Using Checkme

Prior to Use Before using ECG

Before using Daily Check or ECG Recorder function, pay attention to thefollowingpointsin order to obtain precise measurements.

• If your skin or hands are dry, moisten them before taking the measurement.
• During the measurement, do not touch your body with the hand with which youare taking the measurement.
• Please note that there must be no skin contact between your right and left hand .Otherwise, the measurement cannot be taken correctly.
• Stay still during the measurement, do not speak and move.
• If possible, take the measurement when sitting instead ofstanding.

Before using Oximeter

Before using Daily Check and Oximeter function, pay attention to the followingpointsin order to obtain precise measurements.

• The finger inserted in SpO2 sensor must be clean.

• Any of the following conditions may cause inaccurate measurements, including but not limited to:

  • Flickering or very bright light;
  • Poor blood circulation;
  • Low hemoglobin;
  • Hypotension, severe vasoconstriction, severe anemia or hypothermia;
  • Nail polish, artificial nails;
  • Any tests recently performed on you that required an injection of intravascular dyes.

• The Oximeter may not work if you have poor circulation. Rub your finger to increase circulation, or place the SpO2 sensor on another finger.

• The Oximeter measures oxygen saturation of functional hemoglobin. High levels of dysfunctional hemoglobin (caused by sickle cell anemia, carbon monoxide, etc.) could affect the accuracy of the measurements.

• The pleth waveform displayed on the device is normalized.
  **** Warnings and Cautionary Advices

• Limit finger movement as much as possible when using the Daily Check or Oximeter, which might result in incorrect reading or analysis.
