Entering 0 For Key Number Resets System

[3.05] In prior version 3 releases, inadvertently entering 0 as the key number when setting up Feature Keys would reset the system. This would occur while using Menu + Key Assignment + Feature Keys (Menu + 51) or using the #KP legacy method. The reset is now corrected.

Feature Key User Programming Restricted

[3.00.32] A keyset with access level 3, 4, or 5 allows the user to set up their Feature Keys in the Menu + Key Assignments sub-menu. In prior versions, this capability was restricted to keysets with access levels 4 and 5 only.
