What is the red blinking/flashing light next to the screen on DELTA Pro?
The little red light is the Bluetooth indicator and it will keep flashing when the Bluetooth is turned on.
Under normal circumstances, the Bluetooth is automatically turned on by default after powering on the DELTA Pro. If you want to turn off the Bluetooth function, you need to first turn off the Delta Pro, and then switch the standby switch to OFF, the Bluetooth indicator and function will turn off after 30 minutes.
If you need to turn on the Bluetooth function, just turn on the Delta Pro normally.
