6.2 Battery Care
- To maximize battery life, avoid fully discharging the battery frequently.
- Charge the device using only the provided charger or a compatible charging base.
- Avoid exposing the device to extreme temperatures, as this can degrade battery performance.
- If the device will not be used for an extended period, charge it to about 50% before storing.

6.3 Software Updates
Periodically check for and install software updates to ensure your device has the latest features, security patches, and performance improvements. Updates can typically be found in the device's 'Settings' menu under 'System' or 'About phone'.
7. Troubleshooting
7.1 Device Not Powering On
- Ensure the battery is sufficiently charged. Connect the device to a charger and wait a few minutes before attempting to power it on again.
- Press and hold the Power button for at least 10-15 seconds to perform a forced restart.
7.2 Barcode Scanning Issues
- Ensure the scanning application is open and active.
- Check that the barcode is clean, undamaged, and well-lit.
- Adjust the distance and angle between the scan head and the barcode.
- Verify that the scan head is not obstructed or dirty.
- Restart the scanning application or the device.
7.3 Connectivity Problems (Wi-Fi/4G)
- Wi-Fi: Check if Wi-Fi is enabled in settings and if you are connected to the correct network. Try forgetting the network and reconnecting.

8. User Tips
Based on general usage and product features, here are some tips for optimizing your experience with the Sunmi L2:
- Optimize Battery Life: For extended use, especially during long shifts, consider carrying a portable power bank or utilizing the charging base during breaks. The 5000mAh battery is designed for durability, but heavy usage of 4G and scanning can deplete it faster.
- App Management: Regularly close unused applications running in the background to free up RAM and improve overall device performance.
- Screen Protection: While the device is rugged, applying a screen protector can further safeguard the 5-inch HD IPS display from scratches in demanding work environments.
- Data Backup: Periodically back up important data to a cloud service or external storage to prevent loss in case of unforeseen issues.
- Leverage PSAM Card: If your operations involve specialized security or identification needs (e.g., law enforcement, public transport), ensure you utilize the optional PSAM card slot for enhanced functionality and security.
