Immediately turn the power off, remove the AC adaptor from the 
outlet, and request servicing by your retailer, the nearest Roland 
Service Center, or an authorized Roland distributor, as listed on the 
“Information” page when:
•  The AC adaptor, the power-supply cord, or the plug has been 

damaged; or

•  If smoke or unusual odor occurs
•  Objects have fallen into, or liquid has been spilled onto the unit; 

or

•  The unit has been exposed to rain (or otherwise has become 

wet); or

•  The unit does not appear to operate normally or exhibits a 

marked change in performance.

In households with small children, an adult should provide 
supervision until the child is capable of following all the rules 
essential for the safe operation of the unit.
Protect the unit from strong impact.
(Do not drop it!)
Do not force the unit’s power-supply cord to share an outlet with 
an unreasonable number of other devices. Be especially careful 
when using extension cords---the total power used by all devices 
you have connected to the extension cord’s outlet must never 
exceed the power rating (watts/amperes) for the extension cord. 
Excessive loads can cause the insulation on the cord to heat up 
and eventually melt through.
Before using the unit in a foreign country, consult with your 
retailer, the nearest Roland Service Center, or an authorized Roland 
distributor, as listed on the “Information” page.
Batteries must never be recharged, heated, taken apart, or thrown 
into fire or water. 
 
 

Never expose batteries to excessive heat such as sunshine, fire or 
the like.
Incorrect handling of batteries, rechargeable Ni-MH battery, or a 
battery charger can cause leakage, overheating, fire, or explosion. 
Before use, you must read and strictly observe all of the precau-
tions that accompany the batteries, rechargeable Ni-MH battery, or 
battery charger. 
When using rechargeable Ni-MH battery and a charger, use only 
the combination of rechargeable Ni-MH battery and charger 
specified by the battery manufacturer.

The unit and the AC adaptor should be located so their location or 
position does not interfere with their proper ventilation.
This (BA-55) for use only with Roland stand ST-A95. Use with other 
stands is capable of resulting in instability causing possible injury.
Even if you observe the cautions given in the owner’s manual, 
certain types of handling may allow this product to fall from the 
stand, or cause the stand to overturn. Please be mindful of any 
safety issues before using this product.
Always grasp only the plug on the AC adaptor cord when plugging 
into, or unplugging from, an outlet or this unit.
At regular intervals, you should unplug the AC adaptor and clean it 
by using a dry cloth to wipe all dust and other accumulations away 
from its prongs. Also, disconnect the power plug from the power 
outlet whenever the unit is to remain unused for an extended 
period of time. Any accumulation of dust between the power plug 
and the power outlet can result in poor insulation and lead to fire.
Try to prevent cords and cables from becoming entangled. Also, 
all cords and cables should be placed so they are out of the reach 
of children.

Never climb on top of, nor place heavy objects on the unit.

Never handle the AC adaptor or its plugs with wet hands when 
plugging into, or unplugging from, an outlet or this unit.
Before moving the unit, disconnect the AC adaptor and all cords 
coming from external devices.
Before cleaning the unit, turn off the power and unplug the AC 
adaptor from the outlet (p. 10).
Whenever you suspect the possibility of lightning in your area, 
disconnect the AC adaptor from the outlet.
If used improperly, batteries may explode or leak and cause 
damage or injury. In the interest of safety, please read and observe 
the following precautions (p. 9).
•  Carefully follow the installation instructions for batteries, and 

make sure you observe the correct polarity.

•  Avoid using new batteries together with used ones. In addition, 

avoid mixing different types of batteries.

•  Remove the batteries whenever the unit is to remain unused for 

an extended period of time.

•  If a battery has leaked, use a soft piece of cloth or paper 

towel to wipe all remnants of the discharge from the battery 

compartment. Then install new batteries. To avoid inflammation 

of the skin, make sure that none of the battery discharge gets 

onto your hands or skin. 

Exercise the utmost caution so that none of the discharge gets 

near your eyes. Immediately rinse the affected area with running 

water if any of the discharge has entered the eyes.

•  Never keep batteries together with metallic objects such as 

ballpoint pens, necklaces, hairpins, etc.

Used batteries must be disposed of in compliance with whatever 
regulations for their safe disposal that may be observed in the 
region in which you live.
Batteries may reach a high temperature; please be careful to avoid 
burning yourself.
