1. Check whether the battery is loose. Install the battery properly to stabilize the battery.
2. Check whether the code scanning and NFC reading are performed when the battery is low. You are advised to stop these power-intensive functions immediately after the power alarm is generated. Otherwise, unnecessary losses may be caused due to terminal shutdown.
3. Is the terminal affected by a large collision? The impact may shut down the system for self-protection or cause abnormal battery differential power-off. Please handle electronic products, especially batteries, with care.
