This symbol is overlayed over a target to indicate the target is "lost". No AIS data
has been received from the target within the expected interval or 10 minutes for
targets that haven't reported their position. The expected interval is based on AIS-
specified transmission intervals and determined by AIS class and speed.
A circle appears around a target that is marked as a member of your “fleet”.
Display is oriented North-Up for this profile. Use setup to change the default
orientation or the orientation associated with the current profile. If this symbol is not
displayed, then the display is oriented Heading-Up.
Indicates your AIS data is not being transmitted. In order for your AIS data to be
transmitted you must have configured the MMSI and the GPS must have a position
fix. Other reasons are silent mode has been enabled or a base station has
commanded your AIS transceiver to enter “quiet mode”. You can use the
AIS Status
screen to determine the reason.
Important:
The
AIS
WatchMate
will not begin to transmit for one minute after it has
been switched on. This startup time is required to determine background noise
levels on the AIS frequencies. During this time, the warning symbol will be shown.
When used with a Vesper Marine AIS/VHF antenna splitter this symbol indicates the
VHF radio is in-use and AIS transmissions are temporarily disabled.
