dCS Lina dac power consumption sleep mode

Phile I am confused by your answer. You give three options : On, Standby and Sleep. However all of the dCS units I have owned and the Lina DAC manual show On, Sleep and Off. If the power consumption is 0W then surely this indicates Off not Sleep ( Sleep indicates that core functions remain powered)?

As I am not a Lina owner the reason eason I ask is combining this with James response regarding battery use for the volatile memory in Vivaldi. He says :

So I am assuming the means off and not sleep. However he refines the matter to talk about battery use only when the unot is fully powered off. To me that means when the unit is powered off by the rocker switch on the rear not the front panel. Grateful if you could clarify. I apologise for mashing up two threads but I could not think of another way.
