Nortel 1120e 사용자 설명서

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 

 option in the 

 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.

The Expansion Module for IP Phone 1100 Series (Expansion Module) 
text is rendered by the IP Phone; therefore, the selected language and 
font mappings on the Expansion Module mirror the selected language 
and font mappings on the IP Phone. For further information, see IP 
Phones Fundamentals (NN43001-368).
