The cuff deflates during a measurement and “Safety Rule Violated” is
displayed.
There may have been an overpressure condition. For safety reasons, the cuff
will deflate if the device detects a very high pressure in the cuff, or if a significant
pressure is held for a long period of time.
The screen is completely white when I turn the device on.
The screen flickers when I turn the device on.
The device resets by itself.
Check that an appropriate AC adapter is being used.
I get the message “Cuff Too Tight or Kinked Hose” when trying to take a
measurement.
The device is having trouble inflating the cuff. Ensure that the cuff is on firmly
but not tightly, and that the hose to the cuff is not kinked, compressed or blocked.
I get the message “Invalid Signal” after taking a measurement.
This can occur when the signal is too noisy to process. Ensure the cuff is
applied firmly and the subject remains still during the measurement.
The signal is consistently very noisy (SNR < 6) even under ideal
measurement conditions.
There may be a slow leak in the pneumatic circuit. Check for damaged air
connectors, split hoses or punctured cuffs. You may wish to use a different hose
and cuff set to verify the problem.
If the problem persists, contact Uscom.
The measured blood pressure is unexpected.
The measurements change a lot each time they are measured.
Ensure that good blood pressure measurement practice is being followed as
described in Section 2.1 Preparing for a measurement. Multiple successive
measurements may be used to calculate an average value for all parameters.
