You don't bother public with engineering stuff like "we have 1000 Wh power budget from the primary batteries, which will last depending on what happens when, and the different devices have different energy needs and we aren't actually sure what can happen but we prepare for as much as possible with the hope of at least something giving us some good results." They just switch off. We at least know where justsee switched off in being interested in the details: the expression "during a week" he understood as somebody promised him "exactly at least a week of entertaining news from the lander."
