6. Maintenance
6.1. APE560 Call Button Battery Replacement
The APE560 call buttons are powered by an Alkaline 12V 23A battery with an estimated life of 12-18 months. To replace the battery:
- Locate the base key hole on the side of the call button.
- Use a small tool (e.g., a paperclip or small screwdriver) to gently open the waterproof base.
- Carefully remove the old battery.
- Insert a new Alkaline 12V 23A battery, ensuring correct polarity.
- Close the waterproof base securely.
6.2. Cleaning
- Wipe the receiver and call buttons with a soft, damp cloth.
- Do not use abrasive cleaners or solvents, as these may damage the surface.
- The APE560 call button has a 'general watering' waterproof rating, meaning it can withstand splashes but should not be submerged.
7. Troubleshooting
- No Signal from Call Button:
- Check if the call button's battery needs replacement.
- Ensure the call button is within the transmitting range (up to 800m in open space). Obstacles like thick walls can reduce range.
- Verify the call button is properly paired with the receiver.
- Receiver Not Displaying/Alerting:
- Ensure the receiver is properly plugged into a power source and turned on.
- Check if the volume or alert settings on the receiver are correctly configured.
- If multiple buttons are not working, there might be an issue with the receiver's signal reception or internal fault.
- Incorrect Number Displayed:
- This usually indicates a pairing issue. Re-pair the call button with the desired number.
