Unpacking
Remove the AC cord which is packed separately inside the carton. We recommend using only this specially
selected cord for best musical reproduction.
Save your carton and the cardboard inserts for future safe transport in case you move or the unit requires
shipping for repair. Note: the actual printed carton is not itself strong enough for safe shipping: you must
place this carton 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___________________________.
