Handy Talky Hytera BD555 Dual System Mode (System Analag & System Digital)
Hytera 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
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.
