How do I restore Amulet OS for my monochrome GUI?

If your module has a touch panel, follow the steps below:

1. Go to File > Restore Amulet OS. Choosing this menu option opens the latest Amulet OS and then starts programming it into the Amulet's serial data flash.

-OR-

1. First load the file AmuletOSv3.3.5.uht from the \binaries\ subdirectory of the Amulet main directory. By default, the Amulet main directory is C:\Program Files\Amulet, however you may have specified a different path during the install.
2. If the Amulet is currently "dead", put the Amulet module in program mode (DIP switch 1 to OFF in the 5.7" or remove the Boot M jumper in the 3.8") and hit the reset button.
3. Next, program the file into Amulet Flash. After the OS is successfully loaded, the touchpanel calibration routine will appear. Before running the calibration routine, you must put the Amulet back in normal mode (DIP switch 1 to ON in the 5.7" or reinstall the Boot M jumper in the 3.8") After successfully calibrating the touchpanel, a screen allowing the setting of the display polarity appears. Hit the button to the right to toggle the display polarity.

If your module does not have a touch panel, see below: If you are updating a module that does not have a touchpanel, then you'll need to load the file AmuletOSv3.3.5_NT.uht instead of AmuletOSv3.3.5.uht. The regular OS requires touchpanel calibration upon loading. The _NT file does not have this requirement. After loading the "No Touchpanel" OS, if you need to change the polarity, you obviously won't be able to change it through the LCD, since you can't use the touchpanel to select the ""Toggle Display Polarity" button, but you can by going into the LCD Settings menu and either selecting your specific LCD from the list of LCD Types, or you can create your own custom LCD settings, including the display polarity and save that LCD type. After selecting the LCD settings for your specific display, you can then hit the Program Now button. Make sure that the "Force Touchscreen Calibration" checkbox is unchecked, otherwise you will be forced to run the touchscreen calibration before displaying anything else.
