(supplied) and then plug this into the socket labelled NAVTEX on the
interface lead supplied with the radio(see Fig.1).

power source to power the NAVTEX antenna (see Fig.2).
USING THE SILVA NAVTEX WITH AN S15 VHF RADIO.
If you are using the SILVA NAVTEX antenna in conjunction with the
SILVA S15 VHF radio all you need to do is make a simple plug and
socket connection. Selection of stations and message types are carried
out on screen. See S15 owner’s manual for details.
When you switch on the power to your S15 radio for the first time you will
hear a double beep and a NAVTEX test message will be displayed on the
NAVTEX screen. This is confirmation that the system is operational. (see
below):
To view the contents of the NAVTEX test message, please go to the
NAVTEX log, displayed as below:
If you erase this message it will reappear next time you switch on – If you
don’t, it will see that that message has been received before and ignore it.
This is a general feature of the system in order to conserve message
storage space it only records each message once and will ignore any
subsequent repetitions (unless you erase the original). Select frequency
(518/490khz) by means of the inline ‘slide switch’ supplied.
