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.

the rear panel of the equipment to ground.
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 repr.esentative 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 parts.

DO NOT short the battery terminals and never attempt to disassemble it
or dispose of it in a fire. If the battery is damaged by any of these ac-

tions, the battery fluid may leak.

This fluid is poisonous.

DO NOT touch it, 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,
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.

3.

Use two or more people to lift and move this equipment. or use a trolley.

There is a risk of back injury, if this equipment is lified by one person.

4.

This equipment uses a lithium battery to back-up the memory. This bat­tery must be replaced by a servlce engineer when it has reached the end

of its useful life; contact the Anritsu sales section or your nearest repre­sentative.

NOTE:

5.

The main unit of the MP1777A uses lithium batteries. When d~sposing of
the batteries, make sure to conform with the local regulation.

The battery used in this equ~pment has a maximum useful life
of 7 years. It should be changed before this period has
elapsed.
