Boss Audio Systems GT-100 사용자 설명서

Immediately turn the unit 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; or

•  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.

When using the unit in locations 

where children are present, be 

careful so no mishandling of the 

unit can take place. An adult should 

always be on hand to provide 

supervision and guidance.

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.

The unit and the AC adaptor should 

be located so their location or 

position does not interfere with their 

proper ventilation.

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 it off 

and unplug the AC adaptor from the 

Whenever you suspect the possibility 

of lightning in your area, disconnect 

the AC adaptor from the outlet.

Be careful so you don’t get your 

fingers pinched when you handle 

any moving parts such as the 

following. Adult supervision is 

recommended whenever small 

children use the unit.

If you remove the screw from the 

ground terminal, be sure to replace 

it; don’t leave it lying around where 

it could accidently be swallowed by 

small children. When refastening the 

screw, make that it is firmly fastened, 

so it won’t come loose.
