 V-Accordion

 

• 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 instrument during normal 

operation. This is perfectly normal.

• To avoid disturbing your neighbors, try to keep the instrument’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 instrument, package it in the box 

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

• Use Roland cables to make audio connections. If using some other make 

of connection cable, please note the following precautions.
Some connection cables contain resistors. Do not use cables that incorpo-
rate 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.

 

• The temperature range for use of the batteries depends on the battery 

type being used. Please see the documentation that came with the bat-
teries.

• Do not use or store batteries at high temperature, such as in strong direct 

sunlight, in cars during hot weather or directly in front of heaters. This 
may cause battery fluid leakage, impaired performance and shorten the 
batteries’ service life.

• Do not splash fresh or saltwater on a battery or allow the terminals to 

become damp. This may cause heat generation and formation of rust on 
the battery and its terminals.

• If newly purchased batteries exhibit rust, generate heat or seem abnormal 

in any other way, do not use them. Take them back to your dealer.

• Keep the batteries out of reach of babies or small children.

• Be sure to carefully instruct any person on the proper way of handling a 

battery.

• Never dispose of the battery in a fire. Never heat it. Doing so may melt 

the insulation, damage the gas release vents or protective devices, cause 
combustion through chemical reaction with generated hydrogen, ejec-
tion of battery fluid, bursting or fire.

• Do not use batteries with the positive (+) and negative (–) terminals 

reversed, as this may drain the batteries or cause abnormal chemical 
reactions.

• Do no strike or drop the batteries. Strong impact can cause leakage of 

battery fluid, heat generation, bursting or fire.

• Never try to connect several batteries in parallel as this may cause leak-

age of battery fluid, heat generation, bursting or fire.

• Do not alter or remove protective mechanisms or other parts. Never dis-

assemble the batteries.

• If any fluid from a battery comes in contact with the eyes, flush the eyes 

immediately, washing them thoroughly with clean water from a tap or 
other source and consult a doctor. Strong alkaline fluid can damage the 
eyes and lead to permanent loss of eyesight.

• If skin or clothing comes in contact with any fluid from the battery, wash 

the area immediately with clean water from a tap. Battery fluid can cause 
skin damage.

• When a battery is no longer usable, dispose of it in accordance with all 

applicable local laws and regulations.

• If a battery leaks fluid, changes color or shape or changes in any other 

way, do not use it, otherwise it may cause heat generation, bursting or 
fire.

 

• Incorrect handling of batteries, rechargeable batteries, or a battery 

charger can cause leakage, overheating, fire, or explosion. Before use, you 
must read and strictly observe all of the precautions that accompany the 
batteries, rechargeable batteries, or battery charger. When using 
rechargeable batteries and a charger, use only the combination of 
rechargeable batteries and charger specified by the battery manufacturer.

 

• Never unscrew the strap holder rings to avoid damaging the FR-2/FR-2b’s 

plastic housing, which eventually compromises overall stability and 
safety.
