Power Save: Disable the Power Save Feature

This section briefly describes the Power Save feature and provides instructions for
using either of the following methods to disable the Power Save feature:
Disabling with conditional access — Using the conditional access method to

disable the Power Save feature allows you to disable the feature for an individual
DVR. This method is recommended for all set-top types and is required for
disabling the Power Save feature on set-tops that use DVR Releases 1.1.6a5 to
1.4.0.
Disabling with global access — Using the global access method to disable the

Power Save feature allows you to disable this feature for all DVRs in your
system. This method is required for all set-tops that use DVR Release 1.4.2 and
later.
What is the Power Save Feature?
The Power Save feature is intended to increase the life expectancy of DVRs. When
the Power Save feature is enabled, the SARA client starts monitoring for user activity
beginning at 1 a.m. If no activity is detected for 10 minutes, the client displays a
message that notifies the subscriber that their DVR will automatically enter power-
save mode in 5 minutes.
After the additional 5 minutes elapse with no user activity, the Power Save feature
spins down the hard disk drive in the DVR and activates a screen saver feature. (In
releases prior to DVR 1.5.2, the Power Save feature behaves differently following 5
additional minutes of inactivity.)
Note: The mechanism used to disable spin down was changed in DVR release 1.4.2.
As a result, the spin down feature will be enabled after the upgrade from older DVR
releases.
However, if a subscriber is actively using the DVR (for example, presses any key on
the remote or any button on the front panel at least once every 2 hours), the set-top
will continue to operate normally and the Power Save feature will not activate. Even
after powering off the set-top or spinning down the hard drive, scheduled
recordings will occur.
