ESI Feature Phone operation
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 Digital Feature Phone vary from those on the 12-Key Digital Feature
Phone. The 12-Key Digital Feature Phone's programmable feature keys can be set for certain optional
features (described on page F.7) that come as fixed-feature keys on the 24-Key Digital Feature Phone.
Keys' LEDs (lamps)
The LEDs (light-emitting diodes), or lamps, 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.
• Red indicates an occurrence at another station.
• A solidly lit lamp indicates in-use status.
• Blinking indicates an action, such as ringing or holding, is required; a fast blink calls for
immediate action.
As an example, a blinking red key is a call ringing at another station; blinking green signifies ringing at
your station. (See also "Line keys," page F.6.)
SPEAKER key and speakerphone operation
For hands-free conversation, use the SPEAKER key. When an outside call rings, you can press
SPEAKER to connect to the caller via your phone's built-in speakerphone. This lights the SPEAKER
key's LED. Or, while using the handset, you can switch a call to the speakerphone by pressing
SPEAKER and hanging up the handset. (To revert to the handset from speakerphone mode, lift the
handset again.) To perform group listening — i.e., 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 to enable or disable hands-free answer — press 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; outside calls ring with a double-ring cadence.
Note: The 12-Key Digital Feature Phone only supports hands-free listening. You must pick up the handset to
respond to the caller.
Volume/scroll keys
The two smaller keys just above the dial pad 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, such as special characters: #,
E.2
, P, and F.
