in accordance with the CCIR Recommendation 540 as specified in 
Sec. 80.1101.
    (c) Maritime safety information is transmitted by means of narrow-
band direct-printing telegraphy with forward error correction using the 
frequency 518 kHz in accordance with the international NAVTEX system 
(see Sec. 80.1077).
    (d) The frequency 490 kHz may be used, after full implementation of 
the GMDSS, for the transmission of maritime safety information by means 
of narrow-band direct-printing telegraphy with forward error correction 
(see Sec. 80.1077).
    (e) Internationally, the frequency 4209.5 kHz is used for NAVTEX-
type transmissions by means of narrow-band direct-printing telegraphy 
with forward error correction (see Sec. 80.1077).
    (f) Maritime safety information is transmitted by means of narrow-
band direct-printing telegraphy with forward error correction using the 
frequencies 4210 kHz, 6314 kHz, 8416.5 kHz, 12579 kHz, 16806.5 kHz, 
19680.5, 22376 kHz, and 26100.5 kHz (see Sec. 80.1077).
    (g) Maritime safety information is transmitted via satellite in the 
maritime mobile-satellite service using the band 1530-1545 MHz (see 
Sec. 80.1077).
