USING THE TARGET NAVTEX V2.0

OPERATION.

When power is first applied the display will go to the end of the last 
message received. In the bottom left corner the words INT or NAT 
indicate the channel (International 518Khz or National 490Khz) the 
receiver is operating on. This is the STANDBY screen.            

To the right of the word STANDBY live incoming messages are streamed 
across the bottom of the screen.  The UP key lets you go back to earlier 
stored messages the DOWN key letting you scroll down the selected 
message. When in the body of a message the UP and DOWN keys 
allow scrolling through the message. At the start of a message the UP 
key moves you up to the previous message in memory. At the end of a
message the DOWN ket moves you down to the next message in 
memory. In the body of a message, pressing the ENTER key takes you 
to the beginning of that message. Pressing the ENTER key at the 
beginning of a message  takes you back
to the STANDBY screen.
Pressing any key turns on the screen backlight for a period of two 
minutes. N.B. When text is being written onto the screen a square 
character is shown at the top right. Whilst this character is displayed 
the keys are inactive.

PROGRAMMING
           
It is normal practice to program the navtex receiver to store only  the 
messages of interest to the user. To program the required STATIONS 
and MESSAGES first go to the STANDBY screen.  (Cont)
