• Since these speakers are to be wall / ceiling mounted, it is essential that they are firmly secured. Be sure to consult a reliable source about the best type of fastener for your particular wall / ceiling’s construction. • Do not attach them to thin plywood or soft wall / ceiling 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 wall / ceiling 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. • When changing the angle of the speakers, be sure to adjust the angle after loosening the knob on the both sides. The speakers may be damaged by excessive power. • Lower the power amplifier / receiver volume control before changing input sources. Always turn the amplifier / receiver 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 modify or fix the speakers. Contact qualified Yamaha service personnel when any service is needed. The cabinet should never be opened for any reasons. • 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. After unpacking, please inspect contents to confirm all the following items are contained.

English 1 UNPACKING 2 BEFORE INSTALLATION 3 MOUNTING THE SPEAKERS Notes: • When using the brackets to mount the speakers on a wall / ceiling, please use safety wire (not included) between the bracket and the wall / ceiling to prevent the speaker from falling. • When adjusting the angle with the bracket fixed to the speaker, loosen the knobs on both sides before changing the direction of the speaker. (Angle adjustment can be performed after the knobs, fastened tightly, are loosened by rotating them 2 to 2-1/2 times.) When excessive force is applied while the knob is tightly shut, the fixed portion may collapse and angle adjustment will be disabled. After adjusting the angle, tighten the knob so that the speaker will be steadfast. If speaker cable (not included) is being fed from a hole in the wall / ceiling behind the bracket, pull this speaker cable through the hole in the bracket before mounting the bracket [figure - ]. 4 CONNECTING YOUR AMPLIFIER / RECEIVER Notes: • Do not let the bare speaker wires touch each other as this could damage the speaker or amplifier / receiver, or both. • Make sure the terminal is gripping the bare wire,...
