1. This data is only generated by the testing sample provided by the customer and does not represent the final mass production status of the customer;
2. Customers are requested to carefully confirm the matching circuit modification and environmental treatment instructions in our report;
3. Before mass production, please provide a trial production sample to us for secondary verification; if there is any replacement of materials, software updates, environmental treatment, etc., please inform us in advance;
4. If the customer needs a third-party retest, or sends it to the customer for testing, please go to our company for verification before sending the sample; to prevent differences between the machine and the debugging machine;
5: Our company does not accept machine data other than our debugging and data from other darkroom tests, but it can be used as a reference, except for certified darkrooms. If there is a discrepancy in the data, the debugging machine shall prevail to find the reason. Shenzhen Qianmu Communication Technology Co.,Ltd.
