2. Save the indicator firmware HEX file to a location on your computer such as My Documents.
IMPORTANT! Confirm that the indicator firmware is in a hex file format where the file name
ends with .hex such as 225D.hex or if custom firmware such as B12345.hex or SO123456.hex.
Should the file be compressed, the file name will end with .zip such as 225D.zip. Zip files must
be decompressed before they can be loaded into the indicator. To decompress the file, save
the .zip file to a location on your computer that will be easy to locate like My Documents, then
open the file. The window will have an option to Extract all files. See Figure 4. Click on this and
use the folder extraction wizard to decompress and save the file(s). Ensure that you select a
location to save the file to such as My Documents so you can locate the file when using the
AVR programmer. See Figure 5.
