1.Guidance
The purpose of this document is to help OPPO levels 1 and 2 maintenance technicians to carry out service to OPPO products. This Service Manual is to be used only by authorized OPPO maintenance service centers, and the content is confidential. Please note that OPPO provides also other guidance documents (e.g. Technical Service Bulletins) for maintenance service cooperative corporations, therefore, please follow the guidance regularly and comply with the given instructions. While every endeavor has been made to ensure the accuracy of this document, some errors may exist. Please keep in mind also that this documentation is continuously being updated and modified, please keep watching out for the newest version.
1.1 Warnings and Cautions
Please refer to the handset's user guide for instructions relating to operation, service and maintenance including important safety information. Note also the following:
Warnings:
1)Service centers may be required to install the handset's vehicle-mounted system in vehicles. Under certain fault conditions, the handset's RF signals may affect the operation of the vehicles' electric power management systems and anti–skid braking systems (ABSs). If necessary, consult the vehicle dealer/manufacturer to determine the immunity of vehicle electronic systems to RF energy.
2) The handset must not be operated in areas likely to contain potentially explosive atmospheres, such as petrol stations, gas stations and blasting areas.
3) Operation of any radio transmitting equipment, including handsets, may interfere with the functionality of the medical devices protected by industrial mechanisms. Consult the manufacturer of the medical device if necessary. Other electronic equipment may also be subject to interference.
1.2 Attention
1) Maintenance and calibration must be undertaken by qualified technicians only.
2) Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn.
3) Use only approved materials as specified in the bill of materials (BOM) list.
4) Ensure all components, screws and insulators are correctly re-fitted after maintenance and calibration. Ensure all cables and wires are repositioned correctly.
Electrostatic discharge can easily damage the sensitive components of electronic products. Therefore, every service center has to take care of OPPO's ESD protection requirements. Also see ESD Protection Requirements in this Service Manual
2. General Repair Information
※In this section the technician will get some general hints to carry out repairs:
Customer service personnel can download and read product documentation on：Download and read the product guide or user manual.
Before starting the repair, you must enter the ESD Protected Area and connect your wristband. Use gloves to avoid corrosion and fingerprints. Protect windows and display screens with a film to avoid dust and scratches. When cleaning the metal pads, you have to use a soft cloth/ESD brush and isopropanol. It is not allowed to use an eraser because it scratches the surface and will lead later on to oxidation and corrosion. Mechanical parts (except shielding covers and bent parts), which cannot be repaired in the event of a failure, can only be replaced, if they are not soldered. After removing and maintaining the shielding covers, make sure to replace them with new ones. Otherwise, the high-frequency leakage can have an influence on the device. Always use original OPPO spare parts. Check the soldering joints of the parts, which are concerned regarding the indicated error (e.g. soldered connectors or switches) and re-solder them if necessary (only repair centers that can conduct lead-free soldering). Remove redundant soldering flux after soldering. Assemble the handset with the standard screw torque (see the Introduction of the Service Manual).
Always use your own equipment for testing where you are sure that it works. For complaints about charger function, please test the handset with your own charger to be sure if the handset or charger causes the malfunction. When doing the fault log entries, always note the fault code which caused the malfunction. The accuracy of this code will be a great help to quality improvement. （Please refer to the relevant files if necessary）.
