5. NAVTEX Reception and Decoding

When the unit is in the basic standby mode it will receive,

NAVTEX messages automatically when in reach of a

NAVTEX transmission station. However it is important to

know that:

during reception of other stations or when a stored

frequency is being received in the timer function, NAVTEX

cannot be received.

In order to obtain the best reception of NAVTEX

information, it is advisable to set certain system

parameters.

The input of the system parameters is carried out as follows:

x Press key to enter SETUP 1 menu

x Press key No. <2> to enter SETUP 2 menu

x Press key No. <3> to enter NAVTEX menu

5.1. Selection of the frequency

The FMD55 can receive all three international NAVTEX

frequencies at present available for NAVTEX:

518 kHz for coastal areas – messages in English

490 kHz for coastal areas – messages in local language

4209.5kHz for tropical areas – messages in English

x Press key <1> to enter <FREQUENCY> mode

x By using the cursors <UP> and <DOWN> you can select

one of the frequencies (490, 518, 4209.5 kHz). The

basic setting is 518 kHz. Fine tuning is not necessary

since the signal processor compensates minor

frequency deviation.

x To return to NAVTEX menu press <EXIT>.

The last frequency appearing on the display is now stored
