* 1 DSC operation only.
* 2 Channels 15 and 17 may also be used for on-board communications provided the effective radiated power does not exceed 1
W, and subject to the national regulations of the administration concerned when these channels are used in its territorial waters.
* 3 UK Marina Channels: M1=37A (157.850 MHz), M2=P4 (161.425 MHz) for U.K. version only
* 4 The output power of channels 75 and 76 are limited to low power (1 W) only. The use of these channels should be restricted
to navigation-related communications only and all precautions should be taken to avoid harmful interference to channel 16,
e.g. by means geographical separation.
