Roland 074021E19, Service Notes

BK-5

5

• 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 “Informa-
tion” page.

.................................................................................................

• Do NOT play a CD-ROM disc on a conventional audio CD 

player. The resulting sound may be of a level that could 
cause permanent hearing loss. Damage to speakers or 
other system components may result..

• 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, discon-
nect 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 entan-

gled. 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 (see p. 20).

.................................................................................................

• Whenever you suspect the possibility of lightning in your 

area, disconnect the AC adaptor from the outlet.

When the BK-5 is turned off by the “Auto Off” function, the [POWER] button’s position doesn’t change, 

which means that you need to press it once, wait a few seconds, then press it again to switch the BK-5 back on.   

Energy saving function 

The BK-5 has an Auto Off function, which automatically switches off the power after a certain
amount of time has passed without any buttons being operated.
Shortly before the BK-5 shuts down automatically, the display starts counting down the seconds.
 If you want to keep using the BK-5 at this stage, press any button.
You can also disable the “Auto Off” function. For more about the Auto Off function, refer to p.69 on owner’s manual.
