About the EU24/EU24BL Expansion Module
Overview
The EU24/EU24BL Expansion Module is an optional device that extends the number of call
appearances and Feature buttons available on the telephone. The EU24 and EU24BL
Expansion Modules are identical in terms of features and functionality. The EU24BL has a
backlit display area and is used with different telephone models than the EU24, which does not
have a backlit display.
Use the EU24 with these Avaya telephones:
●2420 Digital Telephone
●4620/4620SW IP Telephone
●4625SW IP Telephone
Use the EU24BL with these Avaya telephones:
●4621SW IP Telephone
●4622SW IP Telephone
The expansion module has 24 buttons arranged in two columns. Depending on how they have
been programmed for your call processing system, these buttons can be call appearances,
which are lines for incoming and outgoing calls, or features like Call Forwarding.
Issue Date
This document was issued for the first time in May, 2002. This document was revised for
Issue 2 in April, 2005 to include the EU24BL Expansion Module. Procedures to adjust the
expansion module’s contrast and its viewing angle were also added for Issue 2.
This document was revised in November, 2006 for software Release 2.7 to add the 4625SW IP
Telephone.

Viewing the Alternate Display
Although the EU24/EU24BL Expansion Module supports an additional 24 Call Appearance/
Feature buttons, it displays only the button labels for one column of 12 buttons at a time. A
dotted line separates the left column from the right column. When you view the labels and icons
for the left column, the icons for any active or selected right column features display to the right
of the dotted line. To view the column not currently displayed, press the Alternate Display
button. You can alternately press any Call Appearance/Feature button on the column not
currently displayed. Doing so displays that column and selects the line/feature associated with
the button you pressed.
Selecting a Call Appearance/Feature Button
To select an available call appearance or feature, press the button next to the appropriate label
in the column currently displayed. If you select a button not programmed as a Call Appearance
or a Feature button, an error tone sounds.
If the desired call appearance or feature is not currently displayed, use the Alternate Display
button to access the additional Call Appearance/Feature button labels. See Viewing the
Alternate Display for more information.
Changing the EU24/EU24BL Contrast
On first-time startup, the display area contrast is set to a mid-level. To adjust it to better suit your
work environment and lighting, 15 contrast levels are available.
Note:
Note: You might not be able to distinguish between all 15 contrast level settings.
Some of the upper and/or some of the lower contrast level settings might appear
identical to adjacent settings. This is normal.
Changing the Display Contrast Using a 2420 Digital Telephone
1. With the EU24 attached to your phone, press the telephone’s Option softkey.
2. Select the Contrast Line/Feature button.
3. Press the Line/Feature button on either side of the line in which you see EU24. Doing so
