Please keep the receipt in a safe place.  You may register your

verification purposes, a copy of your dated store receipt must 

still accompany any unit sent in for warranty work.  If the unit is 

returned without a dated store receipt, an out-of-warranty service 

charge applies. 

NOTE: Your warranty period begins at the time of purchase. The 

warranty is validated only by the dated store receipt!  Please

Enjoy your Whistler detector and please drive safely.

Sincerely,
