the caller via your phone’s built-in speakerphone and light the SPEAKER LED (light-emitting diode).
While using the handset, pressing SPEAKER and hanging up the handset will switch the caller to your speaker. To revert to the handset from speakerphone mode, lift the handset again.
Group listening
To have a handset conversation along with the caller’s voice broadcast over your speaker, press SPEAKER while on a handset conversation but do not hang up the handset.

Hands-free answer (internal calls only)
You can program your phone either to enable or disable hands-free answer (PROG/HELP 3 5).
With hands-free enabled, an internal call to your station generates a short ring and a double connect tone, then automatically connects the caller to your speakerphone.
With hands-free disabled, an internal call to your station generates a single-ring cadence.
Note:
Outside calls ring with a double-ring cadence.

Volume/scroll keys
The two smaller keys just above the dialpad labeled
and
serve two purposes:
- Adjusting the volume heard through the handset and speaker — Your phone will maintain the chosen volume setting until you change it.
- Serving as scroll keys for operations, such as Esi-Dex or programming, that may show several entries on the display.

MUTE/DND
Mute
To disable your handset or speaker microphone during a conversation (either
with the handset or speaker), press MUTE/DND. While the
mute function is activated, the MUTE/DND LED will blink
rapidly and MUTED appears on the display.
DND
When your phone is idle and you wish to make sure its calls
go straight to voice mail, press MUTE/DND to toggle your
phone in or out of do-not-disturb mode. The display will show
DND and the MUTE/DND LED will glow amber.
| Note: | If you press MUTE/DND while your phone is ringing, this forwards the call to your voice mailbox (see “Voice mail operation”) and your station will be placed in DND. |
