6) Resistance to Surrounding Light: The deviation between the value measured in the condition of man-made light
or indoor natural light and that of darkroom is less than ±1%.
7) It is equipped with a function switch. The Oximeter can be powered off in case no finger is in the Oximeter within
5 seconds.

7 Operating Guide
1) Insert the batteries then replace the cover.
2) Open the clip as shown in Figure 5.
Figure 5 Put finger in position
3) Insert the patient's finger into the rubber cushions of the clip and clip the finger (make sure the finger is in the
right position).
4) Press the button on the front panel.
5) Do not shake the finger. Keep the patient still and at ease during the process.
6) The information will be displayed on the screen.
7) The button has three functions.When the device is powered off, pressing the button will turn it on; when
the device is powered on, pressing the button shortly can change direction of the screen; pressing the button for
longer while the device is powered on will change the brightness of the screen.
8) Changing the display direction: When the device is powered on and is on the finger showing the SPO2 and
pulse rate result you can simply change the display direction. If you press the start button once you can remove the
pulse graph from display and that makes the display numbers larger. By each press then you can rotate the display
vertically and horizontally.
Fingernails and the luminescent tube should be on the same side.
8 Maintenance and Repair
 Change the batteries when the low-battery indicator is displayed on the screen.
 Clean the surface of the device before use. Wipe the device with medical alcohol and let it dry in air. Otherwise,
clean it using a clean, dry fabric.
 Use medical alcohol to disinfect the device after use so as to prevent cross infection during the next use.
 Remove the batteries if the Oximeter will not be in use for a long time.
 The best storage environment of the device is -40ºC to 60ºC ambient temperature and not higher than 95%
relative humidity.
 Users are advised to calibrate the device termly (or according to the calibrating program of the hospital). It also
can be performed at the state-appointed agent or you can contact us for calibration.
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 useful
life of the device, or even damage it.
