It is normal for the PIM to reset under the following
conditions:

screen changes
insertion/removal of a USB device (USB memory
stick)
When the PIM resets, it is normal for all leads to
display red dashed lines for up to ten seconds. The PIM
icon with the red X is displayed during the PIM reset.

show leads off (red

periodically
PIM communications
have been lost due to
USB patient data cable
connection failure, or
defective leads are
connected to the PIM.
1 Check to see if the PIM icon (with the red X)
appears at the top right of the screen.
2 If the PIM is firmly attached, perform the PIM test
as described in “Patient Interface Module (PIM)
Test” on page 3-43. If the PIM Test fails, replace
the patient data cable. If the PIM Test continues to
fail with a new patient data cable attached, replace
the PIM.
3 If the PIM test passes, ensure that all lead wires are
fully seated in the PIM lead connectors.
4 Ensure that all lead wires are intact and that there
are no visible cracks in the lead wires.
5 Run the lead wire open and short tests, as
described on page 3-35.
