Follow the steps below when operating the MR400.
System Power-up and Communications Verification
Always perform operational verification prior to use and during monitoring by ensuring
proper communications between the MR400, the wireless modules and IP5 (if equipped).
Failure to ensure proper communications can result in the loss of patient monitoring and the
loss of data transfer in networked systems equipped with an IP5. If a device fails to function
properly, remove it from use and contact technical support.
The MR400 reaches an operational state within 60 seconds after power‐up and attains full
measurement accuracy according to the equipped options:
When any displayed warm‐up message disappears, the MR400 is ready for use.
To apply power to the MR400 and verify system communications
3‐4 Getting Started Expression MR400 Instructions for Use
Press the power switch
Ensure that the wECG and wSpO2 modules (and IP5, if equipped)
have established good communications, and that sufficient power
exists for the MR400 and the wireless modules. Also verify proper
operation of the patient parameters.
See System Power‐up and Communications Verification, below.
After approximately 2 minutes when equipped with the CO2 LoFlo option
After approximately 10 minutes if equipped with the AGENT option.
Ensure that batteries are installed in the wECG module (see page 1‐
Check the battery indicators on the wECG module to ensure that
enough charge exists in at least one of the installed batteries:
• Green battery indicator = Charge sufficient; proceed to step 4.
• Red battery indicator = Charge low; proceed to step 3.
See page 2‐9 for details. (Also, you can reference the status
information pane; see page 2‐16.)
According to the red battery indicator(s) present on the wECG
module, insert a charged module battery into the corresponding
battery bay(s) and then recheck the battery indicator(s) to ensure a
sufficient charge before proceeding; see page 1‐24.
