Certain critical activities which can be accessed from the
keypad are initially unrestricted. Entry codes can be
initiated at any time so that these activities are protected
from unauthorized access.
8.3.2 DEFINITIONS
USER NUMBER: Single digit number between 1 and 8. This
number is used to establish different authorized users and
is printed on reports generated by each user. User number
1 must be established before the other numbers can be
used.
ENTRY CODE: Four digit code between 0001 and 9999.
This is the access code which is assigned to each user and
is required to access critical menu items which result in
changes to the system.
SPECIAL USER NUMBER: The special user number 9 is
reserved for access to the diagnostic mode of operation.
DIAGNOSTIC CODES: When the user number 9 is used to
access diagnostics, four digit entry code numbers are used
to select various diagnostic activity.

same manner.
5. When an entry code has been established that
code must be used to access the controlled
sections of the menu.

Sentry functions. Users 6 through 8 are
restricted to calibration activities only.
