8. Troubleshooting
| Problem | How to proceed |
| 01: The device shut off working for a while. | (1) Check if the device has automatically shut off due to the timer function (default 30 minutes). (2) Recharge the device. Low battery levels can affect performance. |
| 02: The device shut off working for a while and restarts on its own. | (1) The current voltage may be too low. Recharge with a 5V 2A adapter. (2) When BLE is connected, the timer settings are needed, please use the app. |
| 03: Cannot connect to BLE. | (1) First, ensure the device is turned on. (2) Follow the app's instructions to connect. (3) Try deleting the device from your phone's Bluetooth settings and re-pairing. (4) For Android systems, go to Settings > Permissions > App info > Comfytemp > Permissions and ensure all necessary permissions are granted. (5) To find the problem, check if the product's battery life will be affected by the temperature settings. |
| 04: The product temperature is too high and has caused redness. | (1) It's recommended to use over thin clothing and start at the lowest temperature setting for 20 minutes. (2) For safety, the highest temperature is limited. If the redness disappears quickly, it may be caused by the local stimulated, increased blood circulation. (3) Please lay the product flat to cool down before using it again. |
| 05: The device display F1. | This indicates a fault. Please contact customer support. |

Try using a different 5V 2A adapter or charging cable. If it kept plugged in, it may go back to charging again, causing the UID to switch from "solid green" (fully charged) to "flashing green" (charging), which might lead to shorter battery life. Note: To extend battery life through regular charging, it is recommended not to leave the device plugged in for extended periods after it is fully charged. |
