CALIBRATION VOID IF SEAL BROKEN.-

The CALIBRATION VOID IF SEAL BROKEN label (fig. 13-20, black letters with a white background) is placed over readily accessible (usually exterior) adjustments to prevent tampering by the user when such tampering could affect the calibration. The label should not be used to cover adjustments or controls that are part of the normal use or operation of the instrument. This label may also be used to prevent removal and/or interchange of plug-ins, modules, and subassemblies when such removal or interchange will affect the calibration.

Repair of Test/Measuring Equipment

Test equipment corrective maintenance is the correction of test equipment troubles, including the repair of an item after a complete breakdown, finding of faults during preventive maintenance, or the tuning and adjustment of an item to restore it to operating condition.

Many fleet activities are reluctant to repair electronic test equipment. However, the Navy expects fleet personnel to perform a certain amount of maintenance and repair of their own test equipment whenever possible. The parts needed to make repairs may already be aboard the ship. It will often be your responsibility to decide when a piece of test equipment should be repaired and who should repair it. You will need to consider the following factors.

Much of the test equipment now being used by naval activities is expensive and is built and calibrated to a high degree of precision. Repair often requires special laboratory facilities and skill. Although each activity should accomplish all repairs within its capabilities, the lack of qualified personnel or adequate facilities limits the kinds of repairs each activity should attempt. Repairs attempted by unqualified maintenance personnel or personnel working in inadequate facilities could result in extensive damage to equipment. Therefore, you should evaluate each piece of test equipment to determine if your personnel should make the repairs, especially when maintenance of test equipment requires repair of critical calibration or frequency-determining circuits. When repairs are accomplished locally, technical manual procedures should be followed carefully; the repair and assembly of parts should be meticulous. When your personnel cannot make the repairs or when the necessary post verification is beyond the capabilities and facilities of repair personnel, the equipment should be forwarded to the nearest maintenance activity that has the proper facilities.

Calibration laboratories are authorized to make only incidental repairs, defined as those found necessary during calibration to bring the item within specified tolerances. Before submitting an inoperative item of test/measuring equipment for repair to the maintenance activity, you should note all faults, symptoms, and any other malfunction characteristics on an OPNAV Form 4790/2K and submit the 2K through the proper channels for repair-action screening.

PHYSICAL SECURITY OF CLASSIFIED MATERIAL

LEARNING OBJECTIVE: Discuss the aspects of physical security of GM spaces and classified material.

It is the responsibility of all personnel in the Navy to safeguard military information. Since you may often require the use of classified matter in your work, an understanding of the proper safeguards and control of such matter is essential.

The Department of the Navy Information Security Program Regulations, OPNAVINST 5510.1 (latest revision), is the controlling guide in safeguarding classified information. There is no adequate substitute for continuous day-to-day practice in the proper methods of handling classified material.

Classified information or material may be used only where the proper control facilities are available or under conditions adequate to prevent unauthorized persons from gaining access to it. The exact nature of security requirements depends on a thorough security evaluation of local conditions and circumstances. Security requirements must permit the accomplishment of essential functions while affording classified information appropriate security. The requirements that follow represent the minimum acceptable standards.

RESPONSIBILITIES OF CUSTODIANS

Custodians of classified material should be responsible for safeguarding the material at all times, and particularly, for locking classified material in appropriate security containers whenever it is not in use or under the direct supervision of authorized persons. Custodians should follow procedures which ensure that unauthorized persons do not gain access to classified information or material by sight or sound or other means. Classified information should not be discussed with, or in the presence of, unauthorized persons.

Classified information or material should not be removed from an officially designated office or working area for the purpose of working on such material during off-duty hours. Holding classified material for purposes involving personal convenience is not authorized unless specifically approved by the commanding officer or his or her designee. Prior to approval being granted, it must be determined that a compelling necessity exists, the required physical security can be provided, and a complete list of the removed material will be left with the command.

CARE OF WORKING SPACES

Buildings and spaces containing classified information must be afforded the security measures necessary to prevent unauthorized personnel from gaining access to it. 'This includes the security measures necessary to prevent persons outside the building or spaces from viewing or hearing classified information.
