Edge E Expansion Module

The Poly Edge E Expansion Module (85W93AA) adds a dedicated bank of line controls to a compatible Poly Edge desk phone, helping organize frequently used call functions in one place.

It provides three pages of 22 multifunction keys, for 66 keys altogether. The illuminated dual-color keys can be configured for line registrations, call appearances, speed dials, direct stations or busy lamps. A 5-inch color LCD (480 × 800 pixels) displays the module’s pages.

The module supports one unit on Poly Edge E400 and E450 phones, or up to two on E500 and E550 phones. Setup is plug and play, and the host phone supplies its power.
