How Do I change Contrast On A 2GIG GC3 Alarm System?

There actually isn’t a way to change the contrast on the 2GIG GC3 control panel but users can adjust the brightness.

To adjust the brightness > press System Settings > enter the four digit master code, the 2GIG factory default master code is 1111 > select Screen > this will bring up the screen menu which displays; Brightness, Screen Timeout and Clean Mode.

The Brightness option allows users to control the brightness of the touchscreen when backlit. To adjust the brightness of the backlit touchscreen > highlight Brightness > slide the button to the right to increase the brightness or to the left to decrease the brightness. Press the left facing arrow to return to System Settings > press the left facing arrow again to return to the Home Screen.

Users can also adjust the Screen timeout to: Always on, 30 Seconds or anywhere from 1 minute to 10 minutes. Keep in mind if Always is selected the light is running off a battery and will use the most power with this setting. Press the left facing arrow to return to System Settings > press the left facing arrow again to return to the Home Screen.

To Clean the touchscreen > press the Clean “start” button. This provides a 30 second window to clean the touchscreen with a microfiber cloth. Press the left facing arrow to return to System Settings, then again to return to the Home Screen.
