7 Operating Guide
1) Insert the two batteries in the correct direction, and then replace the cover.
2) Open the clip as shown in Figure 5.
Figure 5 Put finger in position
3)
Put the patient’s finger into the rubber cushions of the clip (make sure the finger is in the right
position), and then clip the finger.
4) Press the button once on front panel.
5) Do not shake the finger and keep the patient at ease during the process. It is not recommended for
the patient to be moving.
6) Get the information directly from screen display.
7) The button
has three functions. When the device is power off, pressing the button can turn it
on; when the device is powered on, pressing the button shortly can change direction of the screen;
when the device is powered on, long pressing the button can change brightness of the screen.
Fingernail and the screen should be on the same side.
8 Repairing and Maintenance
Please change the batteries when the low-voltage displayed on the screen.
Please clean the surface of the device before using. Wipe the device with medical alcohol first, and
then let it dry in air or clean it with dry clean fabric.
Use the medical alcohol to disinfect the product after use prevents cross infection the next time it is
used.
Please take out the batteries if the oximeter is not in use for a long period of time.
The best storage environment of the device is - 40ºC to 60ºC ambient temperature and no higher
than 95% relative humidity.
Users are advised to calibrate the device periodically (or according to the calibrating program of
hospital). It also can be performed by the state-appointed agent or just 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 life span of the device, or even damage it.
9 Troubleshooting
Trouble
Possible Reason
Solution
The SpO
2
and
Pulse Rate cannot
be displayed
normally
1. The finger is not properly
positioned.
2. The patient’s SpO
2
is too low to
be detected.
1. Place the finger properly and try
again.
2. Try again; Go to a hospital for a
diagnosis if you are sure the device
works correctly.
The SpO
2
and
Pulse Rate are not
displayed stably
1. The finger is not placed inside
deep enough.
2. The finger is shaking or the
patient is moving.
1. Place the finger properly and try
again.
2. Keep the patient calm and at rest.
The device cannot
be turned on
1. The batteries are dead or
almost dead.
2. The batteries are not inserted
properly.
3. The device is defective.
1. Change batteries.
2. Reinstall batteries.
3. Please contact the local service
center.
The display is off
suddenly
1. The device will power off
automatically when it gets no
signal within 5 seconds.
2. The batteries are almost dead.
1. Normal.
2. Change batteries.
