The warranty terms issued by our authorised

when your dealer has completed the reply 
card accompanying the sale of the unit, has 
stamped and signed it and you have then 
sent the reply card to the marketing 
company in your country.

Should you wish to call upon the guarantee, 
please apply to your dealer or nearest 
authorised Customer Service centre taking
