WARRANTY 

 

ORTEC*  warrants  that  the  items  will  be  delivered  free  from  defects  in  material  or  workmanship.  ORTEC  makes  no  other 
warranties,  express  or  implied,  and  specifically  NO  WARRANTY  OF  MERCHANTABILITY  OR  FITNESS  FOR  A  PARTICULAR 
PURPOSE. 

ORTEC’s  exclusive  liability  is  limited  to  repairing  or  replacing  at  ORTEC’s  option,  items  found  by  ORTEC  to  be  defective  in 
workmanship  or  materials  within  one  year  from  the  date  of  delivery.  ORTEC’s  liability  on  any  claim  of  any  kind,  including 
negligence,  loss,  or  damages  arising  out  of,  connected  with,  or  from  the  performance  or  breach  thereof,  or  from  the 
manufacture, sale, delivery, resale, repair, or use of any item or services covered by this agreement or purchase order, shall 
in no case exceed the price allocable to the item or service furnished or any part thereof that gives rise to the claim. In the 
event ORTEC fails to manufacture or deliver items called for in this agreement or purchase order, ORTEC’s exclusive liability 
and buyer’s exclusive remedy shall be release of the buyer from the obligation to pay the purchase price. In no event shall 
ORTEC be liable for special or consequential damages. 

 

Quality Control

 

Before being approved for shipment, each ORTEC instrument must pass a stringent set of quality control tests designed to 
expose any flaws in materials or workmanship. Permanent records of these tests are maintained for use in warranty repair 
and as a source of statistical information for design improvements. 

 

Repair Service

 

If it becomes necessary to return this instrument for repair, it is essential that Customer Services be contacted in advance of 
its  return  so  that  a  Return  Authorization  Number  can  be  assigned  to  the  unit.  Also,  ORTEC  must  be  informed,  either  in 
writing,  by  telephone  [(865)  482-4411]  or  by  facsimile  transmission  [(865)  483-2133],  of  the  nature  of  the  fault  of  the 
instrument being returned and of the model, serial, and revision (“Rev” on rear panel) numbers. Failure to do so may cause 
unnecessary delays in getting the unit repaired. The ORTEC standard procedure requires that instruments returned for repair 
pass the same quality control tests that are used for new-production instruments. Instruments that are returned should be 
packed so that they will withstand normal transit handling and must be shipped PREPAID via Air Parcel Post or United Parcel 
Service to the designated ORTEC repair center. The address label and the package should include the Return Authorization 
Number assigned. Instruments being returned that are damaged in transit due to inadequate packing will be repaired at the 
sender's  expense,  and  it  will  be  the  sender's  responsibility  to  make  claim  with  the  shipper.  Instruments  not  in  warranty 
should follow the same procedure and ORTEC will provide a quotation. 

 

Damage in Transit

 

Shipments should be examined immediately upon receipt for evidence of external or concealed damage. The carrier making 
delivery  should  be  notified  immediately  of  any  such  damage,  since  the  carrier  is  normally  liable  for  damage  in  shipment. 
Packing  materials,  waybills,  and  other  such  documentation  should  be  preserved  in  order  to  establish  claims.  After  such 
notification to the carrier, please notify ORTEC of the circumstances so that assistance can be provided in making damage 
claims and in providing replacement equipment, if necessary.
