unpacking
Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier
immediately. Only the consignee may institute a claim with the carrier for damage
incurred during shipping. Be sure to save the carton and all packing materials. Should
you ever need to ship the unit back to Crest Performance, one of its offices, service
centers or the supplier, use only the original factory packing. If the shipping carton is
unavailable, contact Crest to obtain a replacement.
