10.  NBDP TRANSMISSION, RECEPTION

the coast station, a new answerback code must be entered. Contact FURUNO or an 
authorized FURUNO agent or dealer to enter a new answerback code.

The central system emits a free-signal to indicate a coast station radio channel is in 
idle condition and available for ship-to-shore calls. The free-signal is detected and rec-
ognized by the shipboard equipment as a permission to start the transmission. Then, 
the shipboard operator initiates a call.

You can automatically scan search for the free-signal by registering coast station radio 
channels in scan group(s). The procedure to register scan groups for coast station use 
is the same as that which appears in paragraph 8.5.1.

The next step is to enter station name. The procedure is the same as that shown in 
paragraph 8.3.1.

The following tables describe the commands for macro operation.
