12.2.2 Preserving UserSet settings when updating the Firmware

For devices that are capable of storing UserSet settings on the device itself (mvBlueCOUGAR-X/XD, mvBlueF←-

OX3, etc.) these settings will by default be preserved during ﬁrmware updates since mvIMPACT Acquire 2.9.1.

This may lead to slightly longer ﬁrmware update times. If UserSets are not used, and their persistence during

ﬁrmware-updates is not desired, the "Persistent UserSet Settings" in the Settings Submenu can be unchecked:

This will also accellerate the ﬁrmware update process.

12.2.3 How to disable CPU sleep states a.k.a. C states (< Windows 8)

Modern PC's, notebook's, etc. try to save energy by using a smart power management. For this several hardware

manufacturers speciﬁed the ACPI standard. The standard deﬁnes several power states. For example, if processor

load is not needed the processor changes to a power saving (sleep) state automatically and vice versa. Every state

change will stop the processor for microseconds. This time is enough to cause image error counts!
