11.1 Introduction
Ensuring that your VK204-25 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 VK204-25 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.
