QUICK START
NAV-7 is extremely easy to operate:
• Apply power at the vessels power switch panel
• The NAV-7 will start up after a few seconds delay
• Set UTC time and date (automatic when connected to GNSS / GPS)
• The NAV-7 will now start to receive and display NAVTEX messages dependant
on the transmission schedule of the NAVTEX stations within the vessels current
region.
Note It may be several hours before the first message is received, this is dependant
on NAVTEX transmission coverage provided locally.
Take the time to read this manual carefully as it contains essential information
regarding the operation and maintenance of the NAV-7 and a useful background to
the NAVTEX system.

ABOUT NAV-7
The NAV-7 has been designed to meet the requirements of IMO (Intentional Maritime
Organisation) MSC.148 (77) and IEC technical standard 61097-6 (Ed 2.0).
The NAV-7 has three separate receiver channels, one each tuned to 490 kHz, 518
kHz and 4209.5 kHz. The NAV-7 will receive on all three frequencies simultaneously
in those parts of the world where transmissions are available (refer to Appendix 1).
The NAV-7 can be set up to filter out stations and/or message categories that are not
required by the User.
The NAV-7 is capable of being connected to an Integrated Bridge System (IBS),
transferring NAVTEX messages to other navigational aids if required. Note that the
IBS must be compliant with the serial port requirements of IEC 61097-6 (Ed 2.0).
The NAV-7 will accept UTC time & date information from the IBS port if available.
UTC time & date will be used to timestamp received NAVTEX messages.
Permanent installation of the NAV-7 can be made with either the bulkhead-mounting
bracket or the flush panel mounting kit provided.
The NAVTEX antenna should be mounted where it is elevated clear of metal objects
in a location where it cannot easily be damaged.
