About the EU24/EU24BL Expansion Module

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:

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.
