About the Expansion Module for IP Phone 1100 Series

Adjusting the display

The Expansion Module is equipped with a graphical, pixel-based,
grayscale LCD display area beside the 18 line/feature keys (see Figure 1
on page 8). Each of the 18 physical keys on the Expansion Module has a
10-character display label. This label is set automatically, however, the
user can edit the label using the controls on the IP Phone.
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 affect the
Expansion Module. The Expansion Module and IP Phone do not have
separate contrast adjustments.
The type of power supply to the phone controls what is functional on the
Expansion Module for IP Phone 1100 Series. The Expansion Module's
backlight can only light when the local 48V power supply is present. On
the other hand, either local 48V power supply or Power over Ethernet
(PoE) to the phone will power all of the Expansion Module's other
functionality.
For more information, see the section "Adjusting the screen display
contrast" in your IP Phone User Guide.
