Send NAVTEX
In this mode the test box can send a NAVTEX test message on 490 kHz, 518 kHz or 4209.5
kHz to a NAVTEX receiver in order to check the NAVTEX receiver/printer.
Connect the wire antenna supplied with the test to RF OUT. Select SEND NAVTEX and
frequency, and press OK to send the NAVTEX test message.
If the signal is not strong enough to enable the test, you may connect the RF Amplifier (optional
accessory) as shown below.
Two different NAVTEX messages are being sent – a navigational warning and a SAR message.
Check that the NAVTEX receiver prints the following messages:
NAVTEX MESSAGE XA00
0123456789ABCDEFGHIJKLMNOPQRSTU
NAVTEX TEST SEQ BY FUTRONIC
GMDSS TEST BOX
NAVTEX MESSAGE XD00
0123456789ABCDEFGHIJKLMNOPQRSTU
NAVTEX TEST SEQ BY FUTRONIC
GMDSS TEST BOX
SECOND TIME
X = Transmitter ID, A = Navigational warning, D = SAR message, 00 = Message No
Please note that the NAVTEX receiver may have been set to neglect routine messages with a
transmitter ID letter and message number already received within a certain period of time. If so,
a test message from the test box may also be neglected by the receiver.
