The attachment selection menu is accessible by pressing the change attachment button in the bottom right corner on
the attachment description on the main screen.

Please be aware that it is NOT possible to use any other attachments, other than the attachments listed in a Gen 4 attachments list. Furthermore, due to obsolescence, it is also NOT possible to add any new load charts for new attachments to the Gen 4 system.
The change attachment button is highlighted below.
Once the new attachment is selected the full attachment details will be displayed for confirmation.
Once the attachment is confirmed, the Gen 4 will load the new attachment configuration files.
After the configuration
files have been loaded press the home button to return to the main screen.
