• This instrument should be used in areas with an ambient temperature of 0 to
40°C (32 to 104°F) and a relative humidity of 30 to 95%, with no condensation.
• This is a precision instrument. To avoid the possibility of it being damaged,
the instrument should not be dropped nor should heavy objects be placed
on top of it.
• This instrument conforms to water-seal rating of IPX4 (IEC 60529), which
ensures that the instrument will show no adverse damage even if exposed
to water splashing from any direction. However, the instrument is not water-

should objects be placed on top of it.
• The accuracy of this instrument, like that of all other dual-wavelength
oximeters, can be influenced by the presence of abnormal hemoglobins such
as carboxyhemoglobin (HbCO) and methemoglobin. Tables 1 and 2 below
show the errors which may occur due to these hemoglobins. The instrument
may also be affected by cardiogreen or intravascular dyes.
• Do not use a mobile telephone when using this instrument. Doing so may
result in measurement error.
• This instrument may interfere with magnetic resonance imaging (MRI)
procedure.
• The disposal method of AAA batteries varies according to local government
