5.3 Important App Tips
- Single Device Connection: One BVM02 device can connect with only one smartphone at a time. To monitor with another smartphone, delete the device from the existing smartphone or disable Bluetooth on the current phone.
- Location Service Access: Please allow the app to access Location services, even if you are not actively using the app. This is a requirement for Bluetooth Low Energy (BLE) to function correctly on Android systems and ensures the Smart Sense will automatically notify you of any problems.
- Notification Access: Allow the app to access Notifications. Otherwise, you will not receive alert notifications. For Android users, ensure the app is allowed to run in the background.
6. Maintenance
- Keep Connections Clean: Periodically check the battery terminals and monitor connections for corrosion or dirt. Clean as necessary to ensure optimal contact.
- Secure Mounting: Ensure the monitor remains securely attached to its mounting surface. Reapply adhesive if it becomes loose.
- Software Updates: Regularly check for updates to the "Battery Sense" app through your device's app store to ensure you have the latest features and bug fixes.
- Environmental Protection: While the device has some water resistance (IP65, as per comparison image), avoid prolonged exposure to extreme moisture or direct water submersion.
