- **Battery Display:** Shows current battery level.
- **Timing Icon:** Indicates scheduled feeding times are active.
- **Feeding Icon:** Indicates a feeding cycle is in progress or recently completed.
- **Display of Feeding Interval Days:** Shows the frequency of feeding (e.g., every day, every other day).
- **Amount of Feed to be Fed:** Displays the set portion size.
- **Current Time:** Shows the current time for scheduling.
6.2 Setting Feeding Schedules
The feeder allows for precise control over feeding times and quantities:
- **Feeding Frequency:** The B-series models can be set to feed up to 6 times a day. You can also set it to feed every other day.
- **Portion Size:** Adjust the amount of feed dispensed per feeding, from 0 to 9 servings. The feeder uses an ultra-precision spiral grain discharge structure for accurate control.
- Refer to the specific buttons on the feeder (usually indicated by icons like a clock for timing, gears for settings, etc.) to navigate the menu and set your desired schedule.

6.3 Manual Feeding
A manual feeding option is available for immediate dispensing of food outside of scheduled times. Consult the feeder's buttons for the manual feed function (often indicated by a fish icon or similar).
6.4 Feed Mechanism
The feeder incorporates a newly optimized and upgraded export system with a spiral grain discharge structure. This design ensures precise control of feed volume and prevents jamming, allowing for smooth and consistent dispensing of various feed types.

7.2 General Care
- Wipe the exterior of the feeder with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Regularly check the feed bin for any signs of moisture or mold, especially if using different types of food.
- Ensure the sealing top cover and grain outlet are free from debris to maintain moisture protection.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Feeder not dispensing food | Low battery, feed bin empty, feed jammed, incorrect settings. | Check battery level and replace if necessary. Refill feed bin. Check for blockages in the spiral mechanism and clear if found. Verify feeding schedule and portion settings. |
| Food getting wet/moldy | Sealing cover not properly closed, high humidity, damaged seal. | Ensure the sealing top cover is closed tightly. Check the grain outlet for proper closure. Store the feeder in a less humid environment if possible. Inspect seals for damage. |
| LCD display not working | Low or dead batteries. | Replace all 3 AA batteries with new ones. |
9. User Tips
- **Small Portions:** The feeder is capable of dispensing very small amounts, such as 2-3 pellets per serving, making it suitable for single fish like Bettas.
- **Battery Life:** With 3 AA batteries, the feeder can operate for approximately 4 months, reducing the frequency of battery changes.
- **Flexible Scheduling:** You can program the feeder to dispense food not just daily, but also every other day, providing flexibility for different fish species' needs or vacation schedules.
- **Quiet Operation:** The feeder operates at a low noise level (20-30dB), ensuring it won't disturb your household or your fish.
