Maintenance tips for your Onkyo speakers

• Clean the speakers regularly. Remove the speaker grill and vacuum it with a hose and dust attachment to remove dust and debris. Carefully use canned air and a camera lens brush to clean woofer, mid-range and tweeter components. Wipe down the cabinet using a cleaner recommended in the owner's manual for your speakers.
• Shut off the receiver or amplifier and remove the speaker wires from the back of the speaker cabinet. Clean the speaker wire terminals with cotton swabs dampened with isopropyl alcohol. Allow the terminals to completely dry before reconnecting speaker wires.
• Keep your speakers away from direct sunlight and extreme heat sources.
