CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the instrument or other property. These precautions include, but are not limited to, the following:
Do not place the AC adaptor cord near heat sources such as heaters or radiators, and do not excessively bend or otherwise damage the cord, place heavy objects on it, or place it in a position where anyone could walk on, trip over, or roll anything over it. When removing the electric plug from the instrument or an outlet, always hold the plug itself and not the cord. Do not connect the instrument to an electrical outlet using a multiple-connector. Doing so can result in lower sound quality, or possibly cause overheating in the outlet. Unplug the AC power adaptor when not using the instrument, or during electrical storms. Before connecting the instrument to other electronic components, turn off the power for all components. Before turning the power on or off for all components, set all volume levels to minimum. Also, be sure to set the volumes of all components at their minimum levels and gradually raise the volume controls while playing the instrument to set the desired listening level. Do not expose the instrument to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel disfiguration or damage to the internal components. Do not use the instrument near other electrical products such as televisions, radios, or speakers, since this might cause interference which can affect proper operation of the other products. Do not place the instrument in an unstable position where it might accidentally fall over. Before moving the instrument, remove all connected adaptor and other cables. When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths. Also, do not place vinyl, plastic or rubber objects on the instrument, since this might discolor the panel or keyboard. Do not rest your weight on, or place heavy objects on the instrument, and do not use excessive force on the buttons, switches or connectors. Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed. Always turn the power off when the instrument is not in use. Use only the stand/rack specified for the instrument. When attaching the stand or rack, use the provided screws only. Failure to do so could cause damage to the internal components or result in the instrument falling over. Do not operate the instrument for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician.

When changing the batterhead, carefully remove the drum trigger sensors with a knife, etc. before loosening the head.
* Be careful not to pull the cord when removing the trigger.

Attach to the Bass Drum

Mount the drum trigger sensor on the batterhead of the bass drum close to the edge of the rim.
* Make sure the sensor does not come in contact with the rim.
Taking Care of the Drum Triggers
Make sure the surface of the batterhead or shell where the trigger is to be mounted is free from dirt and grime. Clean the surface with alcohol, etc. before attaching. To prevent broken trigger cords caused by the vibration of the drum rim, secure the sensors and cords in place with tape. Irregular vibration and sustained resonance on the batterhead or shell may cause double-triggering. This can be prevented by applying a mute to the batterhead and controlling excessive vibration. We recommend the use of the Yamaha Ring Mute. Once you have removed drum triggers and want to mount them again, be sure completely remove the old tape and apply new tape. Using used tape may cause problems such as poor sensitivity, double-triggering, etc.

Attach to the Snare Drum

Mount the drum trigger sensor on the batterhead of the snare drum close to the edge of the rim across player.

Attach to the Toms

Mount the drum trigger sensor on the shell close to the edge of the rim.
* Make sure the sensor does not come in contact with the rim. * Place the trigger in a position where other instruments (drum or percussion) will not influence it.
