Precautions Your RY20 will give you years of reliable service 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. • Direct sunlight, such as near a window. • High temperatures, for example, near a heat source, outdoors, or in a car during the daytime. • Excessive humidity. • Excessive dust. • Strong vibrations. s Power Supply Always use the supplied Yamaha AC Adaptor to power your RY20. Other adaptors may cause damage to the RY20. Also, make sure that the adaptor you have is appropriate for the AC mains supply voltage in the area where you intend to use the RY20. NOTE The correct INPUT voltage is marked on the top of the adaptor. Turn the power OFF and unplug the AC adaptor when the instrument is not in use. Unplug the AC adaptor during electrical storms. Avoid plugging the AC adaptor used with the RY20 into the same AC mains 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 and possibly damage. Turn off the power before making or breaking connections. To avoid damage to the instrument and other devices to which it is connected (a sound system, for example), always turn the power switches of all related devices OFF before connecting or disconnecting audio and MIDI cables. s Handling and Transport Never apply excessive force to the controls, connectors, or other parts of the instrument. Always plug and unplug any cables by gripping the connector, not the cord itself. Disconnect all cables before moving the instrument. Dropping the RY20 or otherwise subjecting it to strong physical shocks can damage it. Handle it with care. i
