obtain an RMA number and shipping instructions prior to shipment. This number must be clearly
displayed on the exterior of the shipping carton.
Only parcels displaying an RMA number will be accepted. In Washington state, call
425-743 3171. Huntron is also accessible bye FAX at 425-743-1360, by e-mail at
