Before performing the self-test, turn the channel output off and disconnect test
leads and cables from the terminals.

In this condition, the Emergency dialog box is displayed on the gray
background screen, however this is not shown in the remote state if the remote
display is set to OFF. And the ERR indicator turns on and the On/Off switch is
not effective.
