EXTERNAL RECEIVER
The NAV-7 has the capability to receive from an external receiver (not supplied) on an
additional NAVTEX frequency should such an additional frequency be mandated by
the IMO in the future.
NAVTEX messages from the external receiver appear on the
View EXTERNAL
RECEIVER
page.
The external NAVTEX data must be presented as a stream of NMEA NRX sentences
as defined in Annex C of the IEC 61097-6 Ed.2 (2005) specification.
The external receiver may be another NAV-7; in such a case, a single antenna may
serve several displays. For more information, contact your dealer or the McMurdo
Customer Service team.
MAINTENANCE GUIDE
General Points to Check
•
Periodically make sure that the antenna connector is well sealed and that there
isn’t sign of corrosion around the PL259 connector
•
Make sure connections to the back of the NAV-7 display are secure
