Apex N.V. 

(“Apex”) warrants you, the original purchaser, or any party that purchases the device from you, 

that its products are free from defects in material and workmanship under normal use for a period of two 

(2) years from the date of original purchase.  The date of purchase is the date which appears on the first 

invoice or any other proof of purchase provided by an Apex approved dealer.

Subject to the conditions and limitations set forth below, Apex will, at its discretion, either repair or replace 

any part of its products that prove to be defective, provided that the product is returned with proof of 

purchase, shipping prepaid, to an authorised Apex approved service facility.  

Warranty cover of any repairs will only extend to the end of the original warranty period. 

We will be happy to provide you with a list of authorised dealers to whom you can return the defective unit 

or who will give you a returns note to enable you to send the unit to the factory.

Service turn-around time will be as fast as reasonably possible. If you are not satisfied with the repair, 

contact Apex.
