Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

Repairs and Data

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.
When moved from one location to another where the temperature and/or humidity is very different, water droplets (condensation) may form inside the unit. Damage or malfunction may result if you attempt to use the unit in this condition. Therefore, before using the unit, you must allow it to stand for several hours, until the condensation has completely evaporated.
Please be aware that all data contained in the units 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.

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 write down important data you have stored in the units memory on paper.

Unfortunately, it may be impossible to restore the contents of data that was stored in the units 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 units buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.
When connecting / disconnecting all cables, grasp the connector itselfnever pull on the cable. This way you will avoid causing shorts, or damage to the cables internal elements.
To avoid disturbing your neighbors, try to keep the units 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.
When exchanging audio signals through a digital connection with an external instrument, this unit can perform recording without being subjected to some of the restrictions of the Serial Copy Management System (SCMS). This is because the unit is intended solely for musical production, and is designed not to be subject to restrictions as long as it is used to record works (such as your own compositions) that do not infringe on the copyrights of others. (SCMS is a feature that prohibits second-generation and later copying through a digital connection. It is built into MD recorders and other consumer digital-audio equipment as a copyright-protection feature.)
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 information on cable specifications, contact the manufacturer of the cable.
Do not use this unit for purposes that could infringe on a copyright held by a third party. We assume no responsibility whatsoever with regard to any infringements of third-party copyrights arising through your use of this unit.

You hear distortion or noise other than the playback sound from your computer The sound is too weak
Noise is heard in the sound
Has a mic or guitar been left connected? If a mic or guitar is connected to the UA-4FX, disconnect the mic or guitar and turn the input volume all the way toward the left (lowering the input level). Have you connected the grounding terminal? Connecting the chassis of your computer or the grounding terminal of your computers AC power cord to an electrical ground may solve the problem. Also, make sure that a device that produces a strong magnetic field, such as a television or microwave oven, is not located nearby. Could numerous audio devices be connected? Noise may occur if numerous audio devices are connected. Do not connect audio devices you are not using.
Sound of a device connected to the input jacks is distorted Insufficient volume from a device connected to the audio input/output jacks
Could the input/output level indicator be lit red? If youre inputting sound via the guitar/mic input jack or the mic input jack (plug-in powered mic or XLR type), use the UA-4FX's GUITAR/MIC input volume control to decrease the input level. If youre inputting sound via the line input jacks, use the INPUT volume control to decrease the input level. If youre inputting sound via the guitar/mic input jack, you should also check the setting of the input select switch. Noise may be entering via the line inputs or mic inputs. If a MIDI sound module with a USB connector is connected via USB to the same computer as the UA-4FX, and the output of the MIDI sound module is connected to the input jacks of the UA-4FX, noise from the computer may be heard via the MIDI sound module from the UA-4FX. In this case, you can either connect the MIDI sound module and UA-4FX in parallel via a self-powered hub, or connect the MIDI sound module in series or via a MIDI. Could two or more audio devices (such as the UA-4FX and a mixer) be connected to your computer? Try connecting only one UA-4FX to your computer. Check whether the noise disappears when only one UA-4FX is connected. In some cases, noise may occur if you connect numerous audio devices to your computer. If so, connect only the UA-4FX to your computer.
