daytime period. In the evening, when the patient goes to bed, pressing and holding the EVENT
button for at least 5 seconds will store the time of going to sleep as a special event marker in its
memory. This is the end of the active and the beginning of the passive period. The LCD will display
an additional dot at the bottom in the middle, showing that this is now the passive period. The device
will not beep with normal activities during the passive period. In the morning, when the patient
wakes up, pressing and holding the EVENT button for at least 5 seconds will store the time of
waking up as a special event marker in its memory. This is the end of the passive and the beginning
of the active period. The additional dot will disappear from the LCD and beeps will return (if they
were not specifically disabled on programming the device). Knowing the exact time of these two
events, the statistical evaluation can be really precise. Should the patient forget to mark either special
event (or both), the evaluation can still be based on the event diary or oral information from the
patient.
Typical causes for this use: waking up and going to sleep (special), taking medicine, etc.
Interrupting a measurement
A blood pressure measurement can be interrupted by pressing the EVENT button, this way the cuff
can be deflated quickly. Such interruption is limited to the measurement in progress only and has no
effect on further operation. This use of the button will not set an event marker.

CardioVisions program. This helps service personnel to identify causes of an unexpected behavior,
result or error.
