Yamaha NS-AW390 Owners Manual - Page 2

CONSUMER PRECAUTIONS Read these precautions carefully before setting up your NS-AW190/NS-AW390 speakers. • When installing these speakers outdoors, try to minimize their exposure to rain and snow by mounting the speaker in corners or under eaves. • Since these speakers are to be wall mounted, it is essential that they are firmly secured. Be sure to consult a reliable source about the best type of hanger for your particular wall's construction. Secure installation is the purchaser's responsibility. • Do not attach them to thin plywood or soft wall surface materials as the screws may tear free, causing the speakers to fall and be damaged, or result in personal injury. • Do not fasten the speakers to walls with nails, adhesives, or other unsafe hardware. Long-term use and vibrations may cause them to pull free. • Do not place the speakers where they are liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. • Never touch the woofer or tweeter units with your hands or expose them to excessive physical shock. If they are dented or bent, the sound will be distorted. • Lower the power amplifier / receiver volume control before changing input sources. Never change input sources (for example, FM to CD) at high listening levels. Always turn the receiver / amplifier unit off when installing or removing input cables. • Anytime you note distortion, reduce the volume control on your power amplifier / receiver to a lower setting. Never allow your power amplifier to be driven into "clipping". • Do not attempt to clean the speakers with chemical solvents as this might damage the finish. To clean wipe with a dry, soft cloth. • Secure placement or installation is the owner's responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of speakers. 2
