4 ADDITIONAL ADVICE FOR OPERATION
• The finger should be put properly and correctly.
• Avoid shaking finger as possible as you can during measurement;
• Do not put wet finger directly into sensor.
• Avoid placing the device on the same limb which is wrapped with a cuff for
blood pressure measurement or during venous infusion.
• Do not let anything block the emitting light from device.
• Electrosurgical device interference may affect the measuring accuracy.
• Using enamel or other makeup on the nail may affect the measuring accura-
cy.
• If the first reading appears with poor waveform (irregular or not smooth), then
the reading is unlikely true, the more stable value is expected by waiting for a
while, or a restart is needed when necessary.
