Each model connects to the cabinet via standard two-wire twisted pair cable. The intelligent display and the extensive
spoken prompts from ESI’s Verbal User Guide deliver vital call-handling information and are readily understandable by
even a novice ESI phone user. For added reliability, each ESI phone has a sealed membrane below the keys, making it
virtually spill-proof. The sturdy base lets the user adjust each phone four different ways — from near-horizontal to near-
vertical — to fit easily on any desk or counter space.
The highly popular 48-Key Feature Phone offers an integrated standard headset jack that accepts many popular
models.

Also, headset use on any ESI phone is now easier due to the simplification of the procedure for using a
headset with the phone; i.e., it’s no longer necessary to program headset mode (on applicable desktop phones, just
program a headset key; for a Cordless Handset, just plug in the headset and the audio is switched automatically).

Note: An IVX S-Class system can have up to four 60-Key Expansion Consoles.
