 • Do not attempt to repair the unit, or replace parts within 
it (except when this manual provides specific instruc-
tions directing you to do so). Refer all servicing to your 
retailer, the nearest Roland Service Center, or an autho-
rized Roland distributor, as listed on the “Information” 
page.

heat-generating equipment); or are

........................................................................................................................
 006
 • When using the unit with the stand recommended by 
Roland (PDS-2), the stand must be carefully placed so it 
is level and sure to remain stable. If not using a stand, 
you still need to make sure that any location you choose 
for placing the unit provides a level surface that will 
properly support the unit, and keep it from wobbling.
........................................................................................................................
 008b
 • Use only the specified AC adaptor (BOSS PSA series), 
and make sure the line voltage at the installation 
matches the input voltage specified on the AC adaptor’s 
body. Other AC adaptors may use a different polarity, 
or be designed for a different voltage, so their use could 
result in damage, malfunction, or electric shock.
........................................................................................................................
 009
 • Do not excessively twist or bend the power cord, nor 
place heavy objects on it. Doing so can damage the cord, 
producing severed elements and short circuits. 
Damaged cords are fire and shock hazards!

 • This unit, either alone or in combination with an 
amplifier and headphones or speakers, may be capable 
of producing sound levels that could cause permanent 
hearing loss. Do not operate for a long period of time at 
a high volume level, or at a level that is uncomfortable. 
If you experience any hearing loss or ringing in the ears, 
you should immediately stop using the unit, and consult 
an audiologist.
........................................................................................................................

 • Do not allow any objects (e.g., flammable material, 
coins, pins); or liquids of any kind (water, soft drinks, 
etc.) to penetrate the unit.
........................................................................................................................
 012c
 • 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 or the power-supply cord has been 
damaged; or
