Chart Speed
Chart Speed control how fast the sonar information moves across the screen. With the high
speed, you could see more information across the screen; however the fast moving
information makes you feel difficult to interpret the fish details and bottom.
With the low speed, you feel easeful to have enough time to interpret the fish details and
bottom. However the compressed information may cause a little problem for you to
interpret them.
To achieve better images, try adjusting the Chart Speed level to match how fast you are
moving in the actual condition: stationary, drifting slowly or running you boat at different
speed.
To set the Chart Speed:
1) Press Menu to enter into the menu
setting.
2) Use the Up / Down Arrow to select
Sonar Option.
3) Press Right Arrow to enter into
Sonar setting.
4) Use the Up / Down Arrow to select

5) Press Right / Arrow to enter into

7) Press Ent to confirm the setting.
8) Press Exit to exit from the menu
setting.
Noise Filter
Noise Filter is used to filter the noise from the air or water environment to get a clear
sonar image on the screen.
In many situations, your Fishfinder display will be effected by undesired signal which
maybe caused by your boat engine, turbulence, wiring, or other electrical and mechanical
sources.
