Low Battery Warning
The message
/RZ %DWWHU\ is displayed on the HeartStart XLT when the battery
is low and needs recharging. This message indicates that the battery has suffi-
cient remaining capacity to provide only about ten minutes of monitoring time
and six shocks before the HeartStart XLT shuts off. Replace the battery as
soon as possible.
If the power is off for less than 2 minutes, while you change the battery, the
HeartStart XLT assumes that you are continuing to treat the same patient. It
continues to store data on the Data Card and append events to the existing
Event Summary. Alarms set prior to the power loss remain active.
If power remains off for more than 2 minutes, the HeartStart XLT assumes
you are treating a different patient and assigns a new incident number. A new
Event Summary begins with the next event.
