Changing the Display Contrast

On first-time startup, your 4622SW IP Telephone’s display area contrast is set to a mid-level.
To adjust it to better suit your work environment and lighting, 15 contrast levels are available.

NOTE: If you have a Feature Key Expansion Unit (EU24/EU24BL) attached to your phone, you can also adjust its contrast with this option.

You might not be able to distinguish between all 15 contrast level settings. Some of the upper and/or some of the lower contrast level settings might appear identical to adjacent settings. This is normal.

1. Select the Contrast Control option from the Options Main screen (accessed by pressing the phone’s Option button).
2. If you do not have an EU24/EU24BL installed, skip this step and proceed to Step 3.

If you have an EU24/EU24BL attached to your phone, press the Line/Feature button on either side of the display line on which you see 4622SW. Doing so identifies that you want to adjust the telephone’s display contrast.

3. To brighten the contrast, press the Right Arrow softkey until you reach the desired contrast level. To dim the contrast, press the Left Arrow softkey until you reach the desired contrast level.

Each softkey press results in the level being increased or decreased, depending on which arrow softkey you press. Chevron symbols provide visual confirmation of the current level.

4. Save the contrast level you set by pressing the Save softkey, or, to restore the previous setting without changing the contrast, press the Cancel softkey.

The first Options Main screen displays.
