WARNINGS
WARNINGS
CAUTION
If the monitor's settings are adjusted since they were last recalled or stored (manually, or via
synchronization if using an IP5), the User Settings key (see page 2-15) will be appended with a
plus symbol (+). The symbol will only be removed if the current settings are saved (see page 3-15)
or if different settings are recalled (see page 3-26). Always confirm the proper settings for the
MR400 and IP5 to ensure expected monitoring functionality.
Note
See Default Settings (on page 3-7) for information about the system's power-on setup.

Device Control

Menu commands that control parameter functions for patient monitoring are synchronized 
between the MR400 and IP5. Commands that do not directly control patient parameters (for 
example, printer functions) will only affect the IP5. Other control settings remain localized to the 
IP5 and are not synchronized with the MR400, including the alarm audio off and alarm audio 
pause functions, and the volume settings; see the IP5 IFU for a complete listing.
Note
If a systemic failure of the processing hardware, software or communications renders an intended
task incomplete and unperformed, a watchdog circuit will automatically shutdown power to the
WPU portion of the MR400. This will result in the removal of all patient data and displayed
information, and a continuous alarm will sound until power to the MR400 is turned off. If this
problem persists, contact technical support.
2‐4    System Overview                                                                                                                Expression MR400 Instructions for Use
The use model specifies one IP5 per MR400 system. If more than one IP5 is present on
the MR400 system, there is an increased risk of units within the system not
synchronizing and displaying incorrect or corrupted settings.
The MR400 should not be used adjacent to or stacked with other equipment. If
adjacent or stacked use is necessary, the equipment or system must be observed to
ensure normal operation in the configuration in which it will be used.
