What is the after-sales service policy?

Our company provides a tiered after-sales service guarantee:

1. Warranty Policy

• Standard products come with a free warranty of 1 year (subject to the contract)
• Free repairs or replacements are provided during the warranty period due to quality issues

2. Technical Service Support

• We offer installation and debugging guidance, system upgrade recommendations
• Remote technical support to answer common questions
• On-site support by technicians can be arranged for major projects

3. Repair Time

• Repaired equipment undergoes strict aging tests
• Repair times are generally 2–3 working days (excluding transportation time)
• Commercial customers can negotiate backup machine services

Note: Unauthorized use or damage will result in charges for parts and labor; tearing off the anti-disassembly label on the product will affect the warranty.
