5.3 Low Power
Low power mode helps to further reduce power consumption when the scan engine is in
standby mode. When the scan engine shifts from standby mode to low power mode, all scan
engine settings are retained.
5.3.1 Enable/Disable Low Power Mode
When you enable low power mode, you can configure the transition time. Transition time is the
amount of time the scan engine remains in standby mode before it changes to low power mode.
The default setting for transition time is 5 seconds.
