Yamaha DD-50 Owner's Manual - Page 3

Congratulations Thank you for purchasing the Yamaha DD-50. The DD-50 has been developed to act and play like a drum set but with greater ease. Before you use the instrument, we recommend you to read through this manual. Taking Care of Your DD-50 Your DD-50 will give you years of playing pleasure if you follow the simple rules given below: s Location Do not expose the instrument to the following conditions to avoid deformation, discoloration, or more serious damage. q Direct sunlight (e.g. near a window). q High temperatures (e.g. near a heat source, outside, or in a car during the daytime). q Excessive humidity. q Excessive dust. q Strong vibration. s Power Supply q Turn the power switch OFF when the instrument is not in use. q An AC adaptor, if used (the DD-50 runs from either batteries or an optional AC adaptor), should be unplugged from the AC outlet if the instrument is not to be used for an extended period of time. q Unplug the AC adaptor during electric storms. q Avoid plugging the AC adaptor into the same AC outlet as appliances with high power consumption, such as electric heaters or ovens. Also avoid using multi-plug adaptors since these can result in reduced sound quality, operation errors, and possibly damage. s Turn Power OFF When Making Connections q To avoid damage to the instrument and other devices to which it is connected, turn the power switches of all related devices OFF prior to connecting or disconnecting cables. s Handling and Transport q Never apply excessive force to the controls, connectors or other parts of the instrument. q Always unplug cables by gripping the plug firmly, not by pulling on the cable. q Disconnect all cables before moving the instrument. q Physical shocks caused by dropping, bumping, or placing heavy objects on the instrument can result in scratches and more serious damage. s Cleaning q Clean the cabinet and panel with a dry soft cloth. q A slightly damp cloth may be used to remove stubborn grime and dirt. q Never use cleaners such as alcohol or thinner. q Avoid placing vinyl objects on top of the instrument (vinyl can stick to and discolor the surface). s Electrical Interference q This instrument contains digital circuitry and may cause interference if placed too close to radio or television receivers. If this occurs, move the instrument further away from the affected equipment. s Data Backup q Custom data and some settings (see page 21) will be retained in memory even if the power switch is turned OFF as long as an AC power adaptor is connected or batteries are installed. s Service and Modification q The DD-50 contains no user serviceable parts. Opening it or tampering with it in anyway can lead to irreparable damage and possibly electric shock. Refer all servicing to qualified YAMAHA personnel. YAMAHA is not responsible for damage caused by improper handling or operation. 1
