Northstar 8000i Operation Manual
42 Troubleshooting
42.1 Touch screen is inaccurate
If you've having problems selecting items by touch on the display screen, try
calibrating the touch screen; (see "Calibrate the touch screen" page 190)
42.2 Camera screen goes blank or camera isn't available
If the Camera screen suddenly goes blank, or if you get a message saying that the
camera isn't available, it's likely that the camera has been disconnected.
To reconnect the camera:
1. If the Camera screen just went blank, leave this as the active pane on
the 8000i.
2. Physically check that all the camera cables are connected. If so, check
that the connections are tight. When the camera is reconnected, the
8000i automatically detects it again.
3. The video feed is resumed and the picture is displayed again.
42.3 Sounder - Bottom is not displayed
There are two possible reasons why the bottom may not be shown:
•
The sounder range mode may be set to Auto Range Off, and the selected
Range is set too high to show the bottom. Either change the sounder to Auto
Range On, (see "Turn the auto range on or off" page 117) , or manually
select a range shift that will include the bottom; (see "Change the range shift"
page 118) .
•
The bottom may be too deep for the sounder to detect. If you have Auto
Range On, the sounder will flash the last depth detected, then display "--.--"
to indicate there is no bottom detected. The bottom should re-appear on the
screen when it becomes shallower than 600 ft (180 m).
42.4 Sounder shows a double bottom trace
If you're seeing a double bottom trace, it's possible that:
•
your vessel is in an area that generates shadows (see "How to recognize and
avoid shadows" page 113).
•
your vessel is in shallow water and the echoes are bouncing. Try reducing the
gain setting (see "Change the gain setting" page 115).
