NUMBER

 

SYSTEM

 for  returned  goods.  If  you have to send any  products to us 

for any reason, please observe the following procedure: 

1.

 

Before you ship us anything, call your salesperson for an RMA number. Please have 
the model and serial number available. 

2.

 

Make sure your product is properly packed so it is not damaged in shipment. 

3.

 

Before you seal the box, write the RMA number on a piece of paper and put it 

inside

 

the box so it’s the first thing we see when we open it. 

4.

 

Also write the RMA number on the 

outside

 of the box, next to the address label. Use 

a black felt-tipped marker. 

5.

 

If  you  contact  us  about  the  returned  item  or  items,  please  refer  to  the  appropriate 
RMA number for quickest service. 

Thank you for your cooperation.
