Unpacking

Save your carton and the styrafoam inserts for future safe transportation in case you move or the unit ever
requires shipping for repair. Note, the actual printed carton is not itself strong enough for safe shipping, so
you must place it into an additional outer 'overcarton' before shipment.

Before you proceed, find the serial number which is located on the rear panel of the unit and note it here for
future reference or in case the unit is ever stolen ____________________.
