1.1 warnings and Cautions
1.1.1 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.
1.1.2 Cautions
1. Maintenance and calibration must be undertaken by qualified technicians only.
2. Use only the materials listed in the BOM for maintenance services.
3. All parts are assembled correctly as required.
4. Electrostatic discharge can easily damage the sensitive components of electronic products. Service centers must follow with OPPO's requirements for electrostatic protection. All the operations must be on an ESD maintenance table and worn with an ESD ring.
2. General Repair Information
1．Before starting the maintenance, please enter the ESD area and wear the ESD ring.
2. ESD gloves are recommended to avoid oil stains and fingerprints. 
3. Use protective film to protect the display screen, camera, and camera lenses from dust and scratches.
4. It is necessary to use dust-free cloth, ESD brush and alcohol (concentration above 95%) for appearance cleaning. Do not use other items for cleaning (like eraser) to prevent the protective layer on the scratched surface from oxidizing and corroding.
5. It can only be replaced instead of repair if the welded mechanical parts (except the shield cover and shield frame parts) fail.
6. Repairs must be made using the accessories supplied by OPPO.
7. Check the contacts or solder joints of devices that may cause simple faults (e.g. soldered connectors or switches) and re-solder them if necessary (only repair centers that can conduct lead-free soldering) and clean the residual flux after welding.
8. You must use the equipment provided by OPPO to test whether the mobile phone is normal. For example, if the customer feedback charging malfunction, please use the original adapter of OPPO to test to ensure the accuracy of test results.
9. When recording the fault code in the after-sales system, fill in the fault phenomenon code and fault reason code according to the actual situation, and accurately record the replacement accessory code (refer to " Smart Phone Fault Reason Code List " if necessary).

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 “Pass” with the calibration completed. 

Precautions：
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.
2. Re-calibrate the phone for the user once the phone has been disassembled, Otherwise the phone will be with Poor blurred effect issues;
3. If it shows “Fail 69” during calibration, the lens is too far from the chart;
4. If it shows “Fail 70” during calibration, the lens is not parallel to the chart;
5. If it shows “Fail 68” during calibration, the lens is too close from the chart.

8. Cautions
1. Recalibration is required after maintenance.
2. After assembly, calibration must be performed before functional testing to ensure proper function after maintenance;
3. Sensory test items require staff to judge the results. For example, LCD test, vibration test, pre-test, post-test, flash test, echo test, audio test, and call test are all human judgment results. Therefore, the judgment result must be followed. Test requirements judgment;
4. It is forbidden to use the return key to judge the result in advance if the test item is not tested.
