7.2 Open the clip as shown in Figure 5.
7.3 Let the patient’s finger put into the rubber cushions of the clip (make sure the finger
is in the right position), and then clip the finger.
7.4 Press the switch button once on front panel.
7.5 Do not shake the finger and keep the patient at ease during the process.
Meanwhile, human body is not recommended in movement status.
7.6 Get the information directly from screen display.
7.7 In boot-strap state,press button ,and the device is reset.
Fingernails and the luminescent tube 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 by dry clean fabric.
• Using the medical alcohol to disinfect the product after use, prevent from cross
infection for next time use.
• Please take out the batteries if the oximeter is not 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 hospital). It also can be performed at 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 useful life of the device, or even damage it.
9 Troubleshooting

11 Function Specification
Trouble
Possible Reason
Solution
The SpO
2
and Pulse Rate
can not 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 all right.
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. Let the patient keep
calm.
The device can not be
turned on.
1. The batteries are
drained or almost drained.
2. The batteries are not
inserted properly.
3. The malfunction of the
device.
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
drained.
1. Normal.
2. Change batteries.
