Controller / Reader Brightness Control
The C4 Controller has a status light that can be made brighter or darker as the application
demands. Mostly the default value is fine. However, in some unsupervised locations, it may attract
the attention of vandals and it may be preferable to turn the brightness down to 0.
Values
• 0 = 0ff to 9 = 100%
Default Value
• 5 = Medium Brightness
