Troubleshooting

Problem	Possible Reason	Resolution
Device doesn’t power on when START/STOP button is pressed. or Cuff does not inflate. (display remains off)	Batteries completely drained.	Replace batteries with new Duracell AAs.
	Batteries inserted with incorrect polarity.	Remove batteries and reinstall them making sure the + and − polarity symbols on the batteries match those inside the battery compartment.
Cuff does not inflate. (display turns on)	Cuff not plugged in correctly.	Make sure the connector on cuff tube is plugged all the way into the device.
Cuff doesn’t form a loop around arm.	Cuff not assembled.	To form a loop: pass the end of the cuff furthest away from the tubing through the long metal D-ring. The smooth side (without the hook and loop fasteners) should be on the inside of the cuff loop.
Readings too high or low. or Readings vary significantly between measurements.	Cuff not positioned correctly.	Review instructions on Securing the Cuff and retry measurement.
	Movement during measurement.	Place your arm on a table with your palm facing up. The cuff should be at the same level as your heart. Make sure you stay still and don’t talk during measurement.
Measurement results differ from those measured at the doctor’s office.	Measurements taken in a medical / professional environment (white coat effect) may affect your blood pressure.	Measurements taken in a more relaxed, home environment may avoid effects experienced in clinical settings. Continue taking readings as usual. If in doubt, contact a medical professional.
Error code shown after measurement.	Measurement accuracy may be affected or transmission may have been unsuccessful.	Consult the error code table below for more information and further instructions.

Blood Pressure and Pulse

Blood pressure is represented by two numbers:

1. Systolic pressure: indicates the maximum pressure blood is exerting against the artery walls when the heart beats;
2. Diastolic pressure: indicates the minimum pressure blood is exerting against the artery walls while the heart is resting between beats.

An additional useful metric is the pulse rate, which indicates the number of times the heart beats in a minute.

This device measures blood pressure using the oscillometric method. Before each measurement, the device establishes a zero point based on the atmospheric pressure. The cuff is then inflated, and the device measures the oscillations in pressure created by the user’s heartbeat.

Irregular heartbeat is indicated by the device () if there is a 25% deviation from the average pulse rate between three, or a deviation of 15% between five heartbeats.

While this may not be a reason for immediate concern, contact your medical professional if you see this symbol frequently.
