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 opera-
tion, 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. When supplying power to this equipment, connect the accessory 3-
pin power cord to a grounded outlet. If a grounded 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.
3. 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 person-
nel. In addition, there is a risk of damage to precision parts.
4. 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.

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.
T3.15A indicates a time-lag fuse.
T3.15A indicate a normal fusing type fuse.
There is risk of receiving a fatal electric shock if the fuses are re-
placed 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 over-
heat and catch fire.
3. NEVER input a signal of more than the specified maximum power
between the measured terminal and ground. Input of an excessive
signal may damage the equipment.
