WARNING
CAUTION

For Safety

DANGER
NEVER touch parts where the label shown on the left is attached. Such
parts have high voltages of at least 1 kV and there is a risk of receiving a
fatal electric shock.
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).

For Safety
iv
WARNING
3. 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.
4. 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.
5. 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.
6. 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.
7. This instrument uses a Liquid Crystal Display (LCD). DO NOT subject
the instrument to excessive force or drop it. If the LCD is subjected to
strong mechanical shock, it may break and liquid may leak.
This liquid is very caustic and poisonous.
DO NOT touch it, ingest it, or get in your eyes. If it is ingested
accidentally, spit it out immediately, rinse your mouth with water and
seek medical help. If it enters your eyes accidentally, do not rub
your eyes, rinse them with clean running water and seek medical help.
If the liquid gets on your skin or clothes, wash it off carefully and
thoroughly.

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.
T6.3A indicates a time-lag fuse.
There is risk of receiving a fatal electric shock if the fuses are
replaced with the power cord connected.
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.
3. Use two or more people to lift and move this equipment, or use a
trolley. There is a risk of back injury, if this equipment is lifted by one
person.
4. Never input a signal of more than the indicated value between the
measured terminal and ground. Input of an excessive signal may
damage the equipment.

CAUTION
This equipment uses a Poly-carbomonofluoride lithium battery to backup
the memory. This battery must be replaced by service personnel when
it has reached the end of its useful life; contact the Anritsu sales section
or your nearest representative.
Note: The battery used in this equipment has a maximum useful life of
7 years. It should be replaced before this period has elapsed.
This equipment uses memory cards as external storage media for
storing data and programs.
If this media is mishandled or becomes faulty, important data may be lost.
To prevent this chance occurrence, all important data and programs
should be backed-up.
Anritsu will not be held responsible for lost data.
Pay careful attention to the following points.
•Never remove the memory card from the pulse tester while it is being
accessed.
•The memory card may be damaged by static electric charges.
•Anritsu has thoroughly tested all external storage media shipped with
this instrument. Users should note that external storage media not
shipped with this instrument may not have been tested by Anritsu, thus
Anritsu cannot guarantee the performance or suitability of such media.
The life span of certain parts used in this instrument is determined by the
operating time or the power-on time. Due consideration should be given
to the life spans of these parts when performing continuous operation over
an extended period. The safety of the instrument cannot be gauranteed
if component parts are used beyond their life spans. These parts must
be replaced at the customer's expense even if within the guaranteed
period described in Warranty at the beginning of this manual.
For details on life-span, refer to the corresponding section in this manual.
Step attenuator: Refer to “5.3 Consumables.”
Cooling Fan: Refer to “5.3 Consumables.”
Back light of LCD: Refer to “5.3 Consumables.”
This instrument is designed for an industrial environment.
In a residential environment this instrument may cause radio interference
in which case the user may be required to take adequate measures.
