Velleman® Service and Quality
Warranty
Velleman® has over 35 years of experience
in the electronics world and distributes its
products in more than 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 (for
EU):
• 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;
- frequently replaced consumable goods,
parts or accessories such as batteries,
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 reduced to six
(6) months when the article is used
professionally);
- 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.
• The above conditions are without
prejudice to all commercial warranties.
The above enumeration is subject to
modification according to the article
(see article’s manual).

dan 85 landen.
Al onze producten beantwoorden aan strikte
kwaliteitseisen en aan de wettelijke
bepalingen geldig in de EU. Om de kwaliteit
te waarborgen,
ondergaan onze producten op regelmatige
tijdstippen een extra kwaliteitscontrole,

probleem optreden, dan kunt u steeds een
beroep doen op onze waarborg (zie

Algemene waarborgvoorwaarden
consumentengoederen (voor Europese
Unie):
• Op alle consumentengoederen geldt een

de oorspronkelijke aankoopdatum.
• Indien de klacht gegrond is en een gratis
reparatie of vervanging van een artikel
onmogelijk is of indien de kosten hiervoor
buiten verhouding zijn, kan Velleman®
beslissen het desbetreffende artikel te
vervangen door een gelijkwaardig artikel of
de aankoopsom van het artikel gedeeltelijk
of volledig terug te betalen. In dat geval
krijgt u een vervangend product of
