13 Data Security
13.1 Introduction
Ensuring that your GLK12232-25 display’s exactly what you want it to can be the difference between a
projects success and failure. This is why we incorporate features such as Data Lock into the GLK12232-25
With this new feature you now are in control over of how and when settings will be changed so there is no
need to worry about the module acting exactly like you expected it to because all the settings may be locked
and remembered for the next power up.
