What if the secondary screen or expansion module isn't working on my Poly Edge E400?

What You Are Experiencing
The secondary screen on the right side of the E400 is blank, showing incorrect line assignments, or the optional Expansion Module is not displaying contacts or lines correctly.

Secondary Screen Overview
The Poly Edge E400 has a built-in secondary screen (item 16) on the right side of the phone with its own line keys (item 17) and pagination keys (item 18). This supports up to 12 additional lines beyond the main display's 32 lines.

Secondary Screen Is Blank or Dark

  1. Press the Secondary Screen Pagination Keys (item 18) to wake the screen and cycle through pages.
  2. If the screen remains dark, this may indicate no lines or contacts have been assigned to secondary screen keys.
  3. Line key assignments are managed in CommPortal under Account Settings > Devices > Set Keys. Contact your administrator if keys need to be reassigned.

Expansion Module (If Equipped) Not Showing Lines
The Poly Edge E Expansion Module connects to the right side of the E400 and adds 22 line keys per page across 3 pages for a total of 66 additional keys.

  1. Confirm the Expansion Module is firmly seated against the phone and the connector tab is fully engaged.
  2. If the module screen is blank, press the Page Keys at the bottom of the module to cycle pages.
  3. If lines assigned to the module are not appearing, log in to CommPortal, go to Account Settings > Devices, and confirm the module is recognized and keys are assigned.

WARNING: Do not force-connect or disconnect the Expansion Module while the phone is in an active call.
Disconnecting the module mid-call may drop the call.
