serious injury or death and possible loss related to equipment malfunction. Follow all
precautions and procedures to minimize this risk.
Warning This indicates a risk from a hazardous condition or procedure that could result in
light-to-severe injury or loss related to equipment malfunction. Follow all precautions
and procedures to minimize this risk.
Caution
This indicates a risk from a hazardous procedure that could result in loss related to
equipment malfunction. Follow all precautions and procedures to minimize this risk.
This indicates a prohibited operation. The prohibited operation is indicated symbolically
in or near the barred circle.
This indicates a compulsory safety precaution. The required operation is indicated
symbolically in or near the circle.

For Safety
Warning Always refer to the operation manual when working near locations at which
the alert mark, shown on the left, is attached. If the operation, etc., is
performed without heeding the advice in the operation manual, there is a
risk of personal injury. In addition, the equipment performance may be
reduced.
Moreover, this alert mark is sometimes used with other marks and
descriptions indicating other dangers.
Warning
When supplying power to this equipment, connect the accessory 3-pin
power cord to a 3-pin grounded power outlet. If power is supplied without
grounding the equipment, there is a risk of receiving a severe or fatal
electric shock.
Warning This equipment can not be repaired by the operator. Do not attempt to
remove the equipment covers or to disassemble internal components.
Only qualified service technicians with a knowledge of electrical fire and
shock hazards should service this equipment. There are high-voltage parts
in this equipment presenting a risk of severe injury or fatal electric shock to
untrained personnel. In addition, there is a risk of damage to precision
components.
Warning
Use two or more people to lift and move this equipment, or use an
equipment cart. There is a risk of back injury if this equipment is lifted by
one person.
Caution
Electrostatic Discharge (ESD) can damage the highly sensitive circuits in
the instrument. ESD is most likely to occur as test devices are being
connected to, or disconnected from, the instrument’s front and rear panel
ports and connectors. You can protect the instrument and test devices by
wearing a static-discharge wristband. Alternatively, you can ground
yourself to discharge any static charge by touching the outer chassis of the
grounded instrument before touching the instrument’s front and rear panel
ports and connectors. Avoid touching the test port center conductors
unless you are properly grounded and have eliminated the possibility of
static discharge.
Repair of damage that is found to be caused by electrostatic discharge is
not covered under warranty.

MS4640A MM PN: 10410-00268 Rev. D Safety-3
Warning This product is supplied with a rechargeable battery that could potentially
leak hazardous compounds into the environment. These hazardous
compounds present a risk of injury or loss due to exposure. Anritsu
Company recommends removing the battery for long-term storage of the
instrument and storing the battery in a leak-proof plastic container. Follow
the environmental storage requirements specified in the product technical
data sheet.
