2.5 Manual Override
The Manual Override is provided to allow the GLK19264-7T-1U to be reset to some of the factory
defaults. This can be particularly helpful if the display module has been set to an unknown baud rate or I 2 C
slave address and you are no longer able to communicate with it. If you wish to return the module to its
default settings you must press the bottom left button at power up. Please see figure 19.
