Hytera BD555
Mobile radio for getting started in digital technology (DMR)
Product description
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.
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.
Features
- Analog & Digital Auto Detect
- Scan
