For Safety

For safety, do not open the equipment covers.

If repair is required, contact the sales representative, branch office, or agent at the

telephone number and address given in this document or in the equipment opera-

tion manual.

Although not recommended by Anritsu Corporation, if it is really imperative to

open the covers for emergency repair, take great care not to touch any dangerous

parts. Always request repair by a trained engineer who understands the hazards.

Anritsu Corporation will not accept liability for any injuries sustained as a result of

opening the equipment covers.

Part Names & Part Numbers

Please specify the part numbers shown in the parts list when making

inquiries or when ordering parts. There may be a difference between

the names of parts used in this manual and the parts actually used in

the equipment or supplied for repair. This is because equivalent

parts with the same functions, performance and reliability as the

parts specified in the circuit diagrams and parts list have been used

or supplied. Since the parts are equivalent, they have absolutely no

adverse effect on the equipment specified functions, performance or

reliability.

For Safety

WARNING

1. ALWAYS refer to the operation manual when working near loca-

tions 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 performance may be reduced.

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

descriptions indicating other dangers.

2. Laser radiation warning

• NEVER look directly into the cable connector on the equip-

ment nor into the end of a cable connected to the equipment.

If laser radiation 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 connec-

tor.

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 equip-

ment, 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 ser-

vice this equipment. There are high-voltage parts in this equip-

ment presenting a risk of severe injury or fatal electric shock to

untrained personnel. In addition, there is a risk of damage to pre-

cision parts.

5. This equipment should be used in the correct position. If the cabi-

net is turned on its side, etc., it will be unstable and may be dam-

aged if it falls over as a result of receiving a slight mechanical

shock.

WARNING

Falling Over

For Safety

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.

T___A indicates a time-lag fuse.

___A or F___ A 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

obstructed. If the ventilation is obstructed, the cabinet may

overheat and catch fire.

Laser Radiation Markings

For Safety

vii

For Safety

WARNING

Class 1 Safe laser presenting no danger when used according to

design specifications.

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

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

the eyes is eliminated by the eye avoidance reaction in-

cluding 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 radiat-

ing at other wavelengths, the degree of danger to the na-

ked 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 observed.
