Please don't take this the wrong way, but this question smacks of "too lazy to read the manual" or "can't read the manual". So I will assume that the real issue is you somehow lost or don't have the manual in the first place (I assume you can read since you obviously can write). So here is a link to the online PDF for the EH50 manual:

Dubbing is covered on pp 43 - 49. Good luck and check back here if that doesn't help.
