Usage
Stage Time and Override
Your AVU1500's SmartStage shutdown feature cuts power to your
connected home theater equipment in three stages during a power outage.
All of the AVU1500's rear-panel power outlets are assigned to one of
these three stages. While all of these rear-panel power outlets get battery
backup, different outlets/stages get different lengths of battery
backup time:
Power
Outage
Stage 1
Stage 2 battery-backup time
Stage 3 battery-backup time
The front-panel "Stage Time" button enables you to see how much
approximate battery-backup time there is for each shutdown stage. Each
time you press this button, the system will take one step forward through
four estimated battery-backup times:

Once you stop pressing the "Stage Time" button, the system will time-out
after five seconds and go back to showing Stage 3 information. After all,
your most critical devices are connected to Stage 3 outlets, so the Stage
3 battery-backup time is shown by default when the system is in normal
operating mode.
If you do not want your AVU1500's power outlets to shut down in stages
and prefer to supply battery backup to all outlets for the duration of the
battery's usable power supply, then you can override the staged shutdown
process. Pressing the front panel's "Override" button will turn the override
feature on or off. If the override feature is on, then there will only be one
estimated battery-backup time to view, override time: the estimated amount
of total time your AVU1500 can supply usable battery-backup power to
all rear-panel power outlets. In such a case, the "Stage Time" button is
disabled since shutdown will not happen in stages. Once the usable battery
power supply is fully consumed, all rear-panel power outlets will shut down
(lose power).
In all cases, the estimated battery-backup time is affected by what home
theater devices are on and how much power each is consuming. Any
change in power consumption will cause your AVU1500 to reestimate the
battery-backup time. In the event of a blackout, you will be able to see
the estimated battery-backup time and can choose to help increase the
battery-backup time by manually turning off less critical devices.
