I have never worked on those, but thinking maybe see if there is another set of beeps right after the first two. It will be pretty quick and if you wait too long it will go into programming mode. However, If you have a hobbywing program box, it should be able to connect to this ESC. You will not be able to upgrade firmware or use computer to change settings, but you may be able to set it up with the box. If you have one that is.
