flash), while the practitioner attends to the patient and Monitor. Silence mode resets automatically
after 30 seconds, or when the patient's condition returns to within the preset alarm parameters.
NOTE: Certain alarms alert the operator to abnormal system conditions or internal system
failures. Alarm conditions, error codes and suggested operator action are reviewed in
the Troubleshooting section of this manual.
Measuring Blood Pressure
Setting the DEFAULT Inflation Pressure Preset Level
The default cuff inflation level for blood pressure measurements is set in the Monitor’s internal con-
figuration menu. The factory default level is 160 mmHg. If desired, the default pressure preset can
be changed by following these instructions:
• Turn the monitor off.
• Press both the POWER button and the START button simultaneously. The Monitor will enter
it’s internal configuration mode.
• Press the REVIEW button 6 times. “PrP” will appear in the systolic display, and the default
pressure preset level will appear in the diastolic display.
• Press the SET (arrow up and arrow down) buttons to cycle through the seven options
available: 120, 140, 160, 180, 200, 240 and 280 mmHg.
• When the desired pressure preset level is illuminated, press the REVIEW button once to
save this change.
• Turn the Monitor off.
• When the Monitor is turned on, the new pressure preset will be established as the default
level. The Monitor will always revert to this pressure preset level, except in the
circumstances noted below.
NOTE: In Manual Blood Pressure Operating Mode, the Monitor will inflate to the default
pressure preset level. However, if a BP measurement is initiated within one minute of
a prior BP measurement, the Monitor will inflate to a level which is 40 mmHg above
the previous systolic reading.
In Automatic Blood Pressure Operating Mode, the Monitor will inflate to default pressure preset
level for the initial BP determination only. After the initial measurement, the Monitor will inflate to a
level which is 40 mmHg above the previous systolic reading.
CAUTION: When measuring blood pressure on children younger than age 3 it is recommended
that the Pressure Preset (initial inflation pressure) be set at 160 mmHg or lower.
Blood Pressure Cuff Selection Criteria
NOTE: A large Adult size cuff is included with your Vital Signs Monitor. A full range of cuff
sizes are available (as accessory items) however, the Large Adult cuff will fit the
majority of adults and give the most accurate blood pressure measurement.
Research has shown that an undersized cuff will overestimate the true blood pressure by as much
as 10 to 30 mmHg. Please refer to the reference markings located inside the cuff for correct cuff
sizing. When there is an area of overlap whereby you could use a smaller or larger cuff, it is strongly
recommended that you use the larger size cuff.
