LCD Contrast Adjustment
The contrast of the LCD screens on IP and digital display endpoints is adjustable. Eight differ-
ent contrast levels are available. Examples follow for a two-line endpoint and a six-line end-
point. For instructions to adjust the contrast on a specific endpoint, refer to the User Guide, as
identified in “Endpoint User Guides” on page 358.
Examples:
To adjust the LCD contrast on the Model 8520, a two-line display endpoint:
1. While the endpoint is idle, locate the contrast control wheel on the back, upper-right
section of the endpoint.
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 endpoint:
1. While the endpoint is idle, press the Special button ( ) and enter the LCD Con-
trast feature code (303).
2. Select LIGHTER or DARKER on the menu buttons.
OR, Use the Volume button to make your selection.
OR, Press the level (1–8) you want.
3. Press the Speaker button or ACCEPT to save your change. The Model 8620 IP endpoint
is equipped with a contrast control knob to adjust the contrast level. This knob is
located on the back of the endpoint and can be adjusted while viewing the display.
Node and Circuit Number on Power-Up
To aid in installation and troubleshooting procedures, display endpoints show their identifica-
tion for 5 seconds when power is turned on, when the system is reset, or when the endpoint
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-second identification display, the endpoint returns to the appropriate display, depending on
its current status.
