    Display

    With a single-line display for the indication of the channel identifier (channel alias), name of the caller (caller alias) and the ID on pressing thepush-to-talk button (PTT ID).

    Excellent performance

    Thanks to its innovative design, the BD555 offers better performance than analog radios. Its excellent reception properties ensure trouble-freevoice communication.

    Robust and durable

    The BD555 was developed and tested in compliance with the military standard MIL-810 G. The dust and water-proof construction as per IP54 ensures reliability in different environments.

    Clear voice

    Use of digital coding and correction technology makes it possible to transmit voices without any interference - even over large distances.
