Beurer HS 20 Gebrauchsanweisung Seite 38

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, attachments and nebuliser
accessories);
- products that are used, cleaned, stored or maintained
improperly and/or contrary to the provisions of the
instructions 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;
