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).
Mobile radio for getting started in digital technology (DMR)
The BD555 is a handheld radio with a single-line display for getting started in digital technology (DMR). It offers functions comparable to simple analog radios in the same price class, but with the advantages of digital transmission technology.
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).
Thanks to its innovative design, the BD555 offers better performance than analog radios. Its excellent reception properties ensure trouble-freevoice communication.
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.
Use of digital coding and correction technology makes it possible to transmit voices without any interference - even over large distances.
