Scroll speed
Use this to set the scroll speed on the display. 
There is a choice of:  Very Fast, Fast, Me-

also affects the speed of the display.
Faster scroll speeds combined with a slow boat 
speed (typically between 2 and 6 knots) shows the 
most fish detail. Medium or Slow scroll speeds 
result in sonar information being displayed over a 
longer period, but with less detail. See Section 4-1 
Interpreting the display, for more information.
Fish symbols
These appear only in the main sonar displays. Fish 
symbols can be shown in three ways:
• 
As a fish symbol (On).
• 
As a fish symbol with the depth (On+depth). 
The depth is shown beside the fish symbol.
• 
Switched off (Off) so that echoes are not 
converted to fish symbols but are displayed 
directly.
See section 4-3 Fish detection and display, for 
more information about fish symbols.
Frequency
There is a choice of: 200 kHz,  50 kHz and
