8. Troubleshooting
Below is a table of common problems and solutions, but if you have a problem that cannot be solved from the
table below, or an issue that is not covered, please contact StarFish technical support.
Note: For software issues and problems, please refer to the “Scanline User Guide”.
Problem… Solution(s)…
Electrical interference This is most commonly seen as bright small snow-like dots over the image –
usually with some form of regular repeating pattern.
The most common cause is interference from other high-current switching
electrical devices (such as mains inverters, or motors) connected to the same
power source as the top box electronics module.
Try methodically turning off other electrical devices to find the cause, or
running the StarFish from its own dedicated supply (or battery).
Acoustic noise This is most commonly seen as large stripes or pulses of varying brightness
over the image, usually with some form of regular repeating pattern.
Try to identify and, where possible, remove the source of the acoustic noise.
Most commonly, your platform, or other vessels, may have an echo-sounder
that is running at a frequency close to the operating band of the StarFish.
Image ghosting or mirroring
This problem may occur if the StarFish transducers are receiving echoes
from features on the hull/platform it is mounted on.
Try repositioning the transducers so the acoustic beams are not obstructed
from the transmitter faces.
This problem can also occur in shallow water, where the high-intensity
transmission from one transducer is being received by the other. If possible,
use the software to display only a single channel (and prevent transmissions
from the other); this will reduce the inter-channel cross-talk.
