2. Setup
2.1 Line Winding and Learning Mode
Proper line winding is crucial for the accurate depth counter and optimal performance of your electric reel. The reel features a 'Learning Mode' to calibrate the line capacity and type. Always ensure the clutch lever is in the ON position before starting the winding process.
- Entering Learning Mode: Simultaneously press and hold the '0-SET' and 'MENU' buttons for 3 seconds or more.
- Selecting Line Type: Use the arrow buttons to navigate through the learning mode options (PE Line, Nylon/Fluoro, Underwinding). Select the appropriate option for your line type.
- Winding the Line: Use the technical lever to wind the line onto the spool. An alarm will sound, and the display will show numbers proportional to the spool's rotation. Maintain a tension of '3' during winding.
- Stopping Winding: To stop winding, set the technical lever to the 'OFF' position.
- Setting Line Length: Once winding is complete, press and hold the 'MENU' button for 3 seconds or more. An alarm will sound, and the display will show the line length setting screen. Use the arrow buttons or the lever to set the exact length of the line you wound (e.g., '200' for 200 meters).
- Confirming Setting: Press and hold the 'MENU' button for 3 seconds or more to confirm the setting. An alarm will sound, and the display will return to the water depth screen, indicating that the learning process is complete.
Note: The displayed counter value and the actual length of the line may have a maximum error of ±3%. If the count value is 6.1m or more, the reel will not enter learning mode.
2.2 Line Winding Correction
If you notice discrepancies in the depth counter after initial use, you can perform a line winding correction. This process adjusts the counter's water depth and line marker alignment for greater accuracy.
- Enter Correction Mode: Press and hold the 'MENU' button for 3 seconds or more to access the menu screen. Navigate to and select '糸巻学習補正' (Line Winding Learning Correction).
- Adjusting Depth: Adjust the displayed water depth to match the actual line position at the water surface. For example, if the actual depth is 30m, set the display to 30.0.
- Confirm Correction: Press the '決定' (Confirm) button to finalize the correction. An alarm will sound, and the display will return to the water depth screen, showing the corrected depth.
Note: This correction is effective when the counter value is 10m or more. If the display exceeds 100m, for example, changing from 199 to 200, adjust the display at that point for a more accurate correction. If the motor operates during correction, it will be canceled. The corrected value will be retained even if the power is turned OFF.
