    Upon receipt, inspect the vender for shipping damage. If there is any damage, have the driver note the damage on the Bill of Lading and notify Dixie-Narco. Although the terms of the vender sale require that the consignee originate shipping damage claims, Dixie-Narco will gladly help if you must file a claim.

If such accessories are to be used, check with either Dixie-Narco or the accessory manufacturer about physical and electrical compatibility before attempting to interface such accessories to the SIID vender.
