SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow during
operation and storage. Read the following before
any operation to ensure your safety and to keep
the instrument in the best possible condition.
Safety Symbols
These safety symbols may appear in this manual or on the
instrument.
WARNING
Warning: Identifies conditions or practices that
could result in injury or loss of life.
CAUTION
Caution: Identifies conditions or practices that
could result in damage to the instrument or to
other properties.
DANGER High Voltage
Attention Refer to the Manual
Earth (ground) Terminal
Frame or Chassis Terminal
Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.

Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the instrument.
Avoid severe impact or rough handling that leads
to damaging the instrument.
Do not discharge static electricity to the instrument.
Use only mating connectors, not bare wires, for the
terminals.
Ensure signals to the RF input do not exceed
+30dBm.
Do not block the cooling fan opening.
Do not disassemble the instrument unless you are
qualified.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
instrument falls under overvoltage category II.
Overvoltage category IV is for equipment installed at or near
the origin of supply to a building, between the building
entrance and the main distribution board.
Overvoltage category III is for equipment intended to form
part of a building wiring installation.
Overvoltage category II is for equipment intended to be
supplied from the building wiring.
Overvoltage category I is not relevant to this standard.
Power Supply
WARNING
AC Input voltage range: 100V~240V (Max. 82W)
Frequency: 50 - 60Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to an
earth ground.

SAFETY INSTRUCTIONS

Power Cord
Requirements
The connector that plugs into the socket outlet must
be a grounding-type male plug designed for use in
your region. It must have certification marks showing
certification by an agency in your region. The
connectors that plug into the Appliance Inlets (AC
receptacle) must be an IEC 60320, sheet C13, female
connector. If the power cord supplied with the system
does not meet requirements for use in your region
discard the cord, do not use with adapters.
Cleaning
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 5°C to 45°C
Humidity: <90% (non condensing)
(Pollution Degree) EN 61010-1:2010 specifies the pollution
degrees and their requirements as follows. The instrument falls
under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of
dielectric strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity
caused by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due
to condensation which is expected. In such conditions,
equipment is normally protected against exposure to direct
sunlight, precipitation, and full wind pressure, but neither
temperature nor humidity is controlled.

environment
Location: Indoor
Temperature: -20°C to 70°C
Humidity: <90% (non condensing)
Altitude:< 2,000 meters
Disposal
Do not dispose this instrument as unsorted municipal
waste. Please use a separate collection facility or
contact the supplier from which this instrument was
purchased. Please make sure discarded electrical
waste is properly recycled to reduce environmental
impact.
Lifting and
carrying
WARNING
Use safe practices as follows when lifting.
Do not place any object on top of rack- mounted
devices.
