Basic Instructions For Product Operation 深圳市创世达实业股份有限公司 Capacity: 240mAh@3V, 0.72Wh Frequency range of transmitter: 2.402 ~ 2.480 GHz Receiver frequency range: 2.402 ~ 2.480 GHz Transmission power: 3.36dBm Accepted power: -93dBm power dissipation: 30uA Connection distance: 20 meters Decibel: 80 decibels Waterproof level: IPX7 Brief introduction The AT01 positioning anti-lost device is a small Bluetooth locator that leverages the Apple Find My network. As long as there are nearby Apple devices (iPhone / iPad), it can establish connections via Bluetooth with these devices and upload the item's location information to Apple servers. Throughout this process, your privacy is always protected. Users can attach the AT01 to items such as keys, luggage, or handbags, and track their locations using the "Find My" application. If users cannot locate their items, they can mark them as lost, allowing other users of the "Find My" application to assist in locating the lost items. It features functions such as location tracking, lost item reminders, calling, privacy, and security. This product communicates with nearby Apple mobile devices using Bluetooth technology and shares its location with the Find My application. This allows you to see the last known location of the item on a map and get directions to its current location. An APPLE ID can connect up to 32 AT01 devices at most. Each AT01 can be customized with a name and emoji for easy management. ① Open the pre-installed Find My App on your Apple device. ④ Select "Other Supported Item" ② Choose "Items" ③ Select "Add Item" AT01 Instruction manual ⑤ Device Detection: During the "Searching Items" process, a device labeled AT01 will appear ⑥ Connect AT01 and name it ⑦ Using Device Features: A. Call Device: Click "Play Sound" to make the device emit a sound. B. Find My Network Assistance: When the device is out of Bluetooth range and cannot connect to the app, you can enable Lost Mode, enter a contact phone number, and if an iPhone is near the lost device, the owner's Find My app can receive a notification with the latest location. If your device or AT01 goes missing, you can put it in Lost Mode. That starts tracking its location, sends you a notification when it pings the network, and sets your passcode to protect your data. You can also let people know how to reach you. They can simply view your message on your device's Lock Screen, or tap your AT01 with their smartphone to get your contact info. Lost Mode： AT01 is designed to discourage unwanted tracking. If someone else's AT01 finds its way into your stuff, the network will notice it's traveling with you and send your iPhone an alert. If you still haven't found it after awhile, the AT01 will start playing a sound letting you know it's there. Of course, if you happen to be with a friend who has an AT01, or on a train with a whole bunch of people with AT01, don't worry. These alerts only get triggered when an AT01 is separated from its owner. Share This Item: After adding contacts in the Find My app, you can share the location of the product with family and friends. Remove Device: To remove the device from the app, select "Remove Item" Privacy： Install Battery: When installing the battery for the first time, the device will enter power-on mode.（The product comes with a pre-installed battery from the factory. There is a PC insulation sheet on the edge of the product. Pulling open this insulation sheet will automatically power on the product. If the battery inside the product runs out, you need to use a screwdriver to unscrew the screws, open the cover, and replace the battery. Ensure that the negative end of the battery faces downwards and the positive end faces upwards.) Power On: Insert the battery to power on the device. It will be in pairing mode for 10 minutes before timing out Confirm Device Status: Place the device logo side up for 5 seconds, then flip it upside down for 5 seconds. A sound will indicate it is working. Re-entering Pairing Mode After Timeout: ① If pairing is not completed within 10 minutes after the device powers up, reinstall the battery to enter pairing mode. ② After removing the device in the Find My app, the device remains in pairing mode for 10 minutes and emits a prompt tone. After timeout, reinstall the battery to enter pairing mode. Check Serial Number: Place the device with the logo facing up for 5 seconds, then flip it upside down for 5 seconds. Repeat this process twice. The device will emit six 'beep', entering serial number reading mode. Factory Reset: Reinsert the battery five times. The device will emit a sound, indicating the factory reset is complete. Enter Sleep Mode: Disable the Find My network and remove the battery, no indication. Note: TCP005 MaxConnection is 2. For TCB002, step 7, whether the accessory will respond with an invalid state error or not respond at all if the Firmware Update characteristic is written to while the accessory is connected to a non-owner? “ The accessory will respond with an ATT error (BT_ATT_ERR_WRITE_NOT_PERMITTED) if the non-owner writes to the Firmware Update characteristic. Essentially, it means that only the owner can perform the DFU.” Operation Instructions Post-Removal State: After removal, the device will not power off and will remain in p…
