2. Setup
2.1. Battery Installation
The Fishing Electronic Indicator requires three AG13/LR44 button batteries for operation. To install or replace batteries:
- Locate the battery compartment, typically on the underside or side of the device.
- Open the compartment cover.
- Insert three AG13/LR44 button batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.

2.2. Attaching to Fishing Rod
The indicator features a clip-on design for easy attachment to your fishing rod:
- Open the clip mechanism of the alarm.
- Securely clip the alarm onto your fishing rod. Ensure it is firmly attached to prevent it from falling off during use. The design is intended not to damage your fishing rod or line.
- Wrap your fishing line around the alarm's sensor mechanism.
- Press the power switch button located on the front of the device to turn it on.


3. Operating Instructions
Once the device is properly installed and powered on, it will monitor your fishing line for activity. When a fish bites and pulls on the line, the indicator will activate a dual alarm system:
- Loud Sound Bell: A distinct audible alarm will sound, detectable even from a distance of 50 meters.
- LED Indicator: A bright LED light will flash, providing a visual alert, especially useful during night fishing or in low-light conditions.
The device incorporates patented buffer technology to enhance sensitivity while minimizing false alarms caused by water flow or wind noise.



4. Maintenance
4.1. Cleaning
To ensure optimal performance and longevity of your fishing indicator:
- Wipe the device with a soft, damp cloth after each use to remove any dirt, salt water, or debris.
- Do not use abrasive cleaners or solvents, as these may damage the ABS material or electronic components.
- Ensure the device is completely dry before storage.
4.2. Battery Replacement
When the alarm sound becomes faint or the LED indicator dims, it's time to replace the batteries. Follow the steps in Section 2.1 for battery installation. Always use three new AG13/LR44 button batteries.
4.3. Storage
Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the batteries to prevent leakage.
5. Troubleshooting
If you encounter issues with your Fishing Electronic Indicator, try the following:
- No alarm sound/light:
- Check if the device is powered on using the front switch.
- Ensure batteries are correctly installed with proper polarity.
- Replace batteries with new AG13/LR44 button batteries.
- False alarms:
- Ensure the fishing line is properly wrapped around the sensor and not too loose or too tight.
- Check for excessive wind or strong water currents that might be causing false triggers. The device's buffer technology minimizes this, but extreme conditions can still affect it.
- Re-position the alarm on the rod to a more stable location if possible.
- Alarm too quiet/dim:
- Replace batteries with new ones.
- Ensure there are no obstructions covering the speaker or LED light.
