Warning: The unique cover design is intended to prevent children from easily opening the device. Keep batteries out of reach of children. Swallowing a coin cell battery can be dangerous.
6.2 Water Resistance
The Air Tracker S2 has an IP67 rating, meaning it is resistant to dust and can withstand immersion in water up to 1 meter (3.3 feet) for up to 30 minutes. It is not recommended for prolonged submersion or use during water sports.
7. Troubleshooting
- Tracker not connecting: Ensure Bluetooth is on, your iOS device is running iOS 14.6 or later, and the tracker's battery is not depleted. Try resetting the tracker by removing and reinserting the battery, then attempt pairing again.
- Sound is too quiet: The tracker emits a 90dB sound. Ensure there are no obstructions muffling the sound. If the sound is consistently low, the battery may be weak.
- Inaccurate location: Location accuracy depends on the density of the Apple Find My network in the area. In remote locations, updates may be less frequent.
- Battery drains quickly: Ensure the tracker is not constantly out of range, which can cause it to search for a connection more frequently. Replace the battery if it's nearing the end of its life cycle.
