Battery, standby, and environment check
Potential Causes
- Battery level is too low.
- The device has been in standby mode for more than 3 minutes.
- The device has stayed in the zone-switching state for too long.
- The device has been stored or used in a low-temperature environment.
Troubleshooting Steps
- Check the battery level
If the battery level is below 10%, the device may shut down automatically. Please fully charge it before use. - Check standby time
If the device is left in standby mode for about 3 minutes without operation, it will automatically power off. This is normal. - Check zone-switching time
In STAMP mode, if the device stays in the zone-switching state for too long without operation, it may also shut down automatically. Simply turn it on again. - Check the environment temperature
The recommended operating and storage temperature is 5–35°C.
If the device has been left in a cold environment, place it in a 5–35°C environment for a while before use.
