is being sent, the TX/BUSY indicator will grow red.

between Channel 16 and Channel 70 until an acknowl-
edgment signal is received. The display will be shown
in the illustration on the right.

repeated in 4 minute intervals until an acknowledgment
is received.

and channel 16 is automatically selected. The display shows the MMSI of
the ship responding to your distress.
