A：This failure is belong to insertion tube yellow crystallization. If customers don’t use enzymatic detergent to soak the insertion tube and decompose the protein before disinfection, the chemical reactions between proteins and organic disinfectants would lead the color change.

A：Disinfection and sterilization are essential for ensuring that medical equipment do not transmit pathogenic microorganisms to patients. Disinfection describes a process that eliminates many, if not all, pathogenic microorganisms on inanimate objects. Sterilization describes a process that destroys or eliminates all forms of microbial life and is carried out by physical or chemical methods.

A：Gastroscope: 30 KPa

Colonoscope: 30 KPa

Bronchoscope: 20 KPa

A:  Sodium hypochlorite: Not recommended

Low temperature plasma: Not recommended

Peracetic acid: (0.2%-0.35%)  for disinfection≥5min; for sterilization≥10min

The soaking time should be strictly in accordance with the minimum time recommended by the disinfectant manufacturer (remove immediately the disinfection solution when it meets the requirements)

A:  As most of the disinfection solution is harmful to patient and alcohol could completely remove the rest solution and accelerate dry of endoscope.

A:  Not, doing the WB during the first time using is enough, all AOHUA processors provide white balance function.

A: Two types of outline enhancement are available. Structure Enh for observation of larger mucosal structures with high contrast. Edge Enh for observation of smaller structures, such as capillaries.

A: AQ-100, AQ-200;

A: VME-98C, VME-1650C could only work with integrated processor VME-2300HD,

VME-98S and VME-1650S are for VME-2800 HD;

VGT-Q30 and VCL-Q30 are for AQ-100HD.

A: Different life time and color temperature, Xenon lamp features a higher brightness and authenticity of color, also a better performance of CBI function.

A: The processor could also switch on with back up lamp –LED lamp, but the only purpose for back up lamp –LED lamp design is to remove the endoscope from patient after sudden xenon lamp failure   

A: The 4th generation operation handle used ergonomic design.it is lightweight than the 3rd generation. The 4th have four buttons and one more than the 3rd one.

A: 1,Try with the new Air/water valve
     2, Check the sealing ring of water bottle.
  3,Make sure there is enough water in the bottle.
    4, Make sure you already switch on the air pump.

A: 1, Try with the new suction valve

2, Check the connection of suction tube

3, Make sure you already switch on the suction pump.

4, Make sure the biopsy valve is properly attached

A: We suggest the operator to press freeze button at the middle area, because the long-term pressing the button from edge side would damage the opposite side.
