• This is a precision instrument. To avoid the possibility of it being dam-
aged, the instrument should not be dropped nor should heavy objects
be placed on top of it.
• Do not expose this instrument to rain and water.
• This instrument has no alarm function. Do not use this instrument if an
alarm function is necessary.
• This instrument is designed for use on adults. When using the instru-
ment on infants or babies, please note that the designed measurement
accuracy cannot be guaranteed.
• Do not use the instrument on a point where there is excessive vibra-
tion. In addition, to avoid excessive impact on the instrument, it should
be handled gently. Failure to observe this may cause breakdown.
• A maximum of 300 hours of measurement data can be stored, or the
maximum storable number of data files is 399 files. If measurements
are continued after the maximum number of storable data has been
reached, the new data will overwrite the oldest data. To keep data, be
sure to download it before the memory becomes full.
• Accurate measurement data may not be obtained in the following
cases.
•
When body movement is excessive
•
When the probe is not attached properly
•
When blood circulation at the measuring point is poor (due to pres-
sure on arm/finger, peripheral circulatory insufficiency)
•
When ambient light (e.g. panel light, fluorescent light, infrared
heat lamp, direct sunlight) is too strong
•
When influenced electromagnetically by other electronic devices (e.g.
near electrical appliances like TV, medial device)
•
When a mobile telephone is used during measurement
•
When influenced by abnormal hemoglobin like carbon monoxide
hemoglobin (HbCO) and methemoglobin
•
When pigments such as cardiogreen, intravascular dyes and indo-
cyanine greenare present in the blood
•
When finger nails are polished
