which include important safety information. 

 

Servicing and alignment must be undertaken by qualified personnel only. 

 

Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is 

worn. 

 

Use only approved components as specified in the parts list. 

 

Ensure all components, modules, screws, and insulators are correctly re-fitted after servicing and 

alignment 

 

Ensure all cables and wires are repositioned correctly electrostatic discharge can easily damage 

the sensitive components of electronic products. Therefore, every service supplier must observe the

GENERAL REPAIR INFORMATION 

 

Make sure your testing equipment is functioning properly before beginning repair work. 

 

Before starting repairs you must observe ESD precautions such as being in your ESD protected 

area and connecting your wristband. 

 

Use gloves to avoid corrosion and fingerprints. 

 

Cover windows and displays with a protective film to avoid dust and scratches. 

 

Use a lint-free cloth to clean the LCD. 

 

When cleaning the pads use a soft cloth\ESD brush and isopropanol. Do not use a glass fiber 

pencil: this scratches the surface and will corrosion. 

 

Non-faulty mechanical parts(except shielding lids and bent parts or soldered components).May be 

reused if they are not soldered. 

 

When removing the shielding lids make sure to replace them with new ones, otherwise the 

high-frequency leakage can affect the device. 

 

Always use the original spare parts. 

 

10 

Check the soldering joints of the parts concerned with regard to the fault symptom. And resolder 

them if necessary.

 

11 

Remove excess soldering flux after repair. 

 

12 

Observe the torque requirements when assembling the unit. 

 

13 

Please aware that some malfunctions may be software related and solved by an update
