WARNING
1. ALWAYS refer to the operation manual when working near locations
at which the alert mark shown on the left is attached. If the advice in
the operation manual is not followed there is a risk of personal injury
or reduced equipment performance. The alert mark shown on the
left may also be used with other marks and descriptions to indicate
other dangers.
2. IEC 61010 Standard
The IEC 61010 standard specifies four categories to ensure that an
instrument is used only at locations where it is safe to make
measurements. This instrument is designed for measurement
category I (CAT I). DO NOT use this instrument at locations
specified as category II, III, or IV as defined below.
Measurement category I (CAT I):
Secondary circuits of a device that is not directly connected to a
power outlet.
Measurement category II (CAT II):
Primary circuits of a device that is directly connected to a power outlet,
e.g., portable tools or home appliance.
Measurement category III (CAT III):
Primary circuits of a device (fixed equipment) to which power is
supplied directly from the distribution panel, and circuits running from
the distribution panel to power outlet.
Measurement category IV (CAT IV):
Building service-line entrance circuits, and circuits running from the
service-line entrance to the meter or primary circuit breaker
(distribution panel).

WARNING
3. Laser radiation warning
•NEVER look directly into the cable connector on the equipment
nor into the end of a cable connected to the equipment. There is
a risk of injury if laser radiation enters the eye.
•The Laser Safety label is attached to the equipment for safety use
as indicated in "Laser Safety" later in this section.
4. To ensure that the instrument is earthed, always use the supplied 3-
pin power cord, and insert the plug into an outlet with an earth
terminal. If power is supplied without earthing the equipment, there
is a risk of receiving a severe or fatal electric shock or causing
damage to the internal components.
5. This equipment cannot be repaired by the operator. DO NOT attempt
to remove the equipment covers or unit covers or to disassemble
internal components. Only qualified service personnel 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.
6. The performance-guarantee seal verifies the integrity of the equipment.
To ensure the continued integrity of the equipment, only Anritsu service
personnel, or service personnel of an Anritsu sales representative,
should break this seal to repair or calibrate the equipment. If the
performance-guarantee seal is broken by you or a third party, the
performance of the equipment cannot be guaranteed. Be careful not
to break the seal by opening the equipment or unit covers.
7. This equipment should always be positioned in the correct manner.
If the cabinet is turned on its side, etc., it will be unstable and may be
damaged if it falls over as a result of receiving a slight mechanical
shock.
Always set up the equipment in a position where the power switch
can be reached without difficulty.

CAUTION
1. Always remove the mains power cable from the power outlet before
replacing blown fuses. There is a risk of electric shock if fuses are
replaced with the power cable connected. Always use new fuses of
the type and rating specified on the rear panel of the instrument.
There is a risk of fire if a fuse of a different rating is used.
T5A indicates a time-lag fuse.
2. Keep the power supply and cooling fan free of dust.
•Clean the power inlet regularly. If dust accumulates around the
power pins, there is a risk of fire.
•Keep the cooling fan clean so that the ventilation holes are not
obstructed. If the ventilation is obstructed, the cabinet may
overheat and catch fire.

Class 1, 1M indicate the danger degree of the laser radiation specified
below according to IEC 60825-1:2001.
Class 1: Lasers that are safe under reasonably foreseeable conditions
of operation, including the use of optical instruments for
intrabeam viewing.
Class 1M: Lasers emitting in the wavelength range from 302.5 to 4000
nm that are safe under reasonably foreseeable conditions of
operation, but may be hazardous if the user employs optics
within the beam. Two conditions apply:
a) for diverging beams, if the user views the laser output with
certain optical instruments (for example, eye loupes,
magnifiers and microscopes) within a distance of 100 mm;
or
b) for collimated beams, if the user views the laser output with
certain optical instruments (for example, telescopes and
binoculars).
Class I, IIa, II, IIIa, IIIb indicate the degree of danger of the laser radiation
outlined below as defined by 21 CFR 1040.10:1995.
Class I: Class I levels of laser radiation are not considered to be
hazardous.
Class IIa: Class IIa levels of laser radiation are not considered to be
hazardous if viewed for any period of time less than or equal
to 1×103seconds but are considered to be a chronic viewing
hazard for any period of time greater than 1×103seconds.
The wavelength range of laser radiating is in 400 to 710 nm.
Class II: Class II levels of laser radiation are considered to be a chronic
viewing hazard. The wavelength range of laser radiating is
in 400 to 710 nm.
Class IIIa: Class IIIa levels of laser radiation are considered to be,
depending upon the irradiance, either an acute intrabeam
viewing hazard or chronic viewing hazard, and an acute
viewing hazard if viewed directly with optical instruments.
The wavelength range of laser radiating is in 400 to 710 nm.
Class IIIb: Class IIIb levels of laser radiation are considered to be an
acute hazard to skin and eyes from direct radiation.

For Safety
vii
CAUTION
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
The use of optical instruments with this product will increase eye hazard.

WARNING
Before using this instrument, always ensure that the warning light is lit
when the optical output switch is turned on.
If this warning light does not turn on, the equipment may be faulty and for
safety reasons should be returned to an Anritsu service center or
representative for repair.
The laser in the plug-in unit provided for this equipment is classified as
Class 1, 1M according to the IEC 60825-1:2001 standard, or as Class I,
IIIb according to the 21 CFR 1040.10:1995 standard.
Never use optical instruments to directly view Class 1M laser products.
Doing so may result in serious damage to the eyes.
