Bluetooth matching

• Place the product near a Bluetooth mobile phone at a distance within 10 meters of the effective distance.

• Make sure that the product is turned on

• Turn the signal selection switch to Bluetooth, and then the signal light 2 lights up in blue flashing. The music knob lights up in blue backlight, while the Bluetooth is waiting for connection. And then, turn on the Bluetooth switch in the devices with Bluetooth function, such as mobile phone IPAD, etc. Select “LP-S5 I T” among the search results and click on the device name to complete the connection pairing. At the moment, the voice prompts “Drop”. After it is paired successfully, the signal light 2 becomes the aircraft light and slow flashing when playing. After pausing, it becomes the aircraft light.
  aircraft light(It is in a cycle of flashing twice a second and pausing for two seconds). (If the connection is not successful, please check a and b items)

  • a. Check if the Bluetooth of the mobile phone is successfully connected to the wireless device
  • b. Check if Bluetooth is connected to other phone

• When the mobile phone (IPAD) is paired with the amplifier, the blue light of the signal light 2 becomes flashing quickly, while other Bluetooth devices can search for this device. It becomes the aircraft light after connecting successfully.

• When restarting the paired mobile phone or the product at the same time, the product will automatically enter the connection function state and automatically connect to the Bluetooth device that was connected last time.

• When the phone exceeds the rang of 10 meters of the product, the blue light will turn to fast flashing for 30S. If it is not connected after 30S, it will light up for a long time and will automatically connect after returning to the effective distance.
