4.6 Password Security Protection—
The <PASSWORD> Menu
MJ-5 security allows unrestricted read access to any data
item while providing password security against changes
and resets.
4.6.1 Overview
MJ-5 password protection is a hierarchical system,
consisting of a "System Key" that provides a level of
protection for the security system itself, and two Levels of
security for MJ-5 data items:
1. A Level 1 password enables the change/reset function;
if a valid Level 1 password is entered, any data item
(which is not further protected by Level 2) can be
changed or reset.
