Furuno FCV-30 - Manual (Page 74)

3. CHANGING SETTINGS
3-6
Color resolution: Effective when “Clutter curve” is turned off. You may set display width dB
for colors. Set display width dB for one color.
Line interpolation: Smoothes picture when picture advance speed is 2/1, 4/1 or 8/1.
Echo smoothing: When echoes look “spotty”, adjust this setting. The higher the setting the
greater the smoothing.
Ping setting: Chooses source of keying pulse, external (for use only when external echo
sounder is used) or internal.
Bottom search: Turns bottom detection feature on or off. When turned off, “-.-“ appears as
the depth indication in the status window.

Multi beam dialog box description
TX frequency: Sets Tx frequency, and the choices are Low, Standard and High. For normal
use, choose Standard. When interference exists because your vessel is near another vessel
whose echo sounder operates on the same frequency as the FCV-30, choose Low or High
as appropriate to remove this interference.
TX pulse width: Pulse width is automatically changed with display range and shift. A
shorter pulse offers better resolution, while a longer pulse is useful for long-range detection.
Choose Standard for general sounding; Long, for longer detection range (about twice that of
the Standard setting).
