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 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 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 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 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 conver-

sion 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 knowl-

edge of electrical fire and shock hazards should service this equipment.

There are high-voltage parts in this equipment presenting a risk of se-

vere injury or fatal electric shock to untrained personnel. In addition,

there is a risk of damage to precision parts.
