MESSAGES
The following are descriptions of messages that may be displayed.
FIS ALERT, NO VALID
FIS SUBSCRIPTIONS
The message shown in
Figure 106 would indicate
that no subscriptions have
been set up or previously
entered subscriptions have
expired or will become valid
at a future date. This is the
only indication received when
an XM WX subscription has
expired.
NO DATA RECEIVED
FROM FIS RECEIVER
If the KMD 550/850 display is
unable to communicate with
the KDR 510 VDL Receiver
or the KDR 610 XM
Receiver, a message such
as that shown in Figure 107
will be displayed.
If this message persists, it
may indicate a problem with
the Receiver or the wiring
between the KDR 510/610
and the KMD 550/850.
(PRODUCT) NOT
AVAILABLE, DATA
NOT RECEIVED
If no valid graphical FIS data
is received, a message such
as the NEXRAD Image
product example in Figure
108 will be displayed.
This message usually means that the system is not in FIS VDL cov-
erage, or the XM WX signal strength is poor.
The message can also occur while in coverage if not all of the data for a
weather product has been received.
