User's Guide
Optional Expansion Consoles for use with the 48-Key Feature Phone
Note: Of the systems covered in this User's Guide, the Second Expansion Console works with only
IVX X-Class.
Your ESI 48-Key Feature Phone can support up to two optional Expansion Consoles, for a possible total
of 120 additional programmable feature keys.
The 60-Key Expansion Console connects directly to the phone, while the Second Expansion Console
connects to the first Console.
You program each Expansion Console's keys just as you do the programmable feature keys on your
ESI Feature Phone, using either direct or traditional programming (see page C.2).
Note: Only one key can exist per extension, feature or operation. If you program a second key for the same
extension, feature or operation, this automatically erases the first key so programmed, thus making it
available for a new extension, feature or operation.
Hint: You may find it easier to write in the names on the overlay before you program the keys and attach the
overlay to the Console.
Hint: On any of these phone varieties (including the Expansion Consoles), you can perform direct
programming by holding down a programmable feature key for at least two seconds (similar to how you
might program a car radio button). This isn't applicable to the fixed-feature keys which, as their name
implies, are already programmed.
