Frequently Asked Questions
Frequently Asked Questions

FAQ - Top 5 questions

  • What to do if I have a hard time hearing the person on the other end of the line when I use my Jabra BIZ 2400?

    ​If you have difficulty in hearing the person on the other end of the line then try turning up the volume on the phone or amplifier. If the problem persists, you should consider switching from a mono to a duo headset. 

    In such situations, use of an amplifier such as the Jabra GN8210 is also recommended. This makes it possible to turn up the volume. Use of DSP (Digital Signal Processing) also helps adjust sound levels to match user preferences and requirements.

  • How does the Jabra BIZ 2400 eliminate unwanted noise?

    The Jabra BIZ 2400 features Jabra's PureVoice Noise Canceling system (NC) that blocks out unwanted background noise with greater precision than ever before and carefully distinguishes between your voice and any interference from other sound sources.

    There is also an option for an Ultra Noise Canceling (UNC) microphone for use in environments with very high levels of undesirable noise, and in which it is still necessary to maintain high levels of voice clarity in the phone conversation.

  • Is Jabra BIZ 2400 Series safe to use?

    ​The Jabra BIZ 2400 Series features GN Netcom PeakStop technology, which protects users against the effects of any sudden spikes of loud sound. For example, the highpitch tone from a fax machine can be harmful to a headset user’s hearing. Many acoustic experts define acoustic shock as being exposed to a sound in excess of 135 dB SPL. In fact, lower sound levels can also damage the ears.

    The Jabra BIZ 2400 Series therefore — like all other Jabra headsets — cuts off sounds at 118 dB SPL (RMS). The Jabra BIZ 2400 USB incorporates Jabra SafeTone technology to ensure safe average sound levels, making it the world’s first corded USB headset with built-in compliance to the strict noise-at-work regulations in force in EU countries.

    Used with the Jabra GN8210 digital amplifier, Jabra BIZ 2400 IP and Jabra BIZ 2400 headsets also comply with international health and safety directives to protect users against dangers associated with long-term cumulative noise exposure.
