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 operation,

etc., is performed without heeding the advice in the operation manual,

there is a risk of personal injury. In addition, the equipment perfor-

mance may be reduced.

Moreover, this alert mark is sometimes used with other marks and de-

scriptions indicating other dangers.

2. Laser radiation warning

•NEVER look directly into the cable connector on the equipment nor

into the end of a cable connected to the equipment. If laser radia-

tion enters the eye, there is a risk of injury.

•Laser Radiation Markings on a following page show the Laser

Safety label attached to the equipment near the cable connector.

3. When supplying power to this equipment, connect the accessory 3-pin

power cord to a 3-pin grounded power outlet. If a grounded 3-pin

outlet is not available, before supplying power to the equipment, use a

conversion adapter and ground the green wire, or connect the frame

ground on the rear panel of the equipment to ground. If power is

supplied without grounding the equipment, there is a risk of receiving

a severe or fatal electric shock.

4. This equipment cannot be repaired by the user. DO NOT attempt to

open the cabinet or to disassemble internal parts. Only Anritsu-

trained service personnel or staff from your sales representative with a

knowledge of electrical fire and shock hazards should service this

equipment. There are high-voltage parts in this equipment present-

ing a risk of severe injury or fatal electric shock to untrained personnel.

In addition, there is a risk of damage to precision parts.

Anritsu Corporation will not accept liability for any injuries sustained as

a result of opening the equipment covers.

5. This equipment should be used in the correct position. 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.

WARNING

6. 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.

7. DO NOT short the battery terminals and never attempt to disassemble

it 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 it, ingest it, or get in your eyes. If it is accidentally in-

gested, spit it out immediately, rinse your mouth with water and seek

medical help. If it enters your eyes accidentally, do not rub your eyes,

irrigate them with clean running water and seek medical help. If the

liquid gets on your skin or clothes, wash it off carefully and thoroughly.

8. 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 acci-

dentally, spit it out immediately, rinse your mouth with water and seek

medical help. If it enters your eyes accidentally, do not rub your eyes,

irrigate 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. Before changing the fuses, ALWAYS remove the power cord from the

poweroutlet and replace the blown fuses. ALWAYS use new fuses of

the type and rating specified on the fuse marking on the rear panel of

the cabinet.

Fuse label :

F10A indicate a normal fusing type 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 ob-

structed. If the ventilation is obstructed, the cabinet may overheat

and catch fire.

3. 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.

WARNING

Optical output safety is assured by the correct operation of the optical

output warning means. If the light emission from optical output warning

means cannot be confirmed at power-On or optical switch On before us-

ing the optical output, the warning means may be faulty. In this case,

don’t use the equipment and ask repair to Anritsu Corp. or the represen-

tative.

Class 1, Class 2 and Class 3 indicates the degree of danger of the laser

radiation outlined below as defined by JIS C60825-1, IEC60825-1 and

21CFR1040.10.

Class 1 Safe laser presenting no danger when used according to des-

ign specifications.

Class 2 Laser radiating in 400 to 700 nm wavelength range. In prin-

cipal, this class of laser is not safe, but the danger to the eyes

is eliminated by the eye avoidance reaction including the blink

response.

Class 3A Laser radiating in 400 to 700 nm wavelength range. The

danger to the eyes is eliminated by the eye avoidance reaction

including the blink response. For lasers radiating at other

wavelengths, the degree of danger to the naked eyes is not

greater than Class 1.

Class 3B The eyes will be damaged if direct laser radiation enters the

eyes. Normally there is no danger if the diffused beam is ob-

served.

This equipment is a Class-1 Laser Product as defined by the relevant

safety specifications (JIS C60825-1, IEC60825-1, 21CFR1040.10).

Class 1 is indicated at the rear panel of this equipment.
