Helpful Answers
Frequently Asked Questions
Does every product have the same warranty period?
No. Product category, model, sale terms and supplied documentation determine the applicable duration and scope.
Does registration guarantee that every failure is covered?
No. Registration records the product and purchase. Coverage still depends on the cause, conditions and applicable warranty terms.
Can a dealer promise a different warranty?
Only written terms issued or formally accepted by STH should be relied upon. Ask for clarification before purchase.
Who pays transport or inspection costs?
This depends on the applicable policy, claim outcome, product and location. Confirm before sending a product.
