If you are having trouble connecting your N70 device to the app, there are a few things you can try to troubleshoot the issue.

Firstly, check whether the Bluetooth function of your mobile phone is normal. Make sure that Bluetooth is turned on and that your phone is visible to other devices. If you are unsure how to do this, check your phone's user manual or search online for instructions specific to your device.

If the Bluetooth function is working properly, try restarting your mobile phone and resetting the dashboard by disconnecting and reconnecting the instrument harness. This can often resolve connectivity issues.

If you have tried these steps and are still unable to connect to the app, it may be necessary to replace the dashboard or instrument harness. This can be done by contacting customer support for further assistance.

Remember, it is important to keep your N70 device and app updated to ensure optimal performance. Check for updates regularly and follow any instructions provided by the manufacturer to keep your device running smoothly.
