What to do if there is no picture on my Simrad EQ33 Marine Equipment display screen?
If there is no picture on the display screen, first, press the [PWR] key on the keypad. If that doesn't work, replace the fuse, ensuring you use only a 4.0A slow type fuse.
Why is there no normal picture or key operation on my Simrad EQ33 Marine Equipment?
If you're experiencing a lack of normal picture or key operation, try turning the unit off and then on again. If that doesn't resolve the issue, disconnect the power and then reconnect it. You may also return to factory presets, see section 7.7.
What to do if echo picture appears normal, but no targets are shown on Simrad Marine Equipment?
If the echo picture appears normal but no targets are shown (or only random noise is visible), go to the Echosounder setup and select the appropriate transducer frequency. Also, ensure that the connectors are correctly mated to the unit. Additionally, try increasing the receiver gain in the 5.9 Presentation setup and adjusting the range in the 5.9 Presentation setup.
What to do if picture is too dark or bright on Simrad EQ33?
If the picture appears on the display screen but is either too dark or too bright, press the [PWR] key, adjust the light/contrast settings, and then press the [ENT] key.
Why is all data deleted after turning off Simrad Marine Equipment?
The internal battery must be replaced by authorized dealer. The expected lifetime is min. 5 years.
How to reduce excessive noise in echo picture on Simrad EQ33 Marine Equipment?
To reduce excessive noise in the echo picture, ensure that all connected equipment is properly grounded to the main unit.
