Checking the antenna:
You may wish to check that the NAVTEX antenna position is suitable by inspecting
the signal strength during a known NAVTEX transmission from a local station.
Interpreting the diagnostics aids:
When a NAVTEX signal is being received, the appropriate receiver frequency icon
appears at the top of the display. If the
Monitor source
is set to this frequency then the
received data will appear in the
Monitor window
.
Use the
Receive icon,
Signal strength
bar and
Monitor window
to help diagnose
installation problems and/or as a check that your SMARTFIND GMDSS NAVTEX is
working correctly.

NAVTEX is used to indicate a new message or an active alarm
Key click
Allows key click sound to be disabled
Audible alarm
Allows the internal audible alarm to be disabled in installations
where the SMARTFIND GMDSS NAVTEX is not located at the main
navigation position of the vessel. Note that this setting does not
affect the operation of the integral alarm relay or the generation of
alarm sentences.

or confined to SAR messages only
Full font size
Offers three choices of message font size in Full Message view
NMEA checksums

Screen timeout
This setting allows the display to be automatically blanked after a
certain period of time. While the display is blanked, pressing any
key, or the receipt of a new message will turn it on again. Note that
this setting only affects the display screen; all the receivers in the
SMARTFIND GMDSS NAVTEX continue to work normally even
while the display is blanked.

Skip ext index
These fields allow the 4209.5 kHz or external receiver index pages
to be skipped in installations where the 4209.5 kHz receiver or the
external receiver are not used
WARNING
: Because messages are automatically deleted after 72 hours, changing
the time or date may cause stored messages to be lost.
