Fast Technical Response
Our engineers identify the cause using photos, short videos and remote testing tools — typically within hours, never days.
Warranty & Support
Warranty Policy
Built for demanding environments. Backed by reliable support that continues long after your equipment ships.
Service throughout the entire lifespan of your product
Support That Continues After Shipment
Our work does not stop when the goods leave our factory. From initial installation guidance, interface configuration and driver integration to on-site troubleshooting, our engineering team supports you for the entire lifetime of the product.
Most issues are resolved remotely through photos, short videos and wiring diagrams — saving you time and avoiding unnecessary returns. When on-site service is required, our engineers will provide a structured plan and a target timeline.
Why customers choose DAVOLIN support
Four Practical Commitments
These are the things our industrial customers say they need most — and they are the four things we promise to deliver.
- Fast Technical Response — Engineering feedback within 24 hours, including weekends for active projects.
- Remote Troubleshooting Assistance — Live guidance via photos, videos and wiring diagrams; most issues resolved without returning the unit.
- Long-Term Product Continuity — Replacement PCBs, firmware updates and spare parts supplied for years-long projects.
- Practical Solutions for Industrial Projects — Real-world engineering judgement, not bureaucratic procedures.
Standard warranty coverage
What’s Covered
DAVOLIN stands behind every unit that ships from our Shenzhen facility.
All DAVOLIN standard keyboards, keypads, trackballs and touchpads carry a one-year limited warranty from the date of shipment. Custom and OEM project terms may vary and are documented in the project quotation.
If a defect covered by this warranty is identified during the warranty period, DAVOLIN will, at its discretion, repair the affected unit, replace it with a functionally equivalent unit, supply replacement components, or issue a corrective solution appropriate to the project scope.
What customers care about most
How We Handle Real Projects
Three principles we apply every time a support case comes in.
Practical Solutions, Not Complicated Procedures
Replacement PCBs, repair instructions, firmware updates, or full replacement units — whichever gets you back online fastest.
Long-Term Product Support
Years-long project continuity for marine, defense and infrastructure installations where the keyboard outlives several equipment generations.
