Note
The model numbers in this manual
call out "-XX-Y" for the suffix of the equipment model number. The wild cards are
defined as follows:
"X" is a number and the one
number in the model number representing a style code; form, fit, and
function are not changed, and these numbers have no bearing on compliance.
"Y" is a letter, and the one
letter in the model number representing a pedigree; form, fit, and function
are not changed, and this letter has no bearing on compliance.
