How do I change contrast on an L5200 security system?

The Honeywell LYNX Touch L5200 wireless alarm panel is a graphic touchscreen. In the panel settings you can adjust the contrast, brightness and volume of the sounder. First, press the home button beneath the touchscreen. Then click 'Security' followed by 'More' on the bottom right. You will see a gear icon labeled 'Settings.'

When you click into Settings you will see a slider bar that allows you to adjust the contrast on touchscreen. Depending on the environment and available lighting you can select the brightness and contrast that works best for you. Make sure to click 'SAVE' at the bottom right before returning to the main menu. If you do not save it will not lock in any of the changes made.
