Since its foundation in 1972, Velleman® acquired extensive experience in the electronics world and currently 
distributes its products in over 85 countries. 
All our products fulfil strict quality requirements and legal stipulations in the EU. In order to ensure the quality, 
our products regularly go through an extra quality check, both by an internal quality department and by 
specialized external organisations. If, all precautionary measures notwithstanding, problems should occur, 
please make appeal to our warranty (see guarantee conditions). 

General Warranty Conditions Concerning Consumer Products

• All consumer products are subject to a 24-month warranty on production flaws and defective material as from 
the original date of purchase. 
• Velleman® can decide to replace an article with an equivalent article, or to refund the retail value totally or 
partially when the complaint is valid and a free repair or replacement of the article is impossible, or if the 
expenses are out of proportion. 
You will be delivered a replacing article or a refund at the value of 100% of the purchase price in case of a flaw 
occurred in the first year after the date of purchase and delivery, or a replacing article at 50% of the purchase 
price or a refund at the value of 50% of the retail value in case of a flaw occurred in the second year after the 
date of purchase and delivery. 

• Not covered by warranty: 

- all direct or indirect damage caused after delivery to the article (e.g. by oxidation, shocks, falls, dust, dirt, 
humidity...), and by the article, as well as its contents (e.g. data loss), compensation for loss of profits; 
- consumable goods, parts or accessories that are subject to an aging process during normal use, such as 
batteries (rechargeable, non-rechargeable, built-in or replaceable), lamps, rubber parts, drive belts... 
(unlimited list); 
- flaws resulting from fire, water damage, lightning, accident, natural disaster, etc.…; 
- flaws caused deliberately, negligently or resulting from improper handling, negligent maintenance, abusive 
use or use contrary to the manufacturer’s instructions; 
- damage caused by a commercial, professional or collective use of the article (the warranty validity will be

- damage resulting from an inappropriate packing and shipping of the article; 
- all damage caused by modification, repair or alteration performed by a third party without written permission 
by Velleman®. 
• Articles to be repaired must be delivered to your Velleman® dealer, solidly packed (preferably in the original 
packaging), and be completed with the original receipt of purchase and a clear flaw description. 
• Hint: In order to save on cost and time, please reread the manual and check if the flaw is caused by obvious 
causes prior to presenting the article for repair. Note that returning a non-defective article can also involve 
handling costs. 
• Repairs occurring after warranty expiration are subject to shipping costs.
