This document describes the Neostar CD Radio Cassette, product code 3244363, an electronics device designed for audio playback and recording.
Function Description:
The Neostar CD Radio Cassette is a versatile audio system capable of playing CDs, MP3 files from USB storage media, and cassette tapes. It also features an FM radio tuner.

Important Cautions:
- Usage of controls or adjustments or performance of procedures other than specified may result in hazardous radiation exposure.
- This unit should not be adjusted or repaired by anyone except qualified service personnel.
- Since movement of the CD mechanism and sensitive circuitry may cause interference to the radio tuner, switch off while operating other radio devices.
- In the unlikely event the unit 'hangs', unplug from the main power supply to restart.
- Connecting the USB upside down or backwards could damage the audio system or storage media.
- The system can only detect and read MP3 files in USB mode; other music file formats are not supported.
- Due to variances in MP3 encoding format, some MP3 players may not be able to play via the USB socket. This is not a malfunction.
- USB port does not support connection with USB extension cable and is not designed for communication with a computer directly.
- The system has no delete function for MP3 files; manage erasing files via computer or other device.
