PROGRAMMING OF VRAE
4 - 3
Security Level
There are three levels of security in the VRAE programming
mode to provide further protection against unauthorized
changes to the monitor alarm settings and other settings.
The
level 2
security allows a user to enter programming
mode without any restriction. This is the default security
setting. The
level 1
security requires a 4-digit password to
enter programming mode.
Level 0
security allows a user to
enter the programming mode without any password
checking, as in the level 2. However, level 0 security does
not allow a user to save any changes to the alarm limits, real
time clock, correction factor, user and site information, etc.
A user can still perform calibration with level 0 security.
The security level must be set using a PC (see Section 5.0
for details on setting up the security level).
Once inside the programming mode, LCD will display the
first menu. Each subsequent menu item can be viewed by
pressing the
[N/-]
repeatedly until the desired menu is
displayed. To enter the sub-menu of a particular menu, press
the
[Y/+]
key and the sub-menu will be displayed.
To exit the programming mode and return to the normal
operation, press the
[MODE]
key at any of the first tier menu
displays.
