RADIO AND TELEVISION INTERFERENCE
"Warning - This equipment has been verified to comply with the limits for a Class B computing device,
pursuant to Subpart J, of Part 15, of FCC rules. Operation with non>certified or non-verified equip
ment is likely to result in interference to radio and TV reception."
The equipment described in this manual generates and uses radio-frequency energy. If it is not
installed and used properly, that Is. in strict accordance with our instructions. It may cause interfer
ence with radio and television reception.
This equipment has been tested and found to comply with the limits for a Class B computing
device in accordance with the specifications in Subpart J. of Part 15, of FCC Rules. These rules are
designed to provide reasonable protection against such a interference in a residential installation.
However, there is no guarantee that the interference will not occur in a particular installation. If this
equipment does cause interference to radio or television reception, which can be determined by turning
the equipment on and off, the user is encouraged to try to correct the interference by the
following measure:
• Disconnect other devices and their input/output cables one at a time. If the interference stops, it
is caused by either the other device or its t 'O cable.
These devices usually require Roland designated shielded I/O cables. For Roland devices, you can
obtain the proper shielded cable from your dealer. For non Roland devices, contact the manufacturer
or dealer for assistance.
If your equipment does cause interference to radio or television reception, you can try to correct
the interference by using one or more of the following measures:
• Turn the TV or radio antenna until the interferences stops.
• Move the equipment to one side or the other of the TV or radio.
• Move the equipment farther away from the TV or radio.
• Plug the equiprnent into an outlet that is on a different circuit than the TV or radio. (That is, make
certain the equipment and the radio or television set are on circuits controlled by different circuit
breakers or fuses.)
• Consider installing a rooftop television antenna with coaxial cable lead-in between the antenna and
TV.
If necessary, you should consult your dealer or an experienced radio/television technician for
additional suggestions. You may find helpful the following booklet prepared by the Federal Com
munications Commision:

INSTRUCTIONS
FEATURES
The BOSS DSD-2 is an effect unit that features both the sampler func
tion 1800ms digital recorder) and the delay function (50 to 800ms).
The Trigger In Jack can be used to sync the OSD-2 with a rhythm
machine, or to sample a sound and use it as an external sound source,
or to obtain an echo effect that perfectly syncs to the rhythm.
> Please read these instructions carefully for proper operating procedures for the BOSS DSD-2.

NOTICE
»Please be sure to use the AC Adaptor BOSS PSA-120, 220 or 240 depending on the voltage
system in your country. ACA-series can not be used, as the DSD-2 draws more current (4560mA 9V DC) than usual compact effect units.
»The battery (one Dry Battery. 9V) will last for 30 minutes to 2 hours (manganese) or 5 to 10
hours (alkaline), depending on the conditions. The use of a BOSS PSA-Adaptor and alkaline
battery is recommended for a longer time performance.
»Avoid using this unit in extreme heat or humidity, or where it may be affected by dust.
CAUTIONS
»When the unit is not in use for a long
period, remove the battery to prevent pro
blems caused by the battery leakage.
»if the battery voltage drops, effect becomes
vague or no sound is produced. To prevent
that, replace the battery.
AC ADAPTOR (OPTION)
»Be sure to keep the battery securely con
nected even while using the AC Adaptor,
then the unit will continue to operate even
if the AC Adaptor cord comes out during
performance.
»To avoid wasting the battery unplug the
cord from the OUTPUT jack when the unit
is not in use.
> For AC operation, be sure to use the BOSS
AC Adaptor PSA-120, 220 or 240 depending
on the voltage system in your country, and
never use one Adaptor for two units simul
taneously.
CONNECTING
( Be sure to take off connecting plug from the Output when the unit is not used. ^
Power is switched on
when a plug is put
into Output Jack. (In
battery operation)
AMPLIFIER
•The microphone can be directly connected to the Input Jack
only when it has sufficient output.
