Make sure to have read the safety precautions described on pages 6 and 7 before using the
instrument for the first time.
Do not remove any covers from the instrument

In case of malfunctioning
Never continue to use the instrument if there are any symptoms of malfunctioning such as unusual
sounds, smell or smoke coming from the instrument. Immediately turn OFF the power and unplug
the power cord. When using an adapter for direct wiring to the power supply, immediately turn
OFF the power supply. Also disconnect the power to the equipment under measurement. Contact
your sales representative or nearest service center. Addresses may be found on the back cover of
this manual.
Power cord
Nothing should be placed on the power cord; it should also be kept away from any heat sources.
When unplugging the power cord from the outlet, never pull the cord itself. Always hold the plug
and pull it. If the power cord is damaged, contact your dealer for replacement. Refer to page 2 for
the part number when placing an order.
General Handling Precautions
Never place anything on top of the instrument
Never place another instrument or any objects containing water on top of the instrument.
Otherwise a failure may occur.
When moving the instrument
First disconnect the power of the equipment under measurement and disconnect the signal and
interface cables. Then turn the power of this instrument OFF and unplug the power cord.
Ventilation openings
Do not block the ventilation openings in order not to rise the internal temperature.
Electrically charged objects
Don’t bring electrically charged objects near the input terminals. The internal circuitry might be
damaged.
Cleaning
When cleaning the case or any other part of the instrument, first remove the power cord from the
consent (and in case of direct connection, disconnect the power lines). Do not use volatile
chemicals since this might result in dis-coloring etc. Always use a dry, soft cloth for cleaning.
When not using the instrument for a long time
When the instrument is not being used for an extensive period of time, unplug the power cord
from the outlet (when using an adapter for direct wiring to the power supply, disconnect the
power cord from the outlet).
