Local Channel; Rcv Mask - Furuno NX-700B Service Manual

3. Local Channel

This is the setting which local frequency, 490 kHz or 4209.5 kHz, should be received.
When "INS" is selected in [MENU] -> NAVTEX -> Mask Mode, this setting item is
not displayed.
When "4209.5 kHz" is selected, the Auto mode is not enabled on this frequency even if
"On" is selected in [MENU] -> NAVTEX -> Rcv Mask. It is because the service area is
not consistent due to the feature of HF radio wave propagation.
