Downloaded from https://www.everyspec.com request will be forwarded to USACESO (SFI-FAC-P, 200 Stoval St., Alexandria, VA 22332-2200) along with the DD Form 1494 and special justification. The justification must show that: (1) Eventual approval of the form can reasonably be anticipated. (2) Waiting the normal processing time may not be in the best interest of the Army. (3) As a result of coordination with the USACESO, it has been d e t e r m i n e d t h a t a n o p e r a t i n g f r e q u e n c y c o u l d b e a s s i g n e d . USACESO will forward the “Release of Funds Waiver” to the A r m y S p e c t r u m M a n a g e r ( S A I S - P A S - M ) f o r h i s s i g n a t u r e o f approval. b.
Exceptions. Exceptions to the requirements for submitting DD Form 1494 are limited to the following: (1) White Sands Missile Range (WSMR), NM; the Electronic Proving Ground (EPG), Fort Huachuca, AZ; Yuma Proving Ground (YPG), AZ; and Kwajalein Atoll (USAKA). These installations are part of the National Military Test Ranges operated under the respon- sibility of the Army. The DoD AFC WSMR, and the DoD AFC AZ, have allocation approval authority for all emitting and radiating equipment involved in range activities in their geographic areas. Equipment approved by the DoD AFC for use in support of range activities may or may not require a DD Form 1494.
The DoD AFC will independently decide on each equipment proposal. Approval by the DoD AFC does not assure that the form can or will be subsequ- ently approved for use in other geographic areas. (2) Incidental radiation devices. Exceptions are usually allowed for incidental radiation devices that radiate RF energy in the course of normal operation but are not designed to intentionally generate RF energy. Examples are clothes dryers, washing machines, electric typewriters, computers, and microwave ovens. These devices do not require a DD Form 1494 if the operating agency will either elimi- nate any harmful interference caused to an authorized radio service or obtain a waiver.
For this equipment, the waiver process is cov- ered by MIL-STD-481A, Paragraph 6.5. Waivers must be approved or disapproved by the local Materiel Review Board (MRB) or, in the absence of such MRB, the Contract Administrative Officer. c. Partial processing. The Army Spectrum Manager may approve some equipment for use without completing the Frequency Alloca- tion-to-Equipment Process, but only after the DD Form 1494 is submitted. This equipment is listed below: (1) Low power devices. Low power or restricted radiation de- vices as specified in the NTIA Manual. (2) Industrial, scientific, and medical (ISM) equipment. Radiation devices which use radio waves for ISM purposes.
Purposes include the transfer of energy by radio. ISM equipment will not be used for radio communication unless constructed and operated per the limita- tions defined in the NTIA Manual. (3) Ultrasonic equipment. Any equipment which generates RF energy and uses that energy to excite or drive an electromechanical transducer for the production of sonic or ultrasonic mechanical ener- gy. This energy is for ISM use and will not be used for radio or other communication purposes unless constructed and operated in accordance with the limitations defined in the NTIA Manual. (4) Lasers. Use of lasers for telecommunications is an area of considerable study and research.
In those instances where laser cod- ing techniques are used in range finding, target acquisition/identifi- cation research and development, or any other type of laser coding e x p e r i m e n t a t i o n t h a t w i l l l e a d t o s p e c t r u m o c c u p a n c y , m a t e r i e l developers must coordinate with the USACESO to determine if a DD Form 1494 is required. (5) Fuses and detonators. Items of materiel used solely to activate a fuse or detonator do not require a DD Form 1494. In some c o n g e s t e d a r e a s , c o n t r o l s m a y b e c o m e n e c e s s a r y t o a v o i d E M I caused by or to these devices.
In a noncombat situation, the opera- tion of such devices must not cause interference to authorized spec- trum users. Assistance and guidance in the selection of appropriate operating spectrum bands is available from the USACESO. (6) Commercial satellites. Satellites are registered by commercial companies and operate in commercial spectrum bands. A DD Form 1494 is not required. d. Radar design objectives and engineering criteria. The provi- sions of MIL-STD-469A and the NTIA Manual, Section 5.3, are mandatory for all new radars. However, existing radar systems and equipment will not be converted solely to comply with the require- ments of Section 5.3.
In any instance of harmful interference involv- i n g t h e u s e o f c o n f o r m i n g a n d n o n c o n f o r m i n g e q u i p m e n t , t h e activity using the nonconforming equipment will make adjustments to eliminate the interference. 4–7. EMC Standards for Telecommunications Equipment a. Categories. Certain military and national standards for fre- quency spectrum-dependent equipment should be reviewed before the DD Form 1494 is completed. Some of these major standards are shown in related references in Appendix A and in Table 4-2. The equipment limitations, as shown on the DD Form 1494, must be compared to these standards during the Frequency Allocation-to- Equipment Process.
Standards are in the following categories: (1) International standards and agreements. Many factors that influence standards, equipment operation, and design are related to international agreements. Some of these, such as international avia- tion agreements, affect worldwide operations. Others, such as the North Atlantic Treaty Organization (NATO) standardization agree- ments, affect C-E operations only in certain areas of the world. The ITU Radio Regulations (RRs) and the BR recommendations consti- t u t e t h e b a s i c i n t e r n a t i o n a l a g r e e m e n t s a f f e c t i n g s p e c t r u m management.
