Operation Information Codes and Error Codes
2.4 Information Codes and Error Codes
In addition to numeric values for the monitored parameters, the digital LED display of the
Duo provides information codes and error codes to indicate the operational status of the
monitor.
• Codes that refer to the operational status of the monitor are preceded
by a capital letter “E”.
• Codes that indicate that the device is in Maintenance Mode are numeric only.
Some codes refer to a particular parameter function and are displayed in the associated
parameter tile. (NIBP codes are displayed in the Sys. section of the NIBP parameter tile.)
Information codes, referring to the general operational status of the monitor and not to a
specific parameter, are displayed in the Information Codes tile. All codes display until the
condition is removed or, for one-time error codes, until the Clear/Next Patient key is pressed.
If multiple codes exist simultaneously, then each code will cycle through and display for a
duration of 1 second.
Information codes and error codes listed in the following table can generally be resolved by
the user. However, some error codes may require resolution by a qualified service
technician.
NOTE: Information codes and Error codes that are marked with an
asterisk (*) are one-time codes that can be cleared from the
display by pressing the Clear/Next Patient key.
