COMMUNICATIONS NAVSEA 0967-LP-000-0010 PREFACE

POLICY AND PURPOSE

The Electronics Installation and Maintenance Book (EIMB} was established as the medium for collecting; publishing, and distributing, in one convenient source document, those subordi­nate maintenance and repair policies, installa­tion practices, and overall electronic equip­ment and material-handling procedur·es required to implement the major policies set forth in ChaptP.r 400 of the Naval Ships' Technical Manual. All data contained within the EIMB derive their authority from Chapter 400 of the Naval Ships' Technical Manual, as established in accordance with Article 1201 , U.S. Navy Regulations.

Since its inception the EIMB has been expanded to include selected information of general interest to electronic installation and maintenance personnel. These items are such as would generally be contained in text­books, periodicals, or technical papers, and form (along with the information cited above) a comprehensive reference document. In appli­cation, the EIMB is to be used for information and guidance by all military and civilian personnel involved in the installation, main­tenance, and repair of electronic equipment under cognizance, or technical control, of the Naval Sea Systen� Command (NAVSEA). The infonnaHon, instructions, and procedures, in the EIMB supplement instructions and data supplied in equipment technical manuals and other approved maintenance publications.

INFORMATION SOURCES

Periodic revisions are made to provide the best current data in the EIMB and keep abreast of new developments. In doing this, many source documents are researched to obtain pertinent information. Some of these sources include the Electronics Information Bulletin (EIB), the NAVSEA Journal, electronics and other textbooks, industry magazines and peri­odicals, and various military installation and maintenance-related publications. In certain cases, NAVSEA publications have been incorpo­rated into the EIMB in their entirety and, as a result, have been cancelled. A list of the documents which have been superseded by the EIMB and are no longer available is given in Section 1 of the General Handbook.

ORIGINAL xiii

ORGANIZATION

The EIMB is organized into a series of handbooks to afford maximum flexibility and ease in handling. The handbooks are stocked and issued as separate items so that individ­ual handbooks may be obtained as needed.

The handbooks fall within two categories: general infonnation handbooks, and equipment­oriented handbooks. The general information handbooks contain data which are of interest to all personnel involved in installation and maintenance, regardless of their equipment specialty. The titles of the various general information handbooks give an overall idea of their data content; the General Handbook includes more complete descriptions of each handbook.

The equipment handbooks are devoted to infonnation about particular classes of equip­ment. They include general test procedures, adjustments, general servicing information, and field change identification data.

All handbooks of the series are listed below with their STOCK

numbers.

DISTRIBUTION

Initial Set: An "AF" Restriction Code has been assigned to NAVSEA 0967-LP-000-0000 to control the over-requisitioning of the EIMB Series. Fleet and shore activities requiring an initial set of the EIMB Series ( 1 3 hand­books with all changes and heavy-duty binders) should submit their requisition (DD Form 1348 with written justification) through their Supply Officer or area, for issue approval to:

Commander Naval Sea Systems Command SEA 05L32 Washington, DC 20362

Use the following data on the DD- 1348,

Block A - 288 NAVPUBFORMCEN PHILA Stock No. - �967-LP-000-0�00 Unit of Issue - SE Fund - "0

All other blocks are to be filled in as normally done by the requisitioner when order­ing publications.

Chan�es and Revisions: The EIMB is contin­uously efng updated. For efficiency these changes and revisions are automatically dis­tributed to using activities who are on the Automatic Distribution List for the EIMB.

Requests and/or changes to the EIMB Auto­matic Distribution List and any problems in requisitioning should be directed to:

Commander Naval Sea Systems Command SEA 05L32 Washington, DC 20362

Individual Handbooks: To order individual handbooks and changes, use the stock numbers listed in the Box Score on page ft. Using the stock number for the "BASIC" provides the handbook (with vinyl cover) and all applicable changes.

SUGGESTIONS /CORRECTIONS

NAVSEA recognizes that users of the EIMB will have occasion to offer corrections or suggestions. To encourage more active parti­cipation, a pre-addressed comment sheet is provided in the back of each handbook change. Complete information should be given when preparing suggestions. Suggestors are encour­aged to include their names and addresses so that clarifying correspondence can be initiated when necessary. Such correspondence will be by letter directly to the individual concerned.

If a comment sheet is not available, or if correspondence is lengthy, corrections or sug­gestions should be directed to the following:

Commander Naval Sea Systems Command SEA 05L32 Washington, DC 20362
