During experiment 52 tasks in total (including activity with the Electron-VM electrical trainer) are generated. 51 tasks are successfully solved. Views generated of the ONS and times expended on its localization are given in Table 2. Results of the crewmember action efficiency estimation in the ONS localization are presented in Table 3.

The typical results of experiments are shown on Figure 19 and Figure 20.

Localization of the arisen ONS is made by each crewmember with the use of the on-board instruction from the operator's workplace disposed in the Main Control Board. In this case both a rigid copy of the on-board instruction, and its electronic version which is available in a format \*.PDF on Operator's Terminal 1 and Operator's Terminal 2, can be used without

With a task of elimination of leakages in the PMM illuminators conducted from 06.29.09 to 07.08.09, the crew has failed. The reason is easing of attentiveness and fatigue of crew at the final stage of the experiment.

Commissioning of Electron-VM electrical trainer has been successfully conducted by the 06.25.09, operator 1002.
