Indicates actions that require caution.
To prevent danger to humans and damage to property, be sure to follow the following instructions:

-ii-
DANGER
Do not disassemble
or modify the unit.
Doing so could cause
accidents such as
injury, electrical
shock, and fire, or
malfunction. For
inspection and
adjustment of the
balance, contact our
Sales Office or
Technical Service
Division.
Only use the
specified power
source.
Use of other types of
power sources may
result in heat
generation, fire, or
malfunction of the
balance.
Only use the
dedicated AC
adapter.
Use of other types of
AC adapters may
result in heat
generation, fire, or
malfunction of the
balance.
Do not touch the
AC adapter with
wet hands.
Doing so could result
in an electrical shock,
which may cause an
accident with injury or
death.

Safety Precautions
-iii-
CAUTION
When the balance
is not waterproof
and dustproof, do
not expose the
balance to rain,
water, dust, or such
other environment.
Even though the
balance is
waterproofed and
dustproofed, water
and dust may enter
the unit if the
connector cap to the
underfloor weigher
hole is detached.
Accurate
measurement may be
rendered impossible
in a location where
the balance is
subjected to rain or
water, or in a dusty
environment.
Do not lay the AC
adapter cable on
the surface of a
passage.
Somebody may trip
on the cable, causing
the balance to fall,
thereby causing injury
and/or damage to the
balance.
Do not move the
balance when a
sample is loaded.
The loaded sample
may fall off the pan
and cause an injury
and/or damage to the
sample and
surrounding objects.
Do not place the
balance on an
unstable base or
use the balance in a
location where it
may be subjected
to vibration.
The loaded sample
may fall off the pan
and cause an injury
and/or damage to the
sample and
surrounding objects.
Accurate
measurement may be
rendered impossible.

-iv-
Avoid applying
excess force or
impact to the
balance.
To prevent breakage
or malfunction, place
the sample to be
measured on the
balance carefully.
Do not use volatile
solvents for
cleaning.
The body may be
distorted. To clean the
unit of stains, use a
piece of dry cloth or
cloth soaked in a
small quantity of
neutral detergent.

Safety Precautions
-v-
Do not use the balance in the following places:
Location where it
may be subject to
air from an
air-conditioning
unit:
Extreme changes in
the ambient
temperature may
result in inaccurate
measurements.
Location where it
may be subjected
to abrupt changes
in ambient
temperature or
humidity:
Accurate
measurement may be
rendered impossible.
Use the balance in an
ambient temperature
range of 5°C to 35°C
and with 80% or lower
relative humidity.
Location where it is
subject to direct
sunlight:
An internal
temperature increase
in the balance may
lead to inaccurate
measurement.
Unstable base or
location where it
may be subjected
to vibration:
In addition to failing to
measure the sample
accurately, the loaded
sample may fall off
the pan and cause an
injury.
Soft floor:
When loaded with a
sample, the balance
may tip or move,
preventing accurate
measurements from
being conducted.
Tilted surface:
When the balance is
tilted, an error may be
caused, preventing
accurate
measurement from
being conducted.
Place the balance on
a level surface.

-vi-
Respect the following:
Be sure to calibrate
the balance after
installation or
relocation.
Measurement values
may contain errors. To
maintain accurate
measurement, be
sure to calibrate the
balance.
Do not leave the
balance
overloaded. (When
it is overloaded,
o-Err is displayed.)
To prevent breakage
or malfunction,
remove the sample
placed on the balance
immediately.
If the balance is to
be unused for an
extended period of
time, unplug the AC
adapter.
To conserve power
and to prevent
deterioration, unplug
it.
CAUTION (battery handling)
Never disassemble or modify the
batteries. Take care to ensure
you insert batteries with the
positive and negative poles
correctly inserted, and be careful
about short circuits.
Such mishandling could damage the
batteries, or cause the balance to fail
or ignite.
Do not put the batteries into a fire.
They may explode.
Do not mix old and new batteries,
or batteries of different types or
manufacturers.
If the balance is not going to be used
for a long time, store it with the
batteries removed.
Do not use batteries that leak. Observe the precautions printed on
the batteries or rechargeable
batteries.

Safety Precautions
-vii-
Dispose of batteries in
accordance with local
regulations.
