A few people often ask us how to adjust the contrast on their Norstar phone display.
Thus I will attempt to explain the process here.
To Change the Contrast of the Display:
1. Dial the Feature button, then * 7
2. Press the number keys 1 – 9 to your desired brightness level
3. Press the OK softkey
Some models will only go to number 4.
