Anti-counterfeiting Announcement:

The bad and good products is intermingled on market today.Most customers had suffered a lot from the brand replacement products,shell brand products,simulation products,and transferring after-sale service products.To protect your rights,please identify seriously when choose goods.Following is the method to distinguish QUARRZ brand product.

• Method one:Start up,machine will display in sequence:brand,model(such as QUARRZ,AU-300S)
• Method two:After starting up,press ZERO button and B button at the same time,the machine will display in sequence:brand:model,factory number.of which information correspond to the one marked on machine.
• Method three:Check security code that generate automatically by machine number.
