disconnection, displays the relevant messages at the location of the signals on the screen (Figure 1-2).
If any of the R, L, or F electrodes are disconnected, the messages Check R, Check L, and Check F
are displayed.
If any of the chest electrodes are disconnected, the message Check Cx is displayed (x from 1 to
