Warranty and Service Policy

Last updated: August 3, 2026.

Warranty period

The commercial warranty period and covered components are stated in the written quote, invoice, product specification or warranty document for the specific order. The website does not promise a default product-specific period where that period has not been confirmed in the order. Consumables and normal-wear items are covered only when the failure results from a manufacturing defect or applicable law requires a remedy.

Coverage

The commercial warranty covers manufacturing defects under normal use and compliance with the manual. Depending on diagnosis, we may provide remote troubleshooting, replacement parts, repair, replacement or another agreed remedy. We may reasonably request photos, video, diagnostic results or remote access arranged with your informed permission.

Exclusions

Coverage does not apply to damage caused by accident, misuse, unsafe operation, liquid, incorrect voltage, unauthorized modification or repair, or ordinary wear, where that cause is related to the reported failure.

Service request

Email support@dzentech.store with the order/serial number, model, date of failure and evidence of the issue. Do not return equipment before receiving instructions. This commercial warranty is in addition to any non-waivable statutory warranty or consumer remedy.
