  • Antenna

    Enhance signal receiving ability.

  • Channel knob

    Supports 16 channels to be changed very easily.


    With digital encoding and correction technology, human voice is transmitted much clearer without background noise, even from great distances.This is the next generation audio quality experience.

  • LED indicator

    Show the radio receiving and transmitting status as green light and red light.


    Based on TDMA technology, BD502i in digital mode can work as long as 16 hours @ 1500mAh or 22 hours @2000mAh in 5-5-90 mode.


    BD502i/BD552i is designed and tested to meet Military Standards 810 C, D, E, F and G, including temperature shock, vibration, high & low temperature and humidity. IP54 dust- and water-proof design guarantees the reliability in different environments. And based on TDMA technology, the radio can work longer, up to 22 hours in digital mode.

  • Speaker and Microphone

    Provide clear receive and transmit audio.
