Firmware Upgrade
One of the functions of the SD card is to facilitate firmware upgrades. As with all software-
based music devices, from time to time there may be a new JM4 firmware release. This may
be due to new features and functionality, or simply an improvement to the user interface.
Should a new firmware upgrade be released, here’s how to bring your JM4 up to date:
Download the new firmware file to your computer from www.line6.com. •
Using an SD card reader, copy the file to a freshly formatted SD card. •
Insert the SD card into your JM4, press • SAVE and navigate to Firmware Upgrade.
Press R Arrow then Up Arrow “Yes” to confirm; the process will begin immediately. •
When the progress bar reaches 100%, your JM4 will be reboot and be up to date.
