only by qualified service technicians. Users
are not permitted to maintain it by
themselves.
The oximeter cannot be used together with
devices not specified in User Manual.
Cautions
Explosive hazard—DO NOT use the oximeter
in environment with inflammable gas such as
some ignitable anesthetic agents.
DO NOT use the oximeter while the testee is
under MRI or CT scanning.

Warnings
An uncomfortable or painful feeling may
appear if using the oximeter continuously on
the same place for a long time, especially for
poor microcirculation patients. It is
recommended that the oximeter should not be
applied to the same location for longer than 2
hours. If any abnormal condition is found,
please change the position of oximeter.
DO NOT clip this device on edema or tender
tissue. 0 The light (the infrared light is
invisible) emitted from the device is harmful
to the eyes, so service technician or testee
should not stare at the light.
The local law must be followed when
disposing of the device.
Attentions
Keep the oximeter away from dust, vibration,
corrosive substances, explosive materials, high
temperature and moisture.
The device should be kept out of the reach of
children.

If the oximeter gets wet, please stop using it
and do not resume operation until it is dry.
When it is carried from a cold environment to
a warm and humid environment, please do not
use it immediately.
DO NOT operate the button on the front panel
with sharp materials.
DO NOT use high temperature or high
pressure steam disinfection on the oximeter.
Refer to Chapter 9 for instructions of cleaning
and disinfection.

1.4 Applications and Scope
Fingertip Oximeter is intended for measuring
the pulse rate and functional oxygen
saturation (SpO2) through the testee’s body
especially on finger. It is designed by using
internal (build-in) sensor and applicable for
spot-check during no motion and well
perfusion condition and can be used in
homes, hospitals and clinics. The device is
used for adult.

5 Instructions for Operation
•The finger should be put in properly and
correctly.
•Do not shake the finger. Keep at ease 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.
•Vigorous exercise and electrosurgical
device interference may affect the
measuring accuracy.
•The orientation-sensor works on the basis of
the gravity. A small movable metal ball is
built in the orientation-sensor for detecting
the orientation of the oximeter. When you
want to change the oximeter’s display
direction, if you move the oximeter too
slowly, the movable metal ball will also
move slowly because of not enough
acceleration. Consequently the response of

Fingertip Pulse Oximeter
- 7 -
orientation detection would be delayed.
Please move the oximeter with a bit of force
if you want to change the display
direction(such as bend/extend your finger
quickly), so an acceleration is provided to
the orientation-sensor for quick sensing the
orientation change.
•Using enamel or other makeup on the nail
may affect the accuracy of measurement.

•Please take out the batteries if the oximeter
will not be used for a long time.
•The best storage environment of the device
is -25ºC to 70ºC ambient temperature and
less than 93% relative humidity.
•The oximeter is calibrated in the factory
before sale, there is no need to calibrate it
during its life cycle. However, if it is
necessary to verify its accuracy routinely,
the user can do the verification by means of
SpO2 simulator, or it can be done by the
local third party test house.
High-pressure sterilization cannot be
used on the device.
Do not immerse the device in liquid.
It is recommended that the device should
be kept in a dry environment. Humidity
may reduce the life of the device, or even
damage it.
8.2 Cleaning and Disinfecting Instruction
•Surface-clean sensor with a soft cloth by
wetting with a solution such as 75%
isopropyl alcohol, if low-level disinfection

Fingertip Pulse Oximeter

is required, use a 1:10 bleach solution.
•Then surface-clean with a cloth saturated
with clean water and dry with a clean, soft
cloth. Caution: Do not sterilize by
irradiation steam, or ethylene oxide. Do not
use the sensor if it is damaged.
