Troubleshooting steps

1. ST5/ST6/ST9/ST10/SW2: Open the rubber charging-port cap and use the supplied adapter and cable. The red indicator stays on while charging and turns off when charging is complete. Disconnect the cable and close the cap.
2. SD1: Connect it to a 5 V / 1 A power source with a USB-C cable. Allow it to charge, then confirm that it powers on and appears normally in the Smart App.
3. MS1/MS2/MS3/LS1/LS2/LS3/LW1/LD1/SW3: Remove the battery cover and replace all AAA batteries with new batteries of the approved type. Do not mix old and new batteries or different brands. For LS1 in cold storage, use batteries rated for low temperatures.
4. ST8: Remove the battery cover and replace the 9 V 6LR61 battery.
5. Value still low: Put the Sensor next to its Hub. For models with a Setup button, short-press Setup for about 1 second; for SW3, single-press the data button. Then check the battery value in the MOCREO Smart App. If a replaceable-battery model still shows the old value, remove its batteries for 1-2 minutes, reinstall them, and check the App again.

Do not keep a rechargeable Sensor deeply discharged or charging after it is full. If the value stays low after the correct power action, provide the model, SN, battery state, deployment temperature, and Hub/App result to support.

To replace the LW1 batteries, carefully use a needle to lift the four white soft pads at the corners and expose the battery-cover screws. Remove the screws with a small screwdriver, open the Sensor battery cover, and replace the AAA batteries.
