This is normal, and is not a cause for concern. · The use of an AC adaptor is recommended as the unit's power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type. · When installing or replacing batteries, always turn off the power on this unit and disconnect any other devices you may have connected. This way, you can prevent malfunction and/or damage to speakers or other devices. · Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or damage to speakers or other devices. Placement · This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers. · Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to temperature extremes. Excessive heat can deform or discolor the unit. Maintenance · For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth. · Never use benzene, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/ or deformation. 3 Repairs and Data · Please be aware that all data contained in the unit's memory may be lost when the unit is sent for repairs. Important data should always be written down on paper (when possible). During repairs, due care is taken to avoid the loss of data. However, in certain cases (such as when circuitry related to memory itself is out of order), we regret that it may not be possible to restore the data, and Roland assumes no liability concerning such loss of data. · Unfortunately, it may be impossible to restore the contents of data that was stored in the unit's memory once it has been lost. Roland Corporation assumes no liability concerning such loss of data. · Use a reasonable amount of care when using the unit's buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions. · Never strike or apply strong pressure to the display. · When connecting / disconnecting all cables, grasp the connector itself--never pull on the cable. This way you will avoid causing shorts, or damage to the cable's internal elements. · To avoid disturbing your neighbors, try to keep the unit's volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about those around you (especially when it is late at night). · When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will need to use equivalent packaging materials. Memory Backup · Even while the unit's power is switched off, the battery serves in maintaining the contents of memory. When the battery becomes weak, there is a risk of losing the contents of memory. To avoid this, replace the battery as soon as you notice it has weakened. Additional Precautions · Please be aware that the contents of memory can be irretrievably lost as a result of a malfunction, or the improper operation of the unit. To protect yourself against the risk of loosing important data, we recommend that you periodically save a backup copy of important data you have stored in the unit's memory Setting Memo. 4 FEATURES · The DB-88 is a high-quality rhythm training machine equipped with quartz-precision timing. It readily accommodates a wide range of musical genres--from jazz or rock to classical. · It digitally indicates the tempo, which can be quickly and accurately changed with the dial. · You can adjust the volume of each rhythm ( , 3 , or ) independently and add accents freely. · It allows you to use voice as well as two types of click sounds for training. · You can set a complex beat (as well as a simple beat) by combining 1­8 beats. · It allows you to write eight different Metronome settings (Tempo, Beat, Tone and Level) and eight different reference notes into memory. · It features a Loop function, which can automatically play back a series of settings you have set up, allowing you to practice irregular rhythms or tempo changes in a song. · It detects and indicates the tempo through Tap Input, which allows you to see the tempo easily--simply by pressing the Tap button. · Since reference notes can be played chromatically, the unit can also be used for practicing wind instruments. · Features an input jack that allows for connecting a guitar or bass. It can be used as a headphones amplifier, so you can practice during the night time. Please note that although a battery was installed in your DB-88 when it was shipped from the factory, it has not been connected. You will need to refer to the section "Battery Replacement," for instructions on connecting the battery. 5 PANEL DESCRIPTIONS 1 6 7 8 9 10 15 16 2 17 34 6 5 11 12 13 14 1.
