GENERAL SAFETY SUMMARY
■Read This before Using the Instrument
This instrument should only be used by persons with sufficient knowledge of electronics who
thoroughly understand the contents of this manual.
This instrument is not designed or manufactured for households or ordinary consumers.
If unqualified personnel are to use the instrument, be sure the instrument is handled under the
supervision of qualified personnel (those who have electrical knowledge). This is to prevent the
possibility of personal injury or damage to the instrument.
■Note about Reading This Manual
The contents of this manual contain specialized terminology and may be difficult to understand. If
you have any questions about the contents of this manual, please contact your local LEADER
agent.
■Symbols and Terms
The following symbols and terms are used in this instruction manual and on the instrument to
indicate important warnings and notes.
<Symbol>
This symbol appears in this instruction manual and on the instrument to
indicate an area where improper handling could result in personal injury,
damage to the instrument, or malfunction of the instrument or devices
connected to it.
When you encounter this symbol on the instrument, be sure to refer to the
information in this instruction manual that corresponds to the area that the
symbol marks.
<Term>
Ignoring the precautions that this term indicates could lead to death or
serious injury.
<Term>
Ignoring the precautions that this term indicates could lead to personal injury
or damage to the instrument.

II
GENERAL SAFETY SUMMARY
Read the warnings and information below thoroughly to avoid death, personal injury, and damage and
deterioration of the instrument.
■Warnings Concerning the Case and Panels
Do not remove the instrument's case or panels for any reason. Touching the internal components
of the instrument could lead to fire or electric shock.
Also, do not allow foreign materials, such as liquids, combustible matter, and metal, to enter the
instrument. Turning the instrument on when such materials are inside it could lead to fire, electric
shock, damage to the instrument, or some other accident.
■Installation Environment
• Operating Temperature Range
Use this instrument in a 0 to 40 °C environment. Using the instrument with its vents blocked or
in a high temperature environment could lead to fire.
Drastic changes in temperature, such as might be caused by moving the instrument between
two rooms with different temperatures, can damage the instrument by causing condensation to
form within it. If there is a possibility that the instrument has condensation within it, wait for
approximately 30 minutes before turning on the power.
• Operating Humidity Range
Use this instrument in an environment whose relative humidity is 85 %RH or less where there
is no threat of condensation forming.
Also, do not operate this instrument with wet hands. Doing so could lead to electric shock or
fire.
• Do Not Operate in an Explosive Atmosphere
Using this instrument in an environment where flammable gasses, explosive gasses, or steam
is emitted or stored could lead to an explosion or fire. Do not use the instrument in such an
environment.
• Do Not Insert Foreign Materials
Do not insert foreign materials, such as metal and flammable objects, through the vents or
allow liquid to enter the instrument. Such acts can lead to fire, electric shock, damage to the
instrument, or some other accident.
■If You Notice Something Wrong during Operation
If you notice smoke, fire, a strange smell, or something else that is wrong with the instrument
while you are operating it, stop operation immediately. Failing to do so could lead to fire. Turn
OFF the power switch, and remove the power cord from the outlet. After making sure that fire
has not spread anywhere, contact your local LEADER agent.

III
GENERAL SAFETY SUMMARY
■Warnings Concerning the Power Source
Do not use a power source with a voltage other than the rated power source voltage for the
instrument. Doing so could lead to fire.
Confirm the voltage of the power source before you connect the power cord to it.
Only use a power source whose frequency is 50/60 Hz.
Use a power cord that is appropriate for the voltage of the power source. Also, use a power cord
that meets the safety standards of the country that you are using it in.
Using a power cord that does not meet the standards could lead to fire. If the power cord is
damaged, stop using it, and contact your local LEADER agent. Using a damaged power cord
could lead to electrical shock or fire.
When removing the plug from the power outlet, do not pull on the cord. Pull from the plug.
■Warnings Concerning Grounding
The instrument has a ground terminal to protect the user and the instrument from electric shock.
Ensure that the product is properly grounded for safe operation.
■Cautions Concerning the Input and Output Connectors
To avoid damaging the instrument, only apply signals to the input connectors that conform to the
specifications in this instruction manual. Do not short or apply external voltage to the output
connectors.
Doing so could damage the instrument.
■Cautions Concerning the AC Adapter
Only use the specified type of AC adapter. Using a non-specified type of adapter could damage
the instrument and lead to fire.
We recommend you replace the AC adapter at least once every five years.
■If You Will Not Use the Instrument for an Extended Period of Time
If you will not use the instrument for an extended period of time, remove the power plug from the
outlet.

IV
GENERAL SAFETY SUMMARY
■Calibration and Repairs
This instrument has been carefully examined at the factory to ensure that its performance is in
accordance with the standards. However, because of factors such as parts wearing out over time,
the performance of the instrument may degrade. To ensure stable performance, we recommend
that you have the instrument calibrated regularly. Also, if the instrument malfunctions, repairs are
necessary. For repairs and calibration, contact your local LEADER agent.
■Routine Maintenance
When you clean the instrument, remove the power plug from the outlet.
Do not use thinner or benzene when you clean the instrument's case, panels, or knobs. Doing so
could lead to paint chipping and the corrosion of plastic components. To clean the case, panels,
and knobs, use a soft cloth with mild detergent, and wipe gently. While cleaning, make sure that
foreign materials, such as water and detergent, do not enter the product. If liquid or a metal object
enters into the instrument, fire or electric shock may result.
■About the European WEEE Directive
This instrument and its accessories are subject to the European WEEE Directive.
Follow the applicable regulations of your country or region when discarding this instrument or its
accessories. Follow the EU Battery Directive when discarding the batteries that you removed from
this instrument.
(WEEE stands for Waste Electrical and Electronic Equipment.)
Follow the warnings and precautions that have been listed in this section to use the instrument
correctly and safely. Precautions are also contained in various other sections of this instruction manual.
To use the instrument correctly, be sure to follow those precautions as well.
If you have any questions or comments about this instruction manual, please contact your local
LEADER agent.
