LP10 Principle description
1、 The power supply is input to DC15V 2.4A from the external adapter to
the host input socket。
2、 Power Switch: Turn the switch to "ON" to power on, and to
"OFF" to power off.
3、 Button Panel: Includes Mode button, Play/Pause
button, 33.33 RPM button, and 45 RPM button.
①Press the MODE button once to switch between Bluetooth mode and LP
mode. Red indicator light means LP mode, blue indicator light means Bluetooth
mode.
②Press the Play/Pause button once in LP mode to play music; press again to
pause playback.
③ Press the 33 button once to set the turntable speed to 33.33 RPM.
④Press the 45 button once to set the turntable speed to 45 RPM.
4、 Volume Potentiometer Knob: Adjust to increase or decrease the volume.
5、 PHONO/LINE OUT Switch:When switched to PHONO, the AUX OUT
outputs the analog audio signal from the vinyl record,When switched to LINE OUT, the AUX
OUT outputs the audio signal after pre-amplification processing.
6、 USB Port: Digital audio signal output interface.
7、 AUX OUT: Audio signal output interface for connecting to external
powered audio equipment.
8、 Ground Screw Post: For connecting to the chassis ground.
9、The RFprovides the standard oscillation frequencyto the Bluetooth chipthrough the
24 MHZ crystal vibration. After the internal signalprocessingof the Bluetooth chip, the
antenna sends the2.4 GHz Bluetooth carrier signal to the main device through the
tuningcircuit, and the antenna receives the data flow and control signal of the main device
through the antenna, and sends it to the relevant components to realize the Bluetooth
audioplayback and control.

Federal Communications Commission (FCC) Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However,there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
●Reorient or relocate the receiving antenna.
●Increase the separation between the equipment and receiver.
●Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
●Consult the dealer or an experienced radio/TV technician for help.
Warning: Changes or modifications made to this device not expressly approved by
may void the FCC authorization to operate this device.
Note: The manufacturer is not responsible for any radio or TV interference caused by unauthorized
modifications to this equipment. Such modifications could void the user’s authority to operate the
equipment.
RF exposure statement:
The transmitter must not be colocated or operated in conjunction with any other antenna or
transmitter. This equipment complies with the FCC RF radiation exposure limits set forth for
an uncontrolled environment. This equipment should be installed and operated with a Minimum
distance of 20cm between the radiator and any part of your body.
