: The ECG and ECG/RESP self-test may be performed at any time as the lead selector
and pace pulse detection are inhibited during the check. The module will produce ECG test
signals at the beginning of the processing circuitry, and process the test signals in the same way
patient signals are processed. The test signals last about 30 seconds and then the display returns to
the normal monitoring mode.

If the module is functioning correctly, the following heart rate and respiration are
displayed without the alarms being activated:

The check for these modules is started every time the system is switched ON and
checks the complete module circuitry, including the sensitivity detection circuit.

: The test signals last about 30 seconds and then the display returns to the normal
monitoring mode.
The M1006A Pressure self-test may be performed at any time as the input switch switches the
CAL divider to 0 mmHg, and the pressure test signals bypass the sensitivity detection circuit.
From here, the signals are processed in the same way as the patient signals.
The M1006B Pressure self-test may be performed at any time, as the signal is output from a
microcontroller. From here, the test signal is processed in the same way as a patient signal, testing
the complete signal path from the module to the display.
