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.
