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.

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.

Power Down
Description
The C-1200 has two methods to power down:
Normal and Forced Power Down.
The normal power down method will save the
system state and end any running processes. The
state is saved for the next time the instrument is
turned back on.
The forced power down method only does a
minimum state save.
Normal Power
Down
Press the power button. The system will
automatically handle the power down procedure
in the following order:
The system state is saved.
Outstanding processes are closed in sequence.
The system enters standby mode (the power
key changes from orange to blue).
Note
The process takes about 10 seconds.
Forced Power
Down
Press and hold the power button for 4 seconds
until the system turns off and the power button
turns blue.
Note
The forced power down mode might cause the C-
1200 to perform a longer system check the next
time it is powered up.
