Features:
1. The use of advanced digital audio signal processing technology (DSP) and FM phase-locked loop modulation technology (PLL) makes the sound quality more realistic, the performance more stable, the working frequency has no deviation for a long time, and the received signal is good.2.LCD display is more intuitive and accurate, with extremely low power consumption and minimal noise interference.3. It has the function of automatically searching for radio stations and storing radio stations, and is easy to operate.4. Built-in 30-level digital volume adjustment, which can be easily completed by pressing buttons.5. Automatically remember the data before the power outage.6. Using quartz crystal to stabilize the frequency, the emission frequency will no longer drift when the temperature changes.7. Full frequency band (76-108MHZ) automatically searches for signal frequency bands and stores memory.8. Built-in rechargeable lithium battery and charging circuit, you can charge it with a mobile phone charger, the red light will turn on when charging, and the green light will turn on when full;
