When using an IP5, make sure that the content of the User Settings option matches that of
the MR400 option, and that the same option is selected as the default setup on both systems
(see page 3-26). This is important because the device first booted will determine the power-
on settings of the system (that is, the MR400 and optional IP5).
Viewing the Displayed Information
The high resolution touch screen LCD facilitates waveform analysis and vital sign numeric
interpretation, with important display elements which are designed to be legible at a minimum
distance of 1 meter by users with a visual acuity of 20/20. When using the MR400, always adjust
the viewing angle of the touch screen to complement your line of sight and always ensure that
your view remains unobstructed.
Never apply unnecessary force to the touch screen as it can result in damage or failure.
To change the language displayed by the MR400, see System Config page 3-30.
At power up, the MR400 will automatically set all monitor setup options as determined by the
default selection in the Edit User Settings menu. By default, the factory settings are used when
the system is turned on, unless a custom setting has been selected. Also, as discussed earlier, due
to the use model, the power‐on default settings for the MR400 can depend upon a
communicating IP5 and the start‐up sequence of the devices.
Default Setting Indications
The User Settings key indicates the current default setup (where the plus symbol [+] indicates
that changes have occurred) and it allows you to select a factory or a stored user setup; see page
When a menu is displayed, the default will be highlighted or will appear with an asterisk. For the
factory default settings, see the menu listings throughout this IFU.
