[Elecraft] On K3 erase 'AF REC'

[Sam Bridges]

Hello Guys:
    I have been fiddling with my K3. I have lately enjoyed the 'AF REC' and 'AF PLAY' feature...lots of fun. However how can one erase 'AF REC' so I will start at the beginning of the 90 sec reel? I know when I rec I dub over what is there but there seems to sections and gaps and then more stuff until the end. Is there a 'CLEAR' which also points to the beginning?
