IHAP-322-08 Overspeeding

Can anyone tell me how to implement Overspeeding on the IHAP-322-08? I just purchased one to replace my Ben-q 1640 and can’t figure out how to do so. With the Ben-Q I could record at least 50% faster on my TY and Ritek media and was under the impression that the Lite-on was capable of the same. Thanks
