PRECAUTIONS PLEASE READ CAREFULLY BEFORE PROCEEDING * Please keep these precautions in a safe place for future reference. 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: • If the instrument is not to be in use for a long time, remove the batteries from it, in order to prevent possible fluid leakage from the battery. • Keep batteries away from children. • 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. • 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 or plastic 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. • 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. sREPLACING THE BACKUP BATTERY • This instrument contains a non rechargeable internal backup battery which permits internal data to remain stored even when the power is off. When the backup battery needs replacing, the message "Backup Batt. Low" will display in the LCD panel. When this happens, immediately back up your data (using an external device such as the floppy disk-based Yamaha MIDI Data Filer MDF2), then have qualified Yamaha service personnel replace the backup battery. • Do not attempt to replace the backup battery yourself, in order to prevent the possible serious hazards. Always have qualified Yamaha service personnel replace the backup battery. • Never place the backup battery in a location that a child can reach, since a child might accidentally swallow the battery. If this should happen, consult a physician immediately. sSAVING USER DATA • Save all data to an external device such as the Yamaha MIDI Data Filer MDF2, in order to help prevent the loss of important data due to a malfunction or user operating error. 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. Make sure to discard used batteries according to local regulations. 2 (4)
