Unpacking

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_________________.

    Speaker connections You may use either bare wire or banana plugs with the HCA-800II "5-way" terminals. If you use bare wire without spade lugs or plugs, make sure you strip only enough wire to fit into the hole that runs across the metal shaft of the terminal.

    Speaker A and B Switches Each switch A and B controls one pair of speakers. Do not press either switch while the HCA-800II is operating at high power. Make sure the combined parallel speaker load is above 4Ω.

    Fingerprints may be removed with a sort cloth moistened only with a few drops of water.
