To perform a soft reset, turn off the unit. Then, press and hold the PAGES key while turning the unit back on. Release the key when the unit powers up. This will reset settings without deleting your stored data.
Ensure that the transducer is properly connected and submerged in water. Check for any damage on the transducer cable. Additionally, make sure that the unit is set to the correct depth range and that the keel offset is properly configured.
Visit the Lowrance website to check for available updates. Download the update to an SD card. Insert the SD card into the unit and follow on-screen instructions to complete the update process.
Try performing a soft reset. If the issue persists, check the power connections and the battery voltage. Ensure that the connectors are clean and secure.
Ensure that the external GPS antenna has a clear view of the sky. Avoid obstructions like metal structures. Regularly update your unit's software and check for any available GPS module updates.
Press the MENU button twice and use the arrow keys to select the SONAR tab. Adjust the sensitivity to match your fishing environment, keeping it high enough to detect fish but not so high that it shows excessive noise.
Use a soft, damp cloth to clean the screen and exterior. Avoid using harsh chemicals or abrasive materials. Regularly inspect and clean the connectors to ensure a good electrical connection.
Press the WPT button, then select the ‘Save’ option. Enter the name and details of the waypoint, then select ‘Save’ to store it in the unit’s memory.
Clutter can be caused by high sensitivity settings, interference from other electronics, or air bubbles. Adjust the sensitivity, check for interference, and ensure the transducer is clean and properly positioned.
Fish arches appear when fish pass through the sonar cone, while solid lines indicate the bottom. Use the color scale to differentiate between harder and softer objects. Adjust the sensitivity for clearer readings.
