                     rr is DD revision number

[Capabilities file]
 ddrrff.cff          dd is device revision number
                     rr is DD revision number
                     ff is Capabilities file revision number

4. Handling cautions

Correct Capabilities file must be selected according to the type
or option code of the instrument. In case a wrong Capabilities file
is selected, it may generate an error at the downloading etc due 
to the discrepancy in the function.
