Furuno FCV-30 - Manual (Page 21)

1. OPERATIONAL OVERVIEW
1-11
Note: Normally, pulses are fired from beam 1, beam 2 and beam 3 in that order and
displayed on the screen as the port, downward and starboard images. When the
display range of the 3-beam display is higher than 1000 m, the menu bar shows
“Simul. TX”. To fire pulses from beam 1 – 3 simultaneously click the Simul TX
indication to show ON. When this is done the picture advance speed quickens.
However, the display becomes susceptible to unwanted echoes. The default Simul
TX detection range is 1000 m. This value can be set between 100 and 5000 m. For
further details, see page 3-6.
