and requires little maintenance. To learn how to
operate an electronic calculator, you will need
instruction from an experienced operator or
company representative.
WARNING
To prevent electrical shock, never operate
any calculator without ensuring that the
machine is grounded. Have a qualified
electrician check the grounding connec-
tions. Do not use a calculator during severe
electrical storms, while standing or sitting
with your feet on a wet deck, or with wet
hands.
Care and Maintenance
All calculators are precision instruments and
must be protected from bumps and jars that will
upset the delicate balance of their mechanism. As
with other office machines, dust and dirt are big
enemies. Keep your calculator clean and covered
when not in use. If the machine is not operating
properly, immediately unplug it. Do not attempt
to repair calculators yourself. All repairs and
maintenance should be done by qualified
technicians or company representatives. Because
of its solid state, the electronic calculator requires
little maintenance other than the replacement of
the projector tube.
DUPLICATING MACHINES
There used to be three types of duplicating or
reproduction machines used throughout the Navy.
The AZ was expected to be familiar with and to
operate each type. The three types of duplicating
machines that used to be found in maintenance
activities were the photocopier, the Mimeograph,
and the Ditto. The Mimeograph and the Ditto
machines have since become outdated and too
expensive to operate. The photocopier is widely
used within all naval activities. As an AZ, you
will be expected to know how to operate a
photocopier.
Photocopier machines provide the easiest
means of reproducing copies of documents. To
zerox (as it is commonly referred to) is the process
of reproducing copies on a photocopier machine.
This process is relatively expensive; therefore,
when many copies are required, it may be
advantageous to use another duplicating process,
considering typing time required and other
factors. There are several models of photocopier
machines available, but they are alike in most
respects.
Manufacturers instruction manuals or sheets
furnish operator information on their particular
models. You should be properly indoctrinated by
qualified personnel before operating photocopier
machines.
OFFICIAL CORRESPONDENCE
In this section of the TRAMAN, the correct
handling and routing of official mail (classified
and unclassified) is discussed. The correct
procedure for marking classified mail and
preparing it for mailing; along with security of
correspondence in the files, is discussed later. For
detailed information concerning the security of
classified information (which is required of all
petty officers), you should refer to the latest
edition of Department of the Navy Information
and Personnel Security Program Regulation,
OPNAVINST 5510.1.
CLASSIFICATION AND SECURITY
Because AZs handle mail and publications,
you will need to know about classified informa-
tion. You will not handle classified information
unless you have been authorized to do so by the
commanding officer, and then only when there
is a reason for you to do so. However, you should
know the categories of classified matter and
security rules.
Before handling of incoming and outgoing
mail is discussed, several principles are described
that affect all procedures concerned with docu-
ments of certain categories.
Transmission of Classified Matter
Top Secret matter is transmitted by personal
contact of the persons concerned, by the Armed
Forces Courier Service, or by electric means in
encrypted form. This category is never transmitted
by registered mail or handled by regular routing
procedures.
Secret and Confidential matter may be
transmitted by registered mail or by any of the
means approved for Top Secret. The AZ will be
concerned chiefly with its transmittal by registered
mail.
Material designated as Confidential requires
modified handling and may be sent by ordinary
