Limit acknowledge
The limit setting provides restricted use of the remote control func-
tion. It is useful when the following is desired:
• Automatically set a working channel when receiving an All Ships
call so as not to miss initial voice from the transmitting station.
• Prevent automatic transmission of acknowledge back (ACK BQ)
in response to an individual call, when no operator is present.
• Prevent automatic transmission of own ship position data in re-
sponse to an individual call which requests such data.
Auto acknowledge is automatically disabled when…
• An Error Checking Code (ECC) appears at the end of a receive
message.
• A distress alert is received. (A distress alert cannot be acknowl-
edged automatically.)
• Conducting voice communications.
