acknowledge the signal, do so by hoisting the signal close   up,   bearing   in   mind   the   ship's   visual responsibility.  This  notifies  the  originator  that  your ship understands the signal and is ready to carry out any required action. When the originator lowers the hoist, haul down your hoist smartly and inform the OOD that the signal has been hauled down. When  an  addressee  desires  to  question  a  signal, the signal or ANS shall be kept at the dip, and the INTERROGATIVE  pennant  hoisted  on  an  adjacent halyard. Normally, an address over INT will not be required when communication is only between the originator  and  the  addressee  questioning  the  signal. When necessary to refer to the signal of a specific originator, a call may precede INT. NOTE INT signals need not be acknowledged if the  signal  in  question  can  be  clarified, hoisted, or canceled immediately. However, when answered and brought close up on both ships, INT signals should be hauled down to free the halyards for additional signals. In addition to the provisions for the use of the INTERROGATIVE pennant used alone, it may be amplified and used as follows: INT l—Signal now flying not distinguishable. INT 2—You are repeating signal incorrectly. INT 3—I am repeating signal incorrectly. These signals are most effective in expediting flaghoist signaling when passed by flashing light. Once a problem has been identified, regardless of ship (be it the originator, repeating ship, or last ship in visual  chain  of  responsibility),  adherence  to  the procedures for canceling or correcting a hoist are of paramount importance in avoiding early execution or delay and/or confusion in the receipt of the intended signal. Requests may be acknowledged by a senior officer by hoisting flag CHARLIE or NEGAT below the call of the ship making the request. Such signals constitute both receipt and answer. CANCELING A SIGNAL Flaghoist  signals  are  canceled  by  the  following uses of NEGAT: 5-14 When only one flag signal is flying, NEGAT hoisted on an adjacent halyard cancels the signal. When two or more flag signals are flying under the same call, NEGAT hoisted on an adjacent halyard cancels all signals flying. If only one signal is to be canceled, it must be repeated preceded by NEGAT. When   “all   ships”   signals   and   specifically addressed signals are flying at the same time, NEGAT without a call preceding it cancels all signals without a call, and NEGAT with a call preceding it cancels all signals under a similar call. If only one signal of several signals under the same call is to be canceled, it must be repeated and preceded by NEGAT under the same call. The canceling signal and the signal canceled are to be hauled down together when all addressees have acknowledged. CORRECTING A SIGNAL Flaghoist signals are corrected as follows: An originating ship cancels the signal in question, then hoists the correct signal. A repeating ship hoists the signal meaning “Signal is repeated incorrectly” on an adjacent halyard, then hauls down both signals. The correct signal is then hoisted. EXPEDITING OF FLAGHOIST SIGNALING An  originating  ship  may  pass  its  signal  by  flashing light if there is doubt that its flags can be seen clearly. Directional or non-directional light, using proper procedure, can be used. The operating signal ZJL meaning “Hoist the following signal” can be included. Directional If directional procedure is used, the signal will be receipted for by light and acknowledged in the normal flaghoist manner. The executive signal need not be made by light when the signal is hauled down. Non-directional If non-directional procedure is used and no ship will answer, the signal may be repeated as often as necessary, with repetitions being separated by the prosign IMI. Ships will acknowledge by flaghoist. The
