file and use it setup another extender by dragging it onto the file window
and overwriting it.
Upgrading a Local Unit
Drag the Local firmware file provided onto the window. After a few seconds the window
display should refresh and the new firmware version displayed by file ‘LOC_xx’
If the window does not refresh (will not on some OS,) and the dragged upgrade file is still
shown, then you may need to re-power the Local Unit (by disconnecting the USB cable) and
view the drive folder again.
If the ‘LOC_xx’ file displays as ‘LOC_BAD’ the upgrade was not successful. Try again or
call technical support.
