Help! My tCheck 2 device is stuck on all green lights.
All Green - Power On Self Test:
All green lights indicate that the device is in the Power On Self Test (POST) mode. Normally, this process takes about 10 seconds. If your device is stuck with 3 green lights for more than 15 seconds, please contact Customer Support.
Once the POST process is completed, the lights will turn blue-blue-green, meaning that the device is ready for a BLE connection to the app.
