Possible reason


SpO2% or pulse rate can not be shown normally

1. Finger is not plugged correctly

2. Patient’s SpO2value is too low to be measured

1.Retry by plugging the finger

2. There is excessive illumination

3. Measure more times, If you can make sure about no problem existing in the product. Please go to a hospital timely for exact diagnosis

SpO2% or pulse rate is shown unstably

1. Finger might not be plugged deep enough

2. Excessive patient movement

1. Retry by plugging the finger

2. Be calmness.

The Monitor can not be powered on

1.No battery or low power of battery

2.Battery might be installed incorrectly

3. The Monitor might be damaged

1. Please replace battery

2. Please reinstall the battery

3. Please contact with local customer service centre

Indication is suddenly off

1.The Oximeter is automatically powered off  when no signal is detected longer than 8 seconds

2. The batteries power is too low to work

 1. Normal

 2. Replace the battery

“Error3”  or  “Error4” Displayed on screen

1. Err 3 means the red emission LED is damaged.

2. Err 4 means the infra-red emission LED is damaged.

1. Check the red emission LED

2. Check the infra-red emission LED

“Error 6”

Err 6 means the crystal is failure

Change the crystal

“Error7” displayed on screen

Err 7 means all the emission LED or reception dioxide is damaged.

Check the emission LED and reception dioxide.


Guidance and Manufacture’s declaration  - electromagnetic emission

Guidance and Manufacture’s declaration – electromagnetic environment specified below. The customer of the user of the Pulse Oximeter should assure that it is used in such and environment.

Emission test


Electromagnetic Environment – guidance

RF emissions CISPR 11

Group 1

The pulse Oximeter uses RF energy only for very low and is not likely to cause interference in nearby electronic equipment.
