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. 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.
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 personnel.
In addition, there is a risk of damage to precision parts.
Sure to read “For Safety” in the MP1632C Digital Data Analyzer Op-
eration Manual before repair. Then understand the contents of this
manual for repaire.

WARNING
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.
5. 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.
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 ob-
structed. If the ventilation is obstructed, the cabinet may overheat
and catch fire.
3. Use two or more people to lift and move this equipment, or use a trol-
ley. There is a risk of back injury, if this equipment is lifted by one
person.

CAUTION
This equipment uses a lithium battery to back-up the memory. This bat-
tery must be replaced by a service engineer when it has reached the end
of its useful life; contact the Anritsu sales section or your nearest repre-
sentative.
Remark: The battery limits approximately 7 years after purchasing data.
Advance change is preferable.
This equipment uses HDD and FDD as external media for storing data
and programs.
If this media is mishandled, important data may be lost. To prevent this
chance occurrence, all important data and programs should be back-up.
Anritsu will not be held responsible for lost data.
Pay careful attention to the following points.
•Never turn off the power, while the HDD is being accessed.
•Never give the equipment vibration or shock to avoid crush in the
HDD.
•Never remove the FD from the FDD, while it is being accessed.
