WARRANTY

REER warrants that each AD SR2 unit in new ex-factory condition, in
conditions of normal use, is free of defects in the materials and of
manufacturing defects for a period of 12 (twelve) months.
In this period, REER undertakes to eliminate any faults in the product
through repair or replacement of the faulty parts, completely free of
charge as regards material and labor.
However, REER reserves the right to replace the entire faulty appliance
with another equivalent appliance or with the same characteristics
instead of repairing this.
Validity of this warranty is regulated by the following conditions:

  The user must inform REER of the fault within twelve months

from the date of delivery of the product.

  The appliance and its components must be in the conditions

in which they were delivered by REER.

  The serial numbers must be clearly legible.

  The fault or defect has not been caused directly or indirectly

by:

 

Improper use;

 

Non-compliance with instructions for use;

 

Carelessness, inexperience, incorrect maintenance;

 

Repairs, modifications, adaptations not carried out by
REER personnel, tampering, etc.;

 

Accidents or impacts (also due to transportation or
causes of force majeure);

 

Other causes not to be ascribed to REER.

Repairs will be carried out at the REER laboratories to which the material
must be delivered or dispatched: transport risks and the risks of any
damage or loss of the material during shipment are the responsibility of
the user.
All products and components replaced become the property of REER.
REER does not recognize any other warranties or rights except for those
specifically described above; therefore, no claims for damages may be
submitted for expenses, interruption of business or other factors or
circumstances in any way related to failure of the product or of one of its
parts.

Precise, complete compliance with all the rules, instructions and prohibitions indicated in this
handbook is an essential requirement for correct functioning of the safety interface.
REER s.p.a. therefore declines any responsibility for all and anything resulting from failure to
comply, even partially, with such indications.

Characteristics subject to change without  notice. 

 Total or partial reproduction is forbidden without the

prior authorization of REER.
