Notes
Use only with the specified battery charger.
The main batteries must always be inserted and the reserve batteries must always be
switched on to prevent loss of patient monitoring during a power outage. If main batteries
are not inserted and if the reserve batteries are not switched on, then during power outage
unsaved user settings will revert to factory defaults.
We recommend plugging the MR400 into a backup generator or equivalent means to
prevent a lapse in patient monitoring during a power loss.
