Maintenance and Care
- Cleaning: Wipe the ring with a soft, dry cloth to remove any dirt or smudges. Avoid harsh chemicals or abrasive materials.
- Durability: The micro-crystal Zr ceramic material is highly durable. However, avoid extreme impacts that could potentially damage the ring.
- Water Resistance: The ring has an IP68 protection grade, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for 30 minutes. It is suitable for daily use, including hand washing and showering, but prolonged submersion or use in high-pressure water is not recommended.
- No Charging Required: The ring operates on radio energy from read-write equipment, so no charging is ever needed.
Troubleshooting
- NFC Functionality with Smartphones: Most Android phones support NFC ring functions if their NFC feature is enabled. However, many iPhones may not support all NFC ring functions even if NFC is enabled, due to Apple's specific NFC implementation.
- Programming Limitations: The ring can be programmed with different functions, but only one program can be active at a time. Writing a new program will automatically overwrite any previously stored program.
- 125KHz T5577 Ring (ID Card): The T5577 125KHz chip in the ring is initially blank. It must be copied from an existing 125KHz card using a compatible copier. It cannot be directly authorized for use without prior copying.
- Programmed 125KHz Ring: Once a 125KHz ring has been programmed (copied from an existing card), it can only be authorized to work with compatible systems. It cannot be used to copy other cards.
- UID 13.56MHz Ring (IC Card): The UID 13.56MHz chip in the ring offers more flexibility. It can be used to copy existing IC cards or can be directly authorized to work with compatible systems.
- Reading Distance: Ensure the ring is within 1-3 cm of the reader for successful interaction.
