Face-To-Face communication via NIB technology
NIB enables face-to-face communication within close range in
noisy environments.
The NIB technology enables wireless communication within a
10 m radius. Full duplex communication for up to four people
within this perimeter.

In noisy environments, simply walk close to the person you wish
to talk to. The NIB technology will softly fade in and out (5-10 m
radius) and allow communication with people who are close.
Stay within a 3-5 m radius for optimal communication signal.
When the four, full duplex transmitting channels are busy (1-4),
other users can still listen but are not able to transmit (5-9). The
upper limit of listeners is the number of people fitted into the
radius of 10 m rather than what the technology permits.
NOTE: When more than four users attempt to transmit via NIB,
the 5th user and beyond attempting to transmit will hear beeps,
indicating that the outgoing communication did not transmit.

Which NIB group you belong to depends on where you and the
other NIB headsets are located.
NIB operates when the environmental noise level exceeds
approx. 80 dB and when the noise is continous for approx.
1 second.
NIB also operates in less than 80 dB if the user presses the PTT
in either PTT mode or VOX mode.
Activating NIB (Fig 7)
Quickly double pressing the PTT will toggle between NIB PTT
ON/NIB OFF/NIB VOX ON.
Pressing and holding the NIB PTT button allows for
communications within the 10 m radius when in NIB VOX ON
mode and NIB PTT ON mode.
NIB VOX ON - In this mode, high levels of noise will activate
the NIB radio and allow VOX communications for up to four
users. Pressing the PTT button in VOX ON mode also allows for
communication in quiet.
When the headset operates in an environment with intermittent
noise, noise can activate NIB VOX repeatedly. In this situation,
you can use NIB PTT ON.
NIB PTT ON - In this mode, the PTT button must be pressed to
transmit.
NIB OFF - This mode TURNS OFF the NIB radio. In NIB OFF,
no RF signal is being emitted from the NIB radio.
Push-To-Talk for NIB (Fig 8)
Press and hold the PTT button on the left cup to transmit on the
NIB radio.
Entering the Menu (Fig 4)
1. Press and hold the [+] and [-] buttons to enter the menu. A

3. Use the [+] button to change the setting and, if applicable,
toggle through the available settings. A voice message confirms
each step, followed by the current setting. Changes are also
confirmed by a voice message. After a few seconds of no
activity, the menu returns to volume mode. By pressing [+] and
[-], the volume setting can be instantly reached at any stage of
the menu.
