Optional 60-Key Expansion Console for use with the 48-Key Feature Phone
The 60-Key Expansion Console adds 60 more programmable feature keys to your 48-Key Digital
Feature Phone.
You program the Expansion Console's keys just as you do the programmable feature keys on your ESI
Feature Phone, using either direct or traditional programming (see pages 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: 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.
