FAQ

While our products come with both paper and electronic installation and operation manuals, we also provide detailed photos and videos for easier understanding. For customized products, we provide a technical specification sheet tailored to your needs for confirmation.

2) User Training
Before receiving the product, our installation engineers will be trained in detail, providing guidance on the installation manual. Remote training via video and photos will also be conducted, providing detailed explanations of parameter settings and functions.

3) Warranty Service​
During the warranty period, the replacement of specific defective parts is free of charge under normal operation. However, ​if a malfunction or defect is caused by user improper operation, an additional fee may apply.​

​5) Returns/Replacements​

Given that our products feature ​exceptionally simple installation processes, we ​typically do not dispatch engineers to customer sites.

Additionally, please be advised that ​visa approvals remain an unpredictable factor.
