1.1 Guidance Overviewļ¼
The purpose of this document is to help OPPO level1 and level 2 maintenance engineers to carry out service to OPPO products. This Service Manual is to be used only by authorized OPPO maintenance service centers, and the content shall be keep in confidential. Please note that OPPO provides also other guidance documents (e.g. Technical Service Bulletins) for maintenance service cooperative corporations, therefore, please follow these regularly and comply with the given instructions. While every endeavor has been made to ensure the accuracy of this document, some errors may exist. If you find any error or if you can offer further suggestions, please notify OPPO by using the address below: zhouyangguang@oppo.com. Please keep in mind also that this document is continuously being updated and modified, please keep watching out for the newest version.
1.2. Warnings and Cautions:
Please refer to the phone's user guide for instructions relating to operation, service and maintenance including important safety information. Note the following:
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 antiāskid braking systems (ABSs). If necessary, consult the 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 devices if necessary. Other electronic equipment may also be subject to interference.
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 onļ¼Download and read the product guide or user manual on the site: ftp://ļ¼ftp://wxfuwu@172. 16. 103. 212:919
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 solution. 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. Also, fill in the replaced part, if needed.
Many service documents are available on the FTP server: ftp://wxfuwu@172. 16. 103. 212:919, which will be notified via email. Please note that the documents shall be updated in time.

7.Calibration:
Calibration Path : input *#899# in the dialing interface > Aftersale calibration/ last test in the automatic test ; When the following interface pops up, take a photo with the chart.
Note: Please align the yellow box with the edge of the chart, and then take a Photo. Then, do not operate the phone when the phone enters the computing interface until it display āPassā with the calibration completed.

Precautionsļ¼
1. If the phone sent to the SC is with Poor blurred effect issues in the Portrait Mode, re-calibrate the camera for the user.

9.Precautions
| ITEM | Disassemble and Assemble Precautions | Fault phenomenon |
|---|---|---|
| 1 | Stepper motor FPC needs to be assembled under the motor | Poor camera lift |
| 2 | Assembly Stepper motor can not press the solder joint position | FPC damage ļ¼and the motor not work |
| 3 | When installing the front camera BTB, pay attention to the fact that the male and female seats are aligned and then gently buckled down. | front camera not open |
| 4 | Disassemble the machine to pay attention to whether the speaker foam is damaged or layered, if layered need to be replaced | Speaker noise |
| 5 | When disassembling the bottom cover, first remove the front BTB bracket, then remove the front camera BTB, careful Front FPC cannot bend and finally disassemble the lower cover. | front camera not open |
| 6 | The light guide column is affected by alcohol. Note that the light guide column canāt have large amount of alcohol. | Abnormal light perception |
| 7 | Do not use alcohol to wipe the front transparent cover; (When there is dirt, use only dry and clean cloth to wipe clean) | Prevent cracking of the cover or failure after repair (acrylic material is not alcohol resistant) |
