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

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

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

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 1/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

you
can
try
to
correct
the
interference
by
using
one
or
more
of
the
following
measures:
Turn the TV or radio antenna until the interference 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
equipment
into
an
outlet
that
is
on
a
different

cause
trouble).
Md «Cautions»
e Please turn the DR-110 off, before con-
necting the AC Adaptor.
Connecting the AC Adaptor with the DR-
110 on may cause improper operation or
even break down.

«To avoid accidental loss of your
indispensable data»
e The DR-110 features a Memory back up
system that retains the data you have
written even when switched off, and this
is fully supported by battery power. So, to
avoid losing the data in memory, make
sure to keep the batteries securely con-
nected in the battery housing even while
using the AC Adaptor.
Please replace the whole set of the bat-
teries with a new set once a year, what-
ever the battery consumption may be like.
«Battery replacement is required in the
following cases»
@ In about 120 hours, if ordinary dry cell
type batteries are being used. (It varies
depending on the type of the cells and
how much the DR-110 has been used.)
e If the DR-110’s LCD (Liquid Crystal Dis-
play) becomes dimmer or flares, or the
sound or action of the unit becomes un-
stable.
«Battery Replacement»
e Please use 4 AA dry cells (UM-3).
Please be sure to turn the DR-110 off
and unplug the AC Adaptor if using one,
before battery replacement.
lf you have made battery replacement
within a few hours, data written in mem-
ory will be all protected finely.
Please avoid leaving exhausted batteries
connected,
or
trouble
may
be
caused
by battery leakage.
When using battery power, please do not
forget to turn off the Power Switch.
