Touchscreen Calibration mode: This mode allows you to recalibrate 
the touchscreen. Units without DIP switches have a Calibration button on 
the system toolbar. 
Hide System Toolbar: Hides the arrow in the bottom-right corner of the 
screen that accesses the System Toolbar (same as “Hide System Toolbar” 
in System Parameters and LB9020). 
Boot Loader mode: This mode forces the OIT to not execute the 
project. This mode is used when replacing or reinstalling the operating 
system. All units have an Upgrade Firmware button in the system menus. 
Contact Maple Systems for more information. 
Fusing Requirements 
If the display does not come on within two seconds of power up, remove 
power. An internal fuse (except HMI5043L) will prevent damage if the 
polarity of the DC power is incorrect. Check wiring to insure proper 
connections and try to power up again.
