A1 The frequency range has changed to the 1.9GHz radio band
– called DECT 6.0. DECT 6.0 has the following advantages:
Interference free frequency band:
The 1.9GHz radio band is reserved for DECT 6.0 communi-
cations providing low interference and high quality audio.
Coexisting with other radio frequencies:
DECT 6.0 wireless headsets won’t interfere with, or receive
interference from, WiFi networks, wireless security sys-
tems, cellular phones, or any other wireless equipment.
Commercial-grade digital encryption and interference-
avoidance frequency hopping ensure privacy and security
– so no one can eavesdrop on wireless conversations.
Q2 What is DECT?
A2 DECT stands for Digital Enhanced Cordless Telecommunica-
tion and is a common standard for wireless telephony,
messaging and data transmission. It is a radio technology
suited for voice, data and networking applications in
residential, corporate and public environments, with range
requirements up to a few hundred meters.
Q3 Will the physical appearance of the GN9125 be the

A4 Yes, both the set-up of the units and day-to-day use have
been very well received in the market and no changes have
Q5 I have a WiFi network. Can WiFi and the GN9125 coex-
ist in the same location?
A5 Yes they can, and there will not be any interference. The
GN9125 series operate in different frequency bands than
WiFi equipment/Wireless LANs.
In North America, the GN9125 series utilize the newly
opened DECT 6.0 frequency band (1920-1930 MHz), while
other countries utilize the DECT band at 1880–1900 MHz.
These DECT bands are not used for WiFi equipment, Wire-
less LANs etc., as they typically operate in the 2.4 GHz or 5
GHz frequency bands.
Q6 Is it possible to listen in to conversations made with
GN9125 wireless headsets?
A6 The risk of unauthorized access to DECT voice calls is
extremely limited. Just like GN Netcom’s other wireless
headsets, the GN9125 digitally encrypt any call, providing
complete calling security and conﬁdence.
Q7 There is no sound in my headset (speaker)?
A7 Check that all units, cords and jacks are connected as
shown in the user guide. Make sure that the base unit has
power on. Check that the on-line indicators are lit up. Make
sure the unit is fully charged. Otherwise, please contact
your local distributor or reseller for further information
Q8 The person on the other end can’t hear me at all?
A8 Check that the units are correctly connected. Make sure
that the mute function is off and that the battery is fully
charged. Alternatively, you may be out of range, and you
should move closer to the base unit.
Q9 The person on the other end can barely hear me?
A9 Re-adjust the microphone volume as explained in the user
manual and make sure that the telephone termination
switch is in the correct position. Check the position of the
headset microphone and make sure that it is placed at the
corner of your mouth.
Q10 My headset/handset is buzzing/howling?
The base unit may be too close to your phone. Move the
base unit away from your telephone. If this doesn’t help,
please contact your local distributor or reseller for further
information and assistance.
Either your microphone volume control is too high for your
phone, or your phone’s volume control is too high. Try
adjusting one or both controls down to a suitable level.
Q11 I can hear my own voice in my speaker?
A11 This is normal. It’s called ”the sidetone signal.” If you think
the sidetone signal is too loud, ﬁne-tune your signal by
adjusting the microphone volume to a lower setting as ex-
plained in the user manual. Turn down the volume on your
telephone if it is equipped with a volume control.
Q12 What if I want to use my handset?
A12 You can still use your handset when the GN9125 is con-
nected. When the headset is removed from the base the
headset is the active part and when the headset is placed
in the base the handset can be used as normally.
Q13 Can I answer and/or terminate calls when I’m away
from my desk?
A13 If the hook-switch functionality is supported on your
telephone, it is possible to answer calls remotely. Please
consult the user guide.
Q14 What is the range on the GN9125 headsets?
A14 The range between the headset and the base is up to 300 ft.
