Adjusting Keypad Display Contrast

The contrast of your Guardian Keypad display can quickly and easily be adjusted with a Phillips screwdriver.

In this example we can see the display is too light and the text is barely visible.


To adjust the contrast, open the keypad so that you can see the back side of the circuit board. Near the locking mechanism locate a white phillips screw. This is the contrast adjustment dial.

Clockwise: Lighter
Counter Clockwise: Darker


Adjust the display to the desired levels and then close the keypad.
