Maintenance
Battery Life
The BFADEHA UCN3735 tracker is equipped with a long-lasting Lithium Manganese Dioxide cell, providing an estimated battery life of 5-10 years. The battery is non-replaceable and designed for extended use without maintenance.

- Check for obstructions that might muffle the sound (e.g., inside a thick wallet, under cushions).
- The alarm volume is up to 100dB, but environmental noise can affect audibility.
- Inaccurate location or delayed updates:
- Location accuracy depends on the density of the Apple Find My network. In areas with fewer Apple devices, updates may be less frequent or precise.
- Ensure your iPhone has a stable internet connection (Wi-Fi or cellular data).
