Display
The expansion module is equipped with a graphical, pixel-based, gray-scale liquid crystal display
(LCD). The LCD is located beside the 18 line/feature keys (see Figure 1 on page 18). Each of the
18 line/feature keys on the expansion module has a 10-character display label. This label is set
automatically, however, you can use the controls on your IP Phone to edit the label.
To adjust the display and contrast on the expansion module, use the Contrast Adjustment option in
the Telephone Options menu on the IP Phone. Any contrast changes you make on the IP phone
also affect the expansion module display. The expansion module and IP Phone do not have
separate contrast adjustments.
Whether the IP Phone is powered using local power or Power over Ethernet (PoE), the expansion
module has the same backlight settings as the IP Phone. The backlight timer only turns off if the
backlight timer is set.
For more information on how to adjust the display settings on the expansion module using the
menus in your IP Phone, refer to the user guide for your IP Phone.
