Frequently Asked Questions

GN 9120

1. Is there any potential risk of hearing damage when using the headset?

GN Netcom products meet the highest user protection standards, with sophisticated sound limiting systems to protect the user against excessive sound levels. For that reason all GN headsets have incorporated protection circuits.

2. Has it been allergy tested?

Headband: The headband is made of stainless steel which does not have a nickel coated surface. The stainless steel alloy has been tested for nickel release in accordance with the European standard EN 1811:1998. The headband nickel release is well below the EN1811 limit.
Leatherette ear cushions: The leatherette ear cushion does not contain vinyl or latex.

3. How long is the warranty?

The GN9120 is covered by a two-year warranty. Quality issues that arise within this period will be solved at no charge to the customer, provided the product has been used for the purpose for which it was intended and has not been subjected to abuse.

4. How should I clean my GN9120?

The headset and the base unit should be cleaned in the same way as you would a handset, meaning that they can be cleaned with a cleaning tissue. Ear cushions can also be replaced.

5. What do I do if the headset is malfunctioning or damaged?

Please contact us with your problem and we will advise you on what course of action to take.

6. Apart from styles, what is the difference between boom arms?

The Micro-boom has a standard microphone.

The standard microphone is like the microphone in your telephone handset. This means that some of the background noise around you will be transmitted to the person your are calling. This type of microphone is commonly used in offices and in environments where the level of noise is limited.

The Flex-boom has a noise cancelling microphone and will dramatically limit the amount of background noise around you transmitted to your caller.

The Midi-boom has a noise filtering microphone which is not as effective as noise cancelling.

7. What if I still want to use my telephone handset?

Whenever the headset is placed in the base unit your telephone handset can be used. When the headset is removed from the base the link to the headset will be established.

8. Can I change the headset?

It is possible to connect a new GN9120 headset to the base. Just reset the system by removing the DC-plug for a moment. The system will then match the new headset to the base. For further information consult the user guide.

9. Can I use the headset on either ear?

Yes, it is easy to change the wearing style from right to left ear - please consult the user guide.

10. Can I answer and/or terminate calls when I’m away from my desk?

Yes - this feature requires a GN1000 hookswitch (available separately). Please consult your user guide for setup information.

11. Is it possible to change wearing styles?

It is very easy to change wearing style on the headset. You can choose between over-the-ear (earhook) and over-the-head (headband) wearing styles.

12. I am interested in the 9120 but have a WiFi network. Will it work?

GN Netcom have a large number of customers who are currently enjoying a GN 9120 within a WiFi environment. While both devices operate on the 2.4 GHz spectrum, The 2.4 GHz bandwidth is an extremely robust radio band. One of the key reasons for the broad acceptance of the 2.4 GHz band over the older 900 MHz band is its larger number of available channels - 95 versus 80. With 18% more bandwidth and Frequency Hopping Spread Spectrum (FHSS), multiple devices can operate without interference. In order to ensure optimal product performance we recommend not placing the 9120 immediately adjacent to an existing WiFi station and deploying multiple units incrementally. By deploying incrementally, a site can identify when it begins to approach its maximum capacity. A user will start to experience interference (clicks and pops), as an environment gets more crowded.

13. I have a 9120 and since I started using it, I am having problems with my WiFi network.

GN Netcom have a large number of customers who are currently enjoying a GN 9120 within a WiFi environment. However, wireless technologies are dependant on the environment in which they operate including structural issues (walls, fire doors, lift shafts, etc), electronic equipment (transformers, computer servers, poorly grounded fluorescent lights), and other wireless devices.

Suggested Tips:

• Re-establish WiFi station(s) and 9120(s), physically as far apart as possible. This should include all WiFi transmitters - including laptop cards and access points
  (or wireless routers).
• Consider shortening your 9120 roaming distance - just 5 to 10 feet could eliminate interference.
• If using multiple 9120s, temporarily decommission all 9120s and then incrementally (one-by-one) re-establish units to determine maximum saturation for your particular environment. A user will start to experience interference (clicks and pops), as an environment gets more crowded.
