4. The display begins to fade out. Images are not as sharp as normal.
Check the battery position and make sure that the battery door is properly closed. Also, make sure that you have removed
the plastic strip that is located in the battery compartment when it is new.
If this doesn’t help, replace the battery. After replacing the battery, if the unit still has a faded display, remove the battery
door again and re-install.
5. The display shows many black dots at high sensitivity settings.
You are seeing noise or interference caused by one of several sources. Noise can be caused by other electronic devices.
Turn off any nearby electronics and see if the problem goes away. Other sonar devices or any electronic device operating
in the 900 mHz range (in the 400 mHz range for International versions) could cause interference with your SmartCast.
6. The display shows fluctuating depth readings and excessive clutter, including vertical bars that may be
drawn on top of fish icons.
The SmartCast system comes with the capability to receive separate signals from a Channel A RSS or a Channel B RSS.
Two A- or B-type RSS units used simultaneously, as well as one A- and one B-type RSS unit used simultaneously, can
cause RF interference between each other.
7. The display jumps and the bottom has an abrupt change; sometimes a vertical line is missing or a black line
from top to bottom is displayed.
This display image jump is due to an automatic change in depth. New returns graphed at a different scale will not match
up with the historic data already graphed at a higher or lower scale. Vertical lines can also occur as the radio signal from
the RSS is lost and then regained in rough water conditions.
