10.     GENERAL TERMS

TEST EQUIPMENT PROVIDED BY THE CUSTOMER

The customer will be responsible for providing all software and hardware, spare parts, documentation and on-site support in order to assure the normal operation of the test stations if those are supplied by the customer. The customer will provide a Test Procedure to calibrate the test stations in order to guarantee that the units tested are good ones. The customer will be required to release the software specifications and troubleshooting guide in time for test development and production. Test equipment will be installed and ready for the pre-production stage. Test equipment will be designed and installed in accordance with appropriate European Directives. ELCAN requires support of a test engineer during pre-production and production. During pre-production ELCAN will carry out an evaluation on the test equipment (Gage Reproducibility and Repeatability evaluation, GRR). ELCAN will inform the customer on the GRR results. In case Test equipment does not pass the GRR evaluation The customer will provide the necessary support to upgrade the test equipment. Test stations will provide bar code reading so test results are linked to every board in a database. Final test station should provide an option for printing a label after a successful test. Only labels of passed unit will be printed.

WARRANTY

ELCAN warrants these products for a period of one year from manufacturing date by ELCAN, and only for workmanship failures. Warranty covers the cost of goods sold by ELCAN. Raytheon’s liability for the articles shall be limited to replacing or repairing the defective articles(s) or at Raytheon’s option refunding the amount paid under this order for such defective articles returned to Raytheon’s factory within 12 months after manufacturing date. This warranty is in lieu of all other warranties expressed or implied, and Raytheon disclaims any warranties of merchantability or fitness for a particular purpose. If the customer wants to reject units found faulty by the standards outlined in the Quality terms, it must be done according to ELCAN procedures for Customer Complaints. This procedure expedites customer complaints and the implementation of corrective actions and also avoids any misunderstanding between both companies:

If customer has a complaint or wishes to return material, the customer will send a non-conformance report to Raytheon giving as much information as possible. Then ELCAN will take the necessary action to process the complaint.

Once approval is given for the customer to return material, ELCAN will contact customer and will provide a RMA (Return Material Authorization) number and will indicate the details and transport agency. Customer should use the RMA on all their packing labels and correspondence with us.

Once the authorized return material is received, ELCAN will analyze the returned material and will send a report to the customer with detailed information (root cause, corrective actions, liability, conclusions debit note acceptance, etc.) related to the results of the analysis.

ELCAN will accept charges of transport agency and liability for the reject units once the faulty unit(s) has been analyzed and determined to be a faulty unit per the mutual agreed terms and conditions between ELCAN and the customer.

Raytheon will not accept any debit note that does not fulfill the previous points and also for:

Cost of material and cost of process performed by the customer on non-conforming units

Transport agency cost in case of returning material previously not accepted by Raytheon.

In order to operate the system efficiently, ELCAN cannot accept any unauthorized material that does not have a RMA number. In case of authorized returns, the issuing of the RMA is not to be construed as an admission of liability by ELCAN. Liability can only be accepted after a detailed analysis of the returned material.
