In the DC scenarios, WIFCOM hand-heldtransceivers are issued to the investigators and sceneleader. They are the primary means of communication inthe repair station area of responsibility. The 21J (or otherdesignated) sound-powered telephone circuits are theprimary means of communication between repair lockersand DCC. Personnel using WIFCOM must be aware ofspecific zones of reduced transmission capability or deadzones. Secondary communications, such as messenger orvia second WIFCOM operator, must be used tocommunicate through dead zones. If emission control isnecessary, special consideration must be givenWIFCOM. In watertight areas during material conditionZEBRA, WIFCOM transmissions may be interrupted.These transmissions can be made only with commandapproval. In case of WIFCOM failure, repair lockerpersonnel should establish effective communications asquickly as possible using other methods.REVIEW 6 QUESTIONSQ1. Your phone system is unsecured.

They have identified nations,governments, rank, and ownership and have conveyedmessages for centuries. This section introduces flagsand pennants that identify persons and ships andtransmit information and orders. On special occasions,flags are used as a decoration, such as “dress ship.”The Navy uses the international alphabet flags;numeral pennants and a code/answer pennant; a set ofnumeral flags, special flags, and pennants; and foursubstitutes, or repeaters.Each alphabet flag has the phonetic name of theletter it represents. A numeral flag takes the name of thenumeral it represents; numeral pennants are used onlyin call signals. Special flags and pennants are used intactical maneuvers to direct changes in speed, position,formation, and course; to indicate and identify units;and for specialized purposes. Flags and pennants arespoken and written as shown in figures 4-14 and 4-15.4-17Student Notes:
