in consideration of calling distance.
5. Put the cursor on "GO TO CALL," and then press the [ENTER] knob.
Transmission will be initiated.
6. Upon completion of transmission, the display will switch to the "WAIT FOR
ACK" window to wait for a response from the other party.
7. When receiving a response from the other party, a message saying "TEST
ACK received!" will appear on the window. Then, review the response
received and complete the test call.

minutes or more from the transmission, select a different frequency to make a
test call again.
Reference)
For test calls, it is recommended to monitor the ACK reception signal referring
to information on page 4-41. You can check communication state.
If no response from the other party, check for TX output power and frequency,
and change the frequency or Radio station.

Q69. I would like to know the procedure for conducting Test calls with NBDP.

A69. You communicate with a radio station handling public communications. When
you receive a response from the Coast radio station, you enter an automatic
response command such as "TEST+" or "HELP+" to receive a routine message.
Of course, you can call an operator with the "OPR+" command to communicate
with the operator. In this case, you should ensure the AAIC, CS, and Ship's name
beforehand because you will be asked by the operator for the registration with the
Coast radio station.
