    116 Administrations are urged to authorise the use of the band 3 155–3 195 kHz to provide a common worldwide channel for low power wireless hearing aids. Additional channels for these devices may be assigned by administrations in the bands between 3 155 kHz and 3 400 kHz to suit local needs.

     It should be noted that frequencies in the range 3 000 kHz to 4 000 kHz are suitable for hearing aid devices which are designed to operate over short distances within the induction field.

    117 Alternative allocation:  in Côte d'Ivoire, Egypt, Liberia, Sri Lanka and Togo, the frequency band 3 155–3 200 kHz is allocated to the fixed and mobile, except aeronautical mobile, services on a primary basis.     (WRC-19)

    118 Additional allocation:  in the United States, Mexico and Peru, the frequency band 3 230–3 400 kHz is also allocated to the radiolocation service on a secondary basis.     (WRC-19)

    119 Additional allocation:  in Peru, the frequency band 3 500–3 750 kHz is also allocated to the fixed and mobile services on a primary basis.     (WRC-15)

    122 Alternative allocation:  in Bolivia, Chile, Ecuador, Paraguay and Peru, the frequency band 3 750–4 000 kHz is allocated to the fixed and mobile, except aeronautical mobile, services on a primary basis.     (WRC-15)

    123 Additional allocation:  in Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Zambia and Zimbabwe, the frequency band 3 900–3 950 kHz is also allocated to the broadcasting service on a primary basis, subject to agreement obtained under No. 9.21.      (WRC-19)

    125 Additional allocation:  in Greenland, the band 3 950–4 000 kHz is also allocated to the broadcasting service on a primary basis. The power of the broadcasting stations operating in this band shall not exceed that necessary for a national service and shall in no case exceed 5 kW.

    126 In Region 3, the stations of those services to which the band 3 995–4 005 kHz is allocated may transmit standard frequency and time signals.

    127 The use of the band 4 000–4 063 kHz by the maritime mobile service is limited to ship stations using radiotelephony (see No. 52.220 and Appendix 17).

    128 Frequencies in the frequency bands 4 063–4 123 kHz and 4 130–4 438 kHz may be used exceptionally by stations in the fixed service, communicating only within the boundary of the country in which they are located, with a mean power not exceeding 50 W, on condition that harmful interference is not caused to the maritime mobile service. In addition, in Afghanistan, Argentina, Armenia, Belarus, Botswana, Burkina Faso, the Central African Rep., China, the Russian Federation, Georgia, India, Kazakhstan, Mali, Niger, Pakistan, Kyrgyzstan, Tajikistan, Chad, Turkmenistan and Ukraine, in the frequency bands 4 063–4
