Keep it in a safe place for future reference. these to the wall along with the speaker. REMOVING THE SPEAKER GRILLE •• As this unit is heavy, whenever it is moved, two people are required to transport it safely. •• Placing the speaker too close to a CRT-type TV may impair the picture color or cause a buzzing noise. In this case, move the speaker away from the TV. This is not an issue with LCD and plasma TVs. •• Do not place the following objects on the speaker: Glass, china, etc. –– If glass etc. falls by vibrations and breaks, it may cause personal injury.

A vessel with water in it –– If the vessel falls by vibrations and water spills, it may cause damage to the speaker, and/or you may get an electric shock. •• When choosing a power amplifier for use with this device, make sure that the output power of the amplifier is lower than the power capacity of this device. Malfunction or fire may occur. 1. Remove the screws (4 pieces) from both sides. •• Do not place the speaker where it is liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. 2. Grasp the speaker grille with your fingers with 3. Pull the grille straight out from the speaker. your thumbs at the top edge of the main unit, then gently push with your thumbs to pry the grille loose. Do the same for the bottom edge. •• Even if the output power of the amplifier is lower than the power capacity of this device (program), use of excessive input signals resulting clipping may cause damage to the device. Malfunction or fire may occur especially when the following sounds or noises are generated: –– feedback, when using a microphone –– continuous and extreme volume sound from a musical instrument –– extreme continuous distorted sound –– noise caused by plugging/unplugging the cable while the amplifier is turned on •• Do not place the speaker where foreign objects such as water drips might fall.

Long-term use and vibrations may cause them to pull free. •• Do not attempt to clean the speaker with chemical solvents as this might damage the finish. Use a clean, dry cloth. •• Install the speaker in a cool, dry, clean place – away from windows, heat sources, sources of excessive vibration, dust, moisture and cold. Avoid sources of humming (transformers, motors). To prevent fire or electrical shock, do not expose the speaker to rain or water. be used. Select a screw which is suitable for use with the mounting bracket and can be fully inserted into the hole on the speaker. •• Do not fasten the speaker to the ceiling with nails, adhesives, or other Top panel •• When using an amplifier with a rated output power higher than the nominal input power of the speaker, care should be taken never to exceed the speaker’s maximum input. Caution •• The required length of a screw differs depending on the mounting bracket to •• Secure placement or installation is the owner’s responsibility. Yamaha shall not be liable for any accident caused by improper placement or installation of the speaker. •• Placing the speaker on the same shelf or rack as the turntable can result in feedback. •• Any time you note distortion, reduce the volume control on your amplifier to a lower setting. Never allow your amplifier to be driven into “clipping”. Otherwise the speaker may be damaged. CONNECTING TO YOUR AMPLIFIER To reattach, do these steps in reverse order. The 4 pegs inside the grille should be set in the corresponding holes on the speaker. Caution‌ BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE AMPLIFIER IS SWITCHED OFF.
