Beurer BM 57 Mode D'emploi page 36

If the buyer wishes to make a warranty claim, they should
approach their local retailer in the first instance: see the
attached "International Service" list of service addresses.
The buyer will then receive further information about the
processing of the warranty claim, e.g. where they can send the
product and what documentation is required.
A warranty claim shall only be considered if the buyer can
provide Beurer, or an authorised Beurer partner, with
– a copy of the invoice/purchase receipt, and
– the original product.
The following are explicitly excluded from this warranty:
– deterioration due to normal use or consumption of the
product;
– accessories supplied with this product which are worn out
or used up through proper use (e.g. batteries, rechargeable
batteries, cuffs, seals, electrodes, light sources, attach-
ments and nebuliser accessories);
– products that are used, cleaned, stored or maintained
improperly and/or contrary to the provisions of the instruc-
tions for use, as well as products that have been opened,
repaired or modified by the buyer or by a service centre not
authorised by Beurer;
– damage that arises during transport between manufacturer
and customer, or between service centre and customer;
– products purchased as seconds or as used goods;
– consequential damage arising from a fault in this product
(however, in this case, claims may exist arising from
product liability or other compulsory statutory liability
provisions).
Repairs or an exchange in full do not extend the warranty
period under any circumstances.
