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, i.e. do not use finger nail
polish/paints.
Vigorous exercise and electrosurgical device
interference may affect the measuring
accuracy.
Nail polish may affect the measuring
accuracy, and too long fingernail may cause
failure of measurement or inaccurate result.
Existence of high intensive light sources,
such as fluorescence light, ruby lamb,
infrared heater or strong sunshine, etc. may
cause inaccuracy of measurement result.
Please put an opaque cover on the sensor or
change the measuring site if necessary.
If the first reading appears with poor
waveform (irregular or not smooth), then
the reading is unlikely true, the more stable
