  • Audio settings can be programmed (volume settings, microphone sensitivity, PTT/PTM, HOOK events, etc)
  • All settings stored in hardware, configuration software: ChangeMe
  • Hardware Echo Cancellation
    For use with duplex audio, in case no echo cancellation is present in software, we offer an optional hardware echo canceler.
  • BeFREE 03
    In combination with the BF03, a compact and low-cost dispatching solution can be built.
  • Handset
    Because of the modular design, the BeFREE can be combined with one or more Handsets on the left or right side. The handset can be either:

    • USB; Besides the Handsfree audio, this offers an extra, independent, voice channel
    • Analog Switching; There is one audio (voice) channel that switches automatically from Handsfree to Handset when lifting the Handset.
  • Keyboard
    If more shortcut keys are needed, a programmable keyboard can be added to the BeFREE.
