Shift/System Check is running.
If a )DLOXUH or 6HUYLFH8QLW message is displayed, or if an unexpected 1RW
7HV W H G  result is displayed, check that the test is set up correctly. Make
sure that:
the paper is in the printer
the test load is attached
a Data Card with enough space is inserted into the HeartStart
XLT
a charged battery is inserted into the HeartStar t X LT
Run the Shift/System Check again, ensuring that no one touches any
of the controls on the defibrillator unless prompted to do so.

of the screen and the message 'DWD&DUG)XOO appears at the top of the
screen. Replace the Data Card and perform the Shift/System Check
again. If the message6HUYLFH8QLWcontinues to appear, do not use the
device and call for service.
