    The warranty period begins on the day the SeaBat System is accepted by the customer. The system must be serviced by the RESON office which sold the sys- tem. The customer shall prepay shipping charges (and shall pay all duty and taxes) for products returned for service.

  • Page 32: Service And Assistance

    NOTE Before returning any equipment for service, you will need to follow the RESON return procedure: 1. Contact a RESON office to obtain an approved Return Material Authorization (RMA) number. 2. Pack the equipment in the original shipping containers.
