LCD Contrast Adjustment
The contrast of the LCD screens on IP and digital display phones is adjustable. Eight different
contrast levels are available. Examples follow for a two-line phone and a six-line phone. For
instructions to adjust the contrast on a specific phone, refer to the phone User Guide, as identi-
fied in “Phone User Guides” on page 6.
Examples:
To adjust the LCD contrast on the Model 8520, a two-line display phone:
1. While the phone is idle, locate the contrast control wheel on the back, upper-right sec-
tion of the phone.
2. Adjust the contrast of the LCD screen by turning the wheel clockwise (lighter) or coun-
terclockwise (darker).
To adjust the LCD contrast on the Model 8560, a six-line display phone:
1. While the phone is idle, press the Special button ( ) and enter the LCD Contrast
feature code (303).
2. EITHER, Select LIGHTER or DARKER on the menu buttons.
OR, Use the Volume button to make your selection.
OR, Press the desired level (1–8).
3. Press the Speaker button or ACCEPT to save your change.
Node and Circuit Number on Power-Up
To aid in installation and troubleshooting procedures, display phones show their identification
for 5 seconds when power is turned on, when the system is reset, or when the phone line cord
is first plugged in (or removed and replaced). The extension number and assigned username
appear on the top line of the display, and the node number and circuit number appear on the
bottom line (for example, circuit 1.1.1 on node 2 would appear as 2:1.1.1). After the five-sec-
ond identification display, the phone returns to the appropriate display, depending on its current
status.
