Roland TD-20 owner manual Additional Precautions

IMPORTANT NOTES

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 on a DATA card or in another MIDI device (e.g., a sequencer).

•Unfortunately, it may be impossible to restore the contents of data that was stored on a DATA card or in another MIDI device (e.g., a sequencer) 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.

•A small amount of heat will radiate from the unit during normal operation.

•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).

•Since sound vibrations can be transmitted through floors and walls to a greater degree than expected, take care not to allow such sound to become a nuisance to neighbors, especially at night and when using headphones. Although the drum pads and pedals are designed so there is a minimal amount of extraneous sound produced when they’re struck, rubber heads tend to produce louder sounds compared to mesh heads. You can effectively reduce much of the unwanted sound from the pads by switching to mesh heads.

•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.

•Use a cable from Roland to make the connection. If using some other make of connection cable, please note the following precautions.

•Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For infor- mation on cable specifications, contact the manufac- turer of the cable.

Before Using Cards

Using DATA Cards

•Carefully insert the DATA card all the way in—until it is firmly in place.

CompactFlash™

•Never touch the terminals of the DATA card. Also, avoid getting the terminals dirty.

•This unit’s memory card slot accepts CompactFlash memory cards. Microdrive storage media by IBM are not compatible.

•CompactFlash cards are constructed using precision components; handle the cards carefully, paying particular note to the following.

•To prevent damage to the cards from static electricity, be sure to discharge any static electricity from your own body before handling the cards.

•Do not touch or allow metal to come into contact with the contact portion of the cards.

•Do not bend, drop, or subject cards to strong shock or vibration.

•Do not keep cards in direct sunlight, in closed vehicles, or other such locations (storage temperature: -25 to 85° C).

•Do not allow cards to become wet.

•Do not disassemble or modify the cards.

*The explanations in this manual include illustrations that depict what should typically be shown by the display. Note, however, that your unit may incorporate a newer, enhanced version of the system (e.g., includes newer sounds), so what you actually see in the display may not always match what appears in the manual.
