– 127 (turning left at 720 degrees per minute or higher)
5.4 Restarting the NAUTICAST™
The NAUTICAST™ could be restarted during operation by pressing the keys
“Shift” + “Fn” + “Del” simultaneously. It could take up to 6 minutes to receive all information from
other ships again because of their reporting interval.
