Owner’s Manual
Congratulations with your new Sirius-3 GMDSS Navtex receiver with
touch screen operations.
Safety Notices
Before installation please read the Installation Manual carefully.
The equipment must be 10-32 V DC powered only.
Do not open the Sirius-3 or the active antenna.
Unauthorized opening will invalidate the warranty.
The equipment is designed for operation in temperatures between
-15o C and +55o C. Do not use the Navtex receiver in temperatures
which exceed this range.
The Sirius-3 is waterproof from the front only.
A Navtex receiver is an aid to safe navigation and should not lead to
a reduction in the level of good navigation practice.
The propagation of radio signals may vary over time. No liability can
be accepted for the non reception of Navtex messages.
Connection to a source of UTC data to NMEA 0183 is recommended
for the best operation and automatic date-time information.

Sirius-3 Navtex 3-Frequency
About the Sirius-3 Navtex receiver
Your Sirius-3 has been designed to meet all requirements for use on
board a SOLAS convention vessel.
The Navtex receiver has three separate receiver channels, 490 kHz,
518 kHz and 4,209.5 kHz, for simultaneous reception of Navtex
messages.
It can be set up to filter stations and/or message types that are not
required by the user, however, some message categories at 518 kHz
are mandatory and can therefore not be switched off.
There is no on/off switch, as the equipment must always be turned
on, so that Navtex messages are received even in port.
If the equipment is installed with an external switch at the main
electrical switchboard, please, be sure that the equipment is turned
on at least one hour before departure.
The touch screen is the only Man-Machine-Interface.
It is designed for fingertip operation only.
Please, do not use sharp instruments when keying the buttons or
texts.
