Insert a USB drive containing the firmware upgrade into the USB port on the back of the main unit.
Please be careful to not disconnect the power or remove the USB drive while upgrades are being applied. The
main unit will turn off automatically after completing the firmware upgrade.
When software is upgraded, settings you have made will return to their default (factory) settings. We recommend
you write down your settings so that you can easily reset them after the upgrade.
If the firnware fails to upgrade, we recommend formatting the USB data in FAT16 and trying again.
For upgrading purposes, do not format USB data in NTFS because it is not a supported file system.
Depending on the manufacturer, the USB may not be supported. ▪
