the system automatically saves the parameter that was selected as the
default display parameter. The parameters that are available for display
are:

Parameters
The parameters describe the Avaya RS9 system operation. Some useful
parameters are input and output voltage, input and output current, and
battery voltage. The UPS measures or records many other parameters.
Some are operator-adjustable, such as the local date and time and
various operating limits. All parameters are password-protected.
Although every operating condition and parameter is accessible through
the front panel display, you may change a value
only
if you have entered
the correct password to allow you to change it.
NOTE
After 10 minutes of inactivity, the UPS automatically deletes any active
password level and returns to the normal running display.
Changing Parameter Settings
The method of changing any operating parameter follows the same
procedure as setting initial parameters, as described in “Initial Startup
Parameters” on page 27.
Use the Menu map (Figure 26 on page 40) to find the parameter you
need to change, and move through the menu structure until the
parameter name appears on the display.
