Part 3 Using Support Functions
When the monitor detects an error condition, the monitor shows an error code on the display
screen. If such an error occurs during monitoring operation, an audible alarm tone also
sounds. Press the Alarm Silence button to terminate the audible alarm tone.
When an error code appears on the display, a number in hexadecimal representation indicates
the nature of the error. Additionally, Diagnostic Mode can be used to gain access to an error
code record, stored in non-volatile memory, of the last 10 error codes encountered. See
Chapter 5 Diagnostic mode for further details on Diagnostic Mode.
Each error code corresponds to a particular problem in the monitor. Recommended actions to
take when an error code is encountered are listed below.
