1 Scope
NOTE 1 In Annex D, information is included on infra-red radiation in the wavelength range 0,7 µm to 1,6 µm.
NOTE 2 Sources of power may include, for example: the public low-voltage supply; private supplies with similar characteristics; a d.c. source provided specifically for the apparatus; batteries internal to the apparatus; stand-by generators. Some standards may not apply to private low-voltage supplies.
NOTE 3 In special cases, for instance when highly susceptible apparatus is being used in proximity, additional mitigation measures may have to be employed to reduce the electromagnetic emission further, below the specified levels.
NOTE 4 Professional-user receiving apparatus may be very sensitive to disturbance; see Annex E.
-
- consumer apparatus,
-
- apparatus specifically designed for security systems, and
-
- apparatus designed to radiate electromagnetic energy for radio communications purposes.
NOTE 5 To ensure freedom from interference, manufacturers should consider the characteristics of other equipment likely to be in the same environment and thus determine whether limitation of emissions in additional frequency ranges is necessary.
