Roland g-70 业主指南

G-70 Music Workstation 

r

• Do not use this instrument on the same power circuit with any 

device that will generate line noise (such as an electric motor or 
variable lighting system).

• Before connecting the G-70 to other devices, turn off the power 

to all units. This will help prevent malfunctions and/or damage to 
speakers or other devices.

• Although the LCD and LEDs are switched off when the POWER 

switch is switched off, this does not mean that the unit has been 
completely disconnected from the source of power. If you need to 
turn off the power completely, first turn off the POWER switch, 
then unplug the power cord from the power outlet. For this rea-
son, the outlet into which you choose to connect the power cord’s 
plug should be one that is within easy reach.

• Using the G-70 near power amplifiers (or other equipment con-

taining large power transformers) may induce hum. To alleviate 
the problem, change the orientation of this instrument or move it 
further away from the source of interference. 

• This instrument may interfere with radio and television reception. 

Do not use it in the vicinity of such receivers.

• Observe the following when using the unit’s floppy disk drive. For 

• Do not place the unit near devices that produce a strong mag-

netic field (e.g., loudspeakers).

• Install the G-70 on a solid, level surface.

• Do not move the unit or subject it to vibration while the drive is 

operating.

• Do not expose the G-70 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 G-70.

• To avoid possible breakdown, do not use the G-70 in a wet area, 

such as an area exposed to rain or other moisture.

• Do not allow objects to remain on the keyboard. This can be the 

cause of malfunction, such as keys ceasing to produce sound.

• For everyday cleaning wipe the G-70 with a soft, dry cloth or one 

that has been slightly dampened with water. To remove stubborn 
dirt, use a mild, non-abrasive detergent. Afterwards, be sure to 
wipe the instrument thoroughly with a soft, dry cloth.

• Never use benzene, thinner, alcohol or solvents of any kind, to 

avoid the possibility of discoloration and/or deformation.

• Please be aware that all data contained in the instrument’s mem-

ory may be lost when it is sent for repairs. 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. Roland assumes no 
liability concerning such loss of data.

• Please be aware that the memory contents can be irretrievably lost 

as a result of a malfunction or the improper operation of the 
instrument.

• Use a reasonable amount of care when using the G-70’s buttons, 

other controls and jacks/connectors. Rough handling can lead to 
malfunctions. 

• Never strike or apply strong pressure to the display.

• When connecting/disconnecting 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 G-70 during normal 

operation. This is perfectly normal.

• To avoid disturbing your neighbors, try to keep the G-70’s volume 

at reasonable levels. You may prefer to use headphones, so you do 
not need to be concerned about those around you (especially late 
at night). 

• When you need to transport the G-70, package it in the box 

(including padding) that it came in. Otherwise, you will need to use 
equivalent packaging materials or a flightcase.

• Use only the specified expression pedal (EV-5, EV-7; sold sepa-

rately). By connecting any other expression pedals, you risk caus-
ing malfunction and/or damage to the G-70.

• Wipe off stains on the touch screen using ethanol, but do not 

allow the ethanol to soak into the joint of the upper fume and the 
bottom glass, for it may otherwise cause peeling or malfunction. 
Do not use organic solvents or detergents other than ethyl alcohol 
(ethanol).

• Install the G-70 on a solid, level surface in an area free from vibra-

tion. If the unit must be installed at an angle, be sure the installa-
tion does not exceed the permissible range: upward, 2°; down-
ward, 18°.

• Avoid using the G-70 immediately after it has been moved to a 

location with a level of humidity that is greatly different than its 
former location. Rapid changes in the environment can cause con-
densation to form inside the drive, which will adversely affect the 
operation of the drive and/or damage floppy disks. When the unit 
has been moved, allow it to become accustomed to the new envi-
ronment (allow a few hours) before operating it.

• To insert a disk, push it gently but firmly into the drive—it will click 

into place. To remove a disk, press the EJECT button firmly. Do not 
use excessive force to remove a disk which is lodged in the drive.

• Never attempt to remove a floppy disk from the drive while the 

drive is operating (the indicator is lit); damage could result to both 
the disk and the drive.

• Remove any disk from the drive before powering up or down.

• To prevent damage to the disk drive’s heads, always try to hold the 

floppy disk in a level position (not tilted in any direction) while 
inserting it into the drive. Push it in firmly, but gently. Never use 
excessive force.

• To avoid the risk of malfunction and/or damage, insert only floppy 

disks into the disk drive. Never insert any other type of disk. Avoid 
getting paper clips, coins or any other foreign objects inside the 
drive.

• Floppy disks contain a plastic disk with a thin magnetic coating. 

Microscopic precision is required to enable storage of large 
amounts of data on such a small surface area. To preserve their 
integrity, please observe the following when handling floppy disks: 

• Never touch the magnetic medium inside the disk.

• Do not use or store floppy disks in dirty or dusty areas.
