Congratulations on the new embroidery machine.
The fonts need to be in the format of the embroidery machine, pes and within the hoop size the machine is designed for.
You will need to see the font and additional software is needed. In a pinch, download Pulse Ambassador (it's free) for viewing and editing.

Select the font and then save as (a new file) when finished. Send the file to the embroidery machine.
