DANGER
●When replacing the battery, use the specified battery and insert it with
the correct polarity. If the wrong battery is used, or if the battery is
inserted with reversed polarity, there is a risk of explosion causing
severe injury or death.
●DO NOT expose batteries to heat or fire. This is dangerous and can
result in explosions or fire. Heating batteries may cause them to leak
or explode.
WARNING
●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.
●Overvoltage Category
This equipment complies with overvoltage category II defined in IEC
61010. DO NOT connect this equipment to the power supply of
overvoltage category III or IV.
●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.
●To ensure that the equipment is grounded, always use the supplied
3-pin power cord, and insert the plug into an outlet with a ground
terminal. If power is supplied without grounding the equipment, there
is a risk of receiving a severe or fatal electric shock or causing
damage to the internal components.

WARNING
●Only qualified service personnel with a knowledge of electrical fire and
shock hazards should service this equipment. This equipment cannot
be repaired by the operator. DO NOT attempt to remove the equipment
covers or unit covers or to disassemble internal components. 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.
●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. Be careful
not to break the seal by opening the equipment or unit covers. If the
performance-guarantee seal is broken by you or a third party, the
performance of the equipment cannot be guaranteed.
●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.
●DO NOT short the battery terminals and never attempt to disassemble
the battery or dispose of it in a fire. If the battery is damaged by any of
these actions, the battery fluid may leak.
This fluid is poisonous.
DO NOT touch the battery fluid, ingest it, or get in your eyes. If it is
accidentally ingested, 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 with clean water.

WARNING
●This equipment uses a Liquid Crystal Display (LCD). DO NOT subject
the equipment 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 with soap and water.

CAUTION
●Always remove the main power cable from the power outlet before
cleaning dust around the power supply and fan.
- 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.

The laser in this equipment is classified as Class 1 according to the IEC
60825-1:2007 standard, or as Class I according to the 21 CFR
1040.10:1995 standard. Class 1 and Class I are defined as below.
Class 1: Lasers that are safe under reasonably foreseeable conditions
of operation, including the use of optical instruments for
intrabeam viewing.
Class I: Class Ilevels of laser radiation are not considered to be
hazardous.
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.

CAUTION
This equipment uses a Poly-carbon monofluoride 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
4 years. It should be replaced before this period has elapsed.
The equipment is equipped with an internal hard disk from which, as with
any hard disk, data may be lost under certain conditions. It is
recommended to periodically back up all important data and programs to
protect them from being lost accidentally.
Anritsu will not be held responsible for lost data.
To reduce the possibility of data loss, particular attention should be given
to the following points.
●The equipment should only be used within the recommend
temperature range, and should not be used in locations where the
temperature may fluctuate suddenly.
●Always follow the guidelines to ensure that the equipment is set up in
the specified manner.
●Always ensure that the fans at the rear and side of the equipment are
not blocked or obstructed in any way.
●Exercise care not to bang or shake the equipment whilst the power is
on.
●Never disconnect the mains power at the plug or cut the power at the
breaker with the equipment turned on.
The life span of certain parts used in this equipment 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 equipment cannot be
guaranteed 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.
This equipment is designed for an industrial environment.
In a residential environment, this equipment may cause radio interference
in which case the user may be required to take adequate measures.
