  • I have set up my Jabra GN9120/9125 correctly, but experience a buzzing sound on my headset.

    ​Your telephone may not be fully immune to the radio transmission between your headset and base. To remedy this issue try to move the base at least 30 cm / 12” away from the phone. If you have the European version, you can instead choose to set the headset to Low Power mode.

  • Does a Jabra GN9120 installation have any effect on WLAN installations?

    ​The Jabra GN9120 has three different versions: EU DECT, US DECT and a 2.4 GHz propriertery protocol variant. Both the EU DECT and US DECT variants co-exist well with WLAN. Since the products operate in different frequency spectrums, there is no interference at all.  The Jabra GN9120 2.4 GHz variant however operates on the same frequencies as most WLANs (WLANs usually operate on either 2.4 GHz or 5.8 GHz, only the 2.4 GHz networks are affected). If 4-5 pcs. Jabra GN9120 2.4 GHz units are placed close to the WLAN router this may significantly reduce the throughput of the WLAN. For increased performance, try to separate the WLAN router and the Jabra GN9120 2.4 GHz base units.

  • How does the Jabra GN9120 adjust its radio transmission power?

    ​The answer depends on the Jabra GN9120 model. The Jabra GN9120 GAP does not adjust radio transmission output power. All other Jabra GN9120 models adjust radio transmission output power depending on the transmission quality measured by the headset and base (bit error rate). At a given trigger level, radio transmission power is either turned up or down depending on if the signal quality between the base and headsetdecreases or increases.

    The distance between the headset and base and radio interference are both sources for altering the headset radio transmission output power.

    Maximum radio transmission output power is 63 mW. Even when the headset is docked in the base, the headset and the base are still transmitting. The transmission is however not as frequent as when the headset is taken out of the base docking station.

  • How good are the noise canceling effects between different types of the Jabra GN9120 variants?

    The Jabra GN9120 series contains 3 different headset models covering headsets with an omni directional microphone (normal microphone) (Jabra GN912x-48-xx), which have no noise canceling effect; headsets with a sound tube (Jabra GN912x-30-xx), which have little noise canceling effect; and headsets with a flex boom arm and a dedicated NC microphone (Jabra GN912x-28-xx), which have very good noise canceling effects.  

    The chart below presents an approximation of noise levels canceled by the different microphone types:

    • When I try to make a call using my desk phone, the Jabra GN1000 RHL lifts but the call is not connected.

      ​The Jabra GN1000 cannot be used in conjunction with a headset port. Make sure that the Jabra wireless headset base is connected to the desk phone handset port and not the headset port (if the desk phone has one).

    • Does a Jabra GN9120 installation have any effect on WLAN installations?

      ​The Jabra GN9120 has three different versions: EU DECT, US DECT and a 2.4 GHz propriertery protocol variant. Both the EU DECT and US DECT variants co-exist well with WLAN. Since the products operate in different frequency spectrums, there is no interference at all.  The Jabra GN9120 2.4 GHz variant however operates on the same frequencies as most WLANs (WLANs usually operate on either 2.4 GHz or 5.8 GHz, only the 2.4 GHz networks are affected). If 4-5 pcs. Jabra GN9120 2.4 GHz units are placed close to the WLAN router this may significantly reduce the throughput of the WLAN. For increased performance, try to separate the WLAN router and the Jabra GN9120 2.4 GHz base units.

    • How does the Jabra GN9120 adjust its radio transmission power?

      ​The answer depends on the Jabra GN9120 model. The Jabra GN9120 GAP does not adjust radio transmission output power. All other Jabra GN9120 models adjust radio transmission output power depending on the transmission quality measured by the headset and base (bit error rate). At a given trigger level, radio transmission power is either turned up or down depending on if the signal quality between the base and headsetdecreases or increases.

      The distance between the headset and base and radio interference are both sources for altering the headset radio transmission output power.

      Maximum radio transmission output power is 63 mW. Even when the headset is docked in the base, the headset and the base are still transmitting. The transmission is however not as frequent as when the headset is taken out of the base docking station.

    • How good are the noise canceling effects between different types of the Jabra GN9120 variants?

      The Jabra GN9120 series contains 3 different headset models covering headsets with an omni directional microphone (normal microphone) (Jabra GN912x-48-xx), which have no noise canceling effect; headsets with a sound tube (Jabra GN912x-30-xx), which have little noise canceling effect; and headsets with a flex boom arm and a dedicated NC microphone (Jabra GN912x-28-xx), which have very good noise canceling effects.  

      The chart below presents an approximation of noise levels canceled by the different microphone types:

    • What is the absolute maximum acoustical output of the Jabra GN9120?

      The ​Jabra GN9120 provides 10 different speaker volume settings (1-10). The volume range is 28 dB (from Level 1 to Level 10). The maximum acoustic output measured using a IEC318 coupler, with the speaker volume set to maximum (close field test method), is a sound pressure level of 115 dB SPL or 21 dB Pa.

      Using the UL test certification measurement setup - which involves a Head and Torso Simulator type 3.3 with artificial ear, standard pinna - and only using the headsets own force to press the speaker against the ear, a sound pressure level of 110 dB SPL (equivalent to 16 dB Pa) can be measured. The Jabra GN9120 has been tested and certified by UL/Demko using acoustic shock protection tests.

    • My GN9120 headset broke and had to be replaced, but my Jabra GN9120 base is in AEI hook mode. How can I pair the new headset with my existing base?

      Once the Jabra GN9120 base is in AEI mode, it is not possible to pair it with a new headset. If you have both the original base and headset, you can change the hook mode to DHSG or RHL, connect the new headset and pair it with base. Then you can switch the hook mode back to AEI.

      If your original headset is broken, you can contact Jabra Support for further assistance.
