Roland R-88 User Manual

•  Do not connect this unit to same electrical 

outlet that is being used by an electrical 

appliance that is controlled by an 

inverter or a motor (such as a refrigerator, 

washing machine, microwave oven, or air 

conditioner). Depending on the way in which 

the electrical appliance is used, power supply 

noise may cause this unit to malfunction 

or may produce audible noise. If it is not 

practical to use a separate electrical outlet, 

connect a power supply noise filter between 

this unit and the electrical outlet.

•  The AC adaptor will begin to generate heat 

after long hours of consecutive use. 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 or rechargeable Ni-

MH type.

•  To prevent malfunction and equipment 

failure, always make sure to turn off the 

power on all your equipment before you 

make any connections.

•  When installing or replacing batteries, always 

turn this unit off and disconnect any other 

devices you may have connected. This way, 

you can prevent malfunction and damage.

•  If operating this unit on batteries, please 

use alkaline batteries or rechargeable Ni-MH 

batteries.

•  Using the unit near power amplifiers (or 

other equipment containing large power 

transformers) may induce hum. To alleviate 

the problem, change the orientation of this 

unit; or move it farther away from the source 

of interference.

•  This device may interfere with radio and 

television reception. Do not use this device 

in the vicinity of such receivers.

•  Noise may be produced if wireless 

communications devices, such as cell 

phones, are operated in the vicinity of this 

unit. Such noise could occur when receiving 

or initiating a call, or while conversing. 

Should you experience such problems, you 

should relocate such wireless devices so they 

are at a greater distance from this unit, or 

switch them off.

•  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.

•  Depending on the material and temperature 

of the surface on which you place the unit, its 

rubber feet may discolor or mar the surface. 

You can place a piece of felt or cloth 

under the rubber feet to prevent this from 

happening. If you do so, please make 

sure that the unit will not slip or move 

accidentally.

•  Do not place containers or anything else 

containing liquid on top of this unit. Also, 

whenever any liquid has been spilled on the 

surface of this unit, be sure to promptly wipe 

it away using a soft, dry cloth.

•  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 benzine, thinners, alcohol or 

solvents of any kind, to avoid the possibility 

of discoloration and/or deformation.

•  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 backed up USB flash drives, SD 

cards, SDHC cards, or 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.

•  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. Data stored on an SD card or 

USB flash drive has a finite lifespan, and may 

be lost simply with the passage of time. To 

protect yourself against the risk of loosing 

important data, we recommend that you 

back up important data to another location 

such as a computer.

•  Unfortunately, it may be impossible to 

restore the contents of data that was stored 

in the unit’s memory, USB flash drives, SD 

cards, SDHC cards, 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 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 others nearby, try to 

keep the unit’s volume at reasonable levels.

•  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.

•  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.

•  USB flash drives, SD cards, SDHC cards, are 

constructed using precision components; 

handle the memories, 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.

•  Do not allow cards to become wet.
•  Do not disassemble or modify the cards.

•  It is forbidden by law to make an audio 

recording, video recording, copy or 

revision of a third party’s copyrighted work
