Your DTX will give you years of reliable service if you follow the simple rules given below: 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. Power Supply Always use the supplied Yamaha AC Adaptor (PA-1207, PA-3B or an equivalent) to power your DTX. Other adaptors may cause damage to the DTX. 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 DTX. 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 DTX 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. 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 DTX or otherwise subjecting it to strong physical shocks can damage it. Handle it with care. Electrical Interference The DTX contains digital circuitry and may cause interference or noise if placed too close to TV sets, radios, or similar equipment. If such a problem does occur, move the DTX further away from the affected equipment. Memory Back-up The DTX contains a special long-life battery that retains the contents of its internal RAM memory even when the power is turned OFF. The backup battery should last for several years. When the back-up battery needs to be replaced, the message "ERR-Low battery" will momentarily appear on the display when you turn the power ON. When this happens, have the back-up battery replaced by qualified Yamaha service personnel. DO NOT ATTEMPT TO REPLACE THE BACKUP BATTERY YOURSELF. Transfer important data from your DTX to a MIDI data recorder such as the Yamaha MDF2 MIDI Data Filer for safe long-term storage. Yamaha cannot be held responsible for data loss caused by battery failure or improper operation of the DTX. Service and Modification The DTX contains no user-serviceable parts. Opening the case and/or tampering with the internal circuitry can lead to irreparable damage and will void the warranty. Refer all maintenance to qualified Yamaha service personnel. Third-party Software Yamaha cannot take any responsibility for software produced for this product by third-party manufacturers. Please direct any comments about such software to the manufacturer or their agents. Yamaha is NOT responsible for damage caused by improper handling or operation. Cleaning Clean the cabinet and panel with a soft dry cloth. A slightly damp cloth may be used to remove stubborn grime and dirt. Do not use solvents such alcohol, benzine, or thinner to clean the cabinet or panel. Avoid placing vinyl objects on top of the instrument. Vinyl can stick to and discolor the surface. 1
