Technical Support

Warranty coverage is determined by product terms, project contract and actual fault cause. External damage, construction damage, water ingress from a cracked housing, abnormal use, conditions beyond spec or consumable items may fall outside standard warranty; actual handling follows inspection results and contract terms.

First confirm whether internal electronics, battery, contacts and the sealing structure are damp, corroded or damaged. If the cracked housing has already broken the seal, replacing only the housing may not restore long-term stability; whether it can be repaired or needs full replacement follows inspection results and product structure.

Provide product model, device serial number, installation position, on-site photos or video, platform screenshots, time of occurrence, SIM or network info, recent construction or maintenance records, and whether the issue is reproducible. After receiving the information, NHR will perform initial assessment, inspection and follow-up handling per the project or RMA process.

If the device is exposed, cracked, has a pressured battery or may affect personnel or road safety, cordon off or protect the site first to avoid touch, water ingress, continued loading or self-disassembly. The project contact or operations team should then contact NHR to judge power-off, removal, inspection or replacement based on device condition.

Samples, PoC, MOQ and lead time are affected by product model, stock, quantity, connectivity version, customization, certification and component supply. Provide the test purpose, estimated quantity, deployment country, required date and customization needs, and the sales contact will provide a formal assessment.
