(F2) - Options (Press within System Input Screen)

A basic understanding of the following concepts is assumed. If further information is needed one might consider reading a detailed account of these principles in a layman's guide to master-keying.

Stepping may be designated per cylinder position. The default on the main generation screen is for all cylinder positions. In some cases the designer may wish to have certain positions with different steps. A SF:2 is the most common, but in some situations greater security is required - or cylinder wear prevents the use of smaller master pins.

For example:

SF: 13221	SF: 33333
A: 02520	A: 02520
A1: 15101	A1: 35220
A2: 25101	A2: 65220
A3: 35101	A3: 95220

Ax: 18101
Ay: 28101
