Connecting your ESI phone
Depending on which ESI phone you have, use the appropriate diagram (below) to connect it. Each diagram
represents the panel on the phone’s underside.
Notes:
The “Top of phone” and “Bottom of phone” references in these diagrams show the correct vertical
orientation of the phone —
i.e.,
the part with the display is the top.
When the phone is in the highest upright position, use the wall-mount hook located under the handset to
secure the handset when you’re not using the phone.
