On my Smartcode Touchscreen, Only two digits illuminate on the touchscreen.
SecureScreen is enabled. SecureScreen is an added-security feature that displays random digits before you enter a user code to unlock the door. This feature ensures that there are fi ngerprints on all digits so that codes cannot be identifi ed by examining the touchscreen for fi ngerprints. If desired, this feature can be disabled by turning switch #4 to the off position.
