Remote Diagnosis and Resolution
Whenever feasible, Chuyu will first attempt to diagnose and resolve product issues via network, telephone, or other remote support methods. If the issue can be resolved by the user through the installation of specified software updates or replacement parts, Chuyu will guide the user in obtaining and installing them. For component failures that cannot be resolved by the user, Chuyu reserves the right to choose either repair or replacement of the faulty or defective component.

When requesting warranty service, users need to provide the following information:

(2) Relevant hardware and software configuration of the product

(3) System error messages

(4) Detailed description of the fault

(5) User organization, contact person, contact information, and detailed address

5.1 This commitment applies only to hardware failures occurring under normal use within the warranty period.
5.2 Repaired or replaced parts become the property of Chuyu. If the user cannot return the defective part due to data security or confidentiality reasons, the user must purchase the replacement part at their own expense and handle the defective part in a secure and environmentally responsible manner.
