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.
