On the basis of cleaning, disinfection treatment should be carried out when necessary. 

The main unit and the power box should be cleaned with ethanol-based or acetaldehyde-based cleaning agents. 

The reusable SpO2 probe should be cleaned with ethanol-based or acetaldehyde-based cleaning agents. 

Explanation: 

Ethyl group: Ethanol 70%; 

Acetaldehyde group: Formaldehyde (35 - 37%) 

Do not allow the disinfectant solution to enter or come into contact with the machine or its components; 

Make sure to remove any traces of the disinfectant from all surfaces.

Washing should be done using soft cloths. 

The main unit and the power supply can be made of materials containing soap, amino or ethanol groups. 

The reusable SpO2 probe should be made of materials containing soap, amino, and alcohol groups. 

Explanation: 

Ammonia solution: Diluted ammonia solution < 3%; Ethanol: 70% ethanol, 70% isopropanol; 

Do not use abrasive materials such as steel wire brushes or silver polishing agents; 

Do not allow the cleaning solution to enter the machine or soak the components to be cleaned.

The subject needs to remain quiet; place the blood oxygen probe at the appropriate position on the patient's finger, and the probe cable should be placed on the back of the hand (with the nail surface facing upwards); continuous monitoring of the same area for a long time is not allowed; do not use the blood oxygen probe and the blood pressure cuff on the same arm; dirt on the finger or nail polish on the nail surface can also affect the measurement data; try to avoid direct exposure of the blood oxygen probe to strong external light. 

When an alarm occurs, please try to restart the machine; if the problem persists after restarting, please contact the after-sales service for repair immediately. Do not attempt to disassemble the machine for inspection on your own.

When attaching the disposable electroencephalogram sensor, ensure that the patient's forehead has been disinfected with alcohol and that the attachment position is correct; during use, fix the module.

There are factory return for repair, remote assistance for software upgrade, and on-site repairs for customer-specific requirements.

The whole machine is guaranteed for two years, the accessories for six months, the BIS module for one year. Damage caused by human factors is not covered by the warranty; the designed service life is five years.
