Your 9350 base unit has a LCD display and display control (please note that the 9330 does not have the LCD screen) with which you control 5 settings:
1 Transmit volume setting
2 Hookswitch selection (EHS in Europe Only, currently not approved in U.S.)
3 Range/power selection
4 Sound mode selection
5 Protection level selection (IntelliTone®)
Navigation and markers
Navigate through the LCD display’s 5 menus horizontally using the display control’s arrows. Within each of the 5 menus, navigate vertically with the display control’s arrows.
Press the OK button to confirm a specific choice/value within the 5 different menus. A star (*) beside a selected choice/value indicates the current setting.
The LCD display is always on and ready to use. The permanent default/start position for the LCD display is the leftmost transmit volume setting . The LCD display will always revert to this default/start position, if not operated for 30 seconds.
Within each of the 5 menus, there is also a factory-set default. This default remains until you change it. The last selected choice/value (within each of the 5 menus) is always displayed in the first line of its menu.
Changing the settings
Transmit volume (microphone)
The transmit volume must be adjusted properly so your voice is heard clearly. If you haven’t already adjusted the transmit volume during your initial setting up, do so now by completing the following:
1. Put on headset.
2. Use the arrows to locate transmit volume menu on base display.
3. Make a call to someone who will act as a test person.
4. Use the arrows to scroll through 12-setting transmit volume menu until your test person confirms your voice is at the appropriate volume.
5. Press OK to confirm new setting.
The transmit volume menu is the permanent default/start position for the LCD display. After adjusting any of the other settings via the display, it will revert to the transmit volume menu position.
Important: For USB applications, the volume settings are fixed and need no adjustment.
Hookswitch selection (EHS in Europe Only, currently not approved in U.S.)
The GN 9350 enables you to answer and end calls remotely by using the GN 1000 RHL, or its built-in electronic hookswitch (EHS) modes. EHS is only possible on certain telephone systems.
In order to determine which telephones have the EHS feature enabled, please refer to the GN website www.gnnetcom.com/gn9120/ehs-setup. Please also refer to your telephone´s user manual for clarification. 4 modes are available:
1 GN RHL non-EHS; works with the GN 1000 RHL
2 DHSG e.g. Siemens and Elmeg desk telephones
3 AEI e.g. with Tenovis desk telephones
4 MSH e.g. with Alcatel desk telephones
Note: By default, the GN 9350 is set to the RHL interface, which also is the correct setting if you manually operate your handset when answering / ending calls as described in the Guide for basic set-up and use.
To select the appropriate interface:
1. Use the arrow keys to locate the hookswitch selection menu
on base display.
2. Use the arrow keys to select one of the 4 interfaces from the menu.
3. Press OK to confirm the interface.
Note: To use the DHSG, AEI or MSH function, connect the connection
cord (accessory) to your desk telephone and the AUX port of
the GN 9350.
Your headset offers 3 range/power modes (Normal, Low and Very Low). The Normal mode is ideal for most users. However, if you experience interference from other communication devices during your calls, you may want to switch to the Low or Very Low modes. Changing to Low or Very Low power modes will reduce the range of your headset.
Power mode DECT Range US DECT
Normal Up to 100 m Up to 300 ft
Low Up to 50 m Up to 150 ft
Very Low Up to 20 m Up to 60 ft
* In typical office environment
Note: The Normal power mode is the default setting.
To change the range/power mode:
1. Use the arrow keys to locate the range/power mode menu on base display.
2. Use the arrow keys to select one of the 3 modes from the menu.
3. Press OK to confirm the new mode.
Sound mode selection
This menu is split into two sections: “Treble/Normal/Bass” and “Fixed/Switch”. These two sections are separated by a blank line. It is possible to choose one mode in each of the two sections.
Your headset offers 3 treble/bass modes (Treble, Normal and Bass). You can change these to suit your personal preferences or needs, and separately determine the USB sound quality.
Sound mode Effect Benefits:
Treble Accentuates high tones Ideal for users with slight high-frequency hearing loss
Normal Accentuates all tones evenly Ideal for all users
Bass Accentuates lower tones Ideal for users preferring a bass-rich sound
Note: The Normal mode is the default setting.
Sound mode Effect Benefits:
Fixed Speech quality in headset loudspeaker as known from traditional telephones (narrowband)

2. Use the arrow keys to select one of the 3 modes from the menu, and choose between fixed/switched from the menu.
3. Press OK to confirm the setting.
Protection level selection
Your headset offers a choice of 4 protection levels (plus its additional basic protection level). These levels protect you against sudden, overly loud sound spikes that may come from the phone network (such as shrill telefax signals or network interference), and provide a limit to the maximum noise exposure from the headset during your workday.
The number of hours (on average) you spend on the telephone per day determines the setting you should select. All 4 protection levels meet and exceed de facto global protection levels, and are compliant with NIOSH standards, and EU health and safety codes of 85 dB(A). The TT4 protection level is compliant with pertinent Australian recommendation. Important: In some jurisdictions, applicable regulations or laws may mandate the required setting you use. The Default level provides a protection level of 118 dB(A). Your headset protects you against overly loud sound spikes. If you use the telephone’s handset for calling, you will not have this protection.
Protection level Criteria for selecting
Level 0 Basic protection against overly-loud sound spikes
[118 db(A)]. Auto volume disabled
Level 1* Less than 4 hours on telephone/day
Level 2* 4-8 hours on telephone/day
Level 3* More than 8 hours on telephone/day
Level 4 (TT4) Recommended Australian protection level (Telstra)
* Compliant with Directive 2003/10/EC of the European Parliament and Council of 6 February 2003.
To change the protection level:
1. Use 34 to locate the protection level menu on base display.
2. Use 56 to select one of the 5 modes from the menu.
3. Press OK to confi rm the new mode.
Automatic volume adjustment and noise reduction
Your headset offers two built-in features which give you optimum sound levels and quality. Both features operate automatically, so you need not make any adjustments to the headset.
Automatic volume adjustment
The automatic volume adjustment feature automatically sets the volume levels of all calls, so that each call is heard at the same, consistent volume you have set. Autovolume is not enabled in protection level 0.
The automatic noise reduction feature improves the sound quality of incoming calls by removing impurities transmitted with the signal, such as background noise from your caller’s environment.
