Details about the GPS tracker: Model: A Tag/Y21 is compatible with Apple's Find My system. The device allows you to track the location of your four-legged friend through the Find My application. 📌 Main features: Model: A Tag/Y21 Battery: CR2025 (lasts 12 months🔋) Operating system: iOS 📍 Functions: Find your four-legged friend: If your four-legged friend is nearby, you can use the Find My application to see its exact location. Lost mode: If your four-legged friend is lost, you can activate the lost mode so that other users can find it and contact you. (You add a mobile number, so that whoever finds it can contact you). Or the application will automatically send a signal to its location if someone who uses Find my passes by. Sound signal: You can activate a sound signal from the Find My application to quickly find it. Questions you may have: 1. If the dog goes far away — for example, 900 meters, how can I find it? The “Find My” system helps you in just such cases — when you yourself are not near the tracker. This is possible thanks to Apple’s “Find My Network” technology: How Find My Network works: When your dog (with a GPS tag) is far from you, but another person with an iPhone or Apple device turns up on the road, their phone sends the location to your Find My app. That is, you will see the dog’s last location, even when you are not there. That is, you are not limited to a radius of only 100 meters — if your dog comes into the vicinity of Apple devices, you can find it through them. 2. Is the radius limited? If it goes 5 kilometers or more, will I find it? Yes, I will find it, the radius is not limited. It doesn’t matter if it is 1 km, 5 or 20 km away from you 3. If you lose your four-legged friend, do you need to have “Lost Mode” turned on? Not necessarily. You can see the tag’s location in the Find My app even when “Lost Mode” is not turned on. Lost Mode is just an additional feature that: allows you to indicate that your four-legged friend is lost. Shows contact information for other finders (you provide a contact number and they will contact you) sends you a notification when an iPhone finds the tag. That is, it is possible to find it via the Find My network even without Lost Mode. But with Lost Mode you have better control. 🔄 Connect to the Find My app: Remove the battery insulation sheet and press the button to turn on the device. In the Find My app, press the Items button, then + and select Add Other Item. The device should appear in the list; tap it and complete the connection.
