Product Features:
1: the use of advanced digital audio signal processing (DSP) technology and FM modulation phase-locked           loop (PLL) to make sound more realistic, more stable performance, long working hours without frequency           offset.
2: LCD display is more intuitive and accurate, with very low power consumption and minimal noise interference.
3: with automatic station search and store radio features, easy to operate and use.
4: Built-in 30 digital volume adjustment, the key operation can be easily completed.
5: automatic power-down data memory before the power failure.
6: speaker / headphone output automatic switching
7: supports serial AT commands.
8: quartz crystal frequency stabilization, the temperature change is no longer transmitting frequency drift.
9: Auto search for full-band signal has a frequency band and store memories.
10: You can set the threshold processing DSP digital squelch, no signal automatically muted, away from the            traditional FM radio irritability rustle (requires the user to open the static noise function module).
