DANGER

WARNING

CAUTION

For Safety

iii

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

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.

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.

8. 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.

WARNING

9. 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.

10.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.

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.

Optical units for MW9076 Series Optical Time Domain Reflectometer

have Class 1, 1M laser emitting parts as specified in IEC 60825-1, or

Class I, II parts as specified in 21 CFR 1040.10 (Refer to Table 1).

The explanatory labels shown on “Laser Radiation Markings” are

attached

Never use optical instruments to directly view Class 1M laser products.

Doing so may result in serious damage to the eyes.

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.

Laser Safety

For Safety

vii

Class 1, 1M indicate the danger degree of the laser radiation specified

below according to IEC 60825-1.

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 mn ;

b) for collimated beams, if the user views the laser output

with certain optical instruments ( for example , telescopes

and binoculars ).

And, Class I, IIa, II indicate the degree of danger of the laser radiation

outlined below as defined by 21 CFR 1040.10.

Class I: Class I labels of laser radiation are not considered to be

hazardous.

Class IIa: Class IIa labels 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 labels of laser radiation are considered to be a

chronic viewing hazard. The wavelength range of laser

radiating is in 400 to 710 nm.
