IMPORTANT NOTES
In
addition to
the items
listed
under
Safety Precautions
on
page
2,
please read
and adhere
to
the
following:
[Power
Supply]
#
When
making any connections
with
other devices, always
turn
off
the
power
to
all
equipment
first;
this
will
help
prevent
damage
or malfunction.
•
Do
not
use
this unit
on
the
same
power
circuit
with
any
device
that
will
generate
line
noise,
such as a motor
or
variable
lighting
system.
[Placement]
[Memory
Backup]
t
The
unit
contains
a
battery
which
maintains the contents
of
memory
while the
main power
Is off.
The
expected
life
of
this
battery
is
5 years
or
more. However,
to
avoid the
unexpected
loss of
memory
data,
it
is
strongly
recom-
mended
that
you change
the
battery
every 5 years.
Please be aware
that
the actual
life
of the battery
will
depend
on
the physical environment
(especially
temperature)
in
which the
unit
is
used.
When
it
is
time
to
change
the
battery,
consult
with qualified service
personnel.
This
unit
may
interfere with radio
and
television reception.
Do
not
use
this unit
in
the
vicinity
of
such
receivers.
[Maintenance]
•
For
everyday
cleaning
wipe the
unit with
a
soft,
dry
cloth
(or
one
that
has been
slightly
dampened
with water).
To
remove
stubborn
dirt,
use a
mild neutral detergent.
Afterwards, be
sure
to
wipe
the
unit
thoroughly
with
a
soft,
dry
cloth.
'
The
unit's
battery functions
during
normal
operation
as
well
as maintaining the contents
of
memory when
the
main
power
supply
is
turned
off.
When
the battery
becomes
weak,
there
is
a
risk of losing the contents of
the
memory. To
avoid the unexpected
loss of
memory
data, replace the
battery
before
it
becomes
weak.
'
When
the battery
becomes
weak, the
following
message
will
appear
in
the
display: "Internal Battery
Low". Please
change
the
battery
as soon as
possible
to
avoid the
loss
of
memory
data.
•
Never use benzene,
thinners, alcohol or solvents of
any
kind, to
avoid the
risk of discoloration and/or deformation.
[Additional Precautions]
•
Protect the
unit
from
strong impact.
•
Never
strike
or apply strong pressure
to
the
display.
•
A
small
amount
of
heat
will
radiate
from
the
unit,
and
thus
should be considered normal.
•
Before using the
unit
in
a
foreign country, consult with
qualified service personnel.
Please be aware
that
the contents
of
memory may
at
times
be
lost;
when
the
unit
is
sent
for repairs or
when
by
some
chance
a
malfunction
has
occurred. Important data
should
be
stored
on a
DATA
card, or written
down
on
paper. During
repairs,
due
care
is
taken
to
avoid the
loss
of data.
However,
in
certain
cases, (such
as
when
circuitry related to
memory
itself is
out of order)
we
regret
that
it
may
be
impossible
to restore
the
data.
[Expansion Board]
•When
using the optional
expansion board,
refer to the
expansion board manual
for
the instructions
on
installation
and use
of
the board.
