A new connection is only possible if the Power LED is off (it indicates that no device is connected). If
a problem with Bluetooth connection occurs, it is necessary to reset memory and to delete all paired
devices. For reset turn off the unit > disconnect power supply > press & hold power button >
connect power supply > still hold power button for another 5 seconds > release power button. The
blue LED above the power button will blink for few seconds. When the LED stops blinking, memory is
erased and you can turn on the unit.
