Fire, explosion, property damage, or bodily harm may occur if this warning is not followed. − Dispose of all packaging material properly. Some items may be packed in plastic bags. These bags could cause suffocation. Keep away from children and pets. − The battery should be charged in areas with temperatures ranging from 32°F to 113°F / 0°C to 45°C. Recharging the battery outside of this temperature range can cause the battery to overheat, explode or catch fire. − Check periodically to make sure the product has not been damaged or chewed by your dog or cat. Do not use if damaged. − Do not use the GPS Tracker with people, including children and those with limited physical, sensory or mental abilities. Use only with dogs or cats. − This is not a medical device and should not be used as a substitute for professional veterinary-medical judgment. It is not intended to provide medical or scientific data. − This system is not a physical barrier or containment solution. It is designed to notify pet owners when their pet exits a defined safe zone. It does not prevent pets from leaving the area, nor does it guide them back. All GPS Pet Trackers (cont.) • Do not rely solely on this system to monitor or protect your pet. Environmental factors, signal interference, battery life, and connectivity may affect system performance. Always supervise your pet and use additional safety measures as needed. • This product is not suitable for aggressive or unpredictable pets. If your pet poses a risk to others or may harm itself when outside the safe zone, consult a veterinarian or certified trainer before use. • The GPS Tracker is not a toy. Keep out of the reach of children. • Notification delays may occur. Cellular coverage, app settings, and device connectivity can impact the timeliness of alerts. PetSafe Brands cannot guarantee immediate notification in all circumstances. • Proper setup and regular maintenance are essential. Ensure the tracking device is securely attached, fully charged, and functioning properly. Periodically test the system to confirm safe zone boundaries and alert functionality. • The tracker is small in size and might be too large or heavy for small or injured dogs or cats. If you are unsure whether this product is appropriate for your dog or cat, please consult your veterinarian. • PetSafe Brands shall not be liable for any injury, property damage, or economic loss resulting from a pet leaving the safe zone. This includes, but is not limited to, incidents involving traffic, wildlife, or interactions with other animals or people. • GPS accuracy may vary. Location data may be affected by terrain, buildings, weather, or satellite availability. Safe zone boundaries should be set with a margin of error in mind. Location tracking is subject to limitations inherent in GPS and wireless technologies. These may include signal delays, reduced accuracy, or temporary loss of connectivity in certain areas. • This system is intended for use with domesticated pets only. It is not designed for livestock, wildlife, or animals with specialized containment needs. • This product relies on external systems such as GPS satellites and mobile networks. As with any technology, occasional disruptions may occur due to factors beyond PetSafe Brands’ control. • Use only charging devices that are approved by Radio Systems Corporation. Our accessories are designed for your device to maximize battery life. Using other accessories may cause damage to your device. • Do not allow electronics to contact liquids. • Extreme conditions, such as high temperatures or high humidity, can damage the device or impact the device’s performance. • You should expect hundreds of recharge cycles from your battery. However, do not charge your collar every night or leave it charging for extended periods once it is fully charged. • Overcharging can lead to overheating and reduce battery life. • Do not disassemble or modify the device in any way. Opening the device can lead to exposure to hazardous materials and may cause injury. Terms of U…
