Jabra PRO 9460, Jabra PRO 9460 DUO, Jabra PRO 9465 DUO AND Jabra PRO 9470 USER MANUAL
How to replace the battery on Jabra PRO 9460 Duo and Jabra PRO 9465 Duo
7.5 STAYING WITHIN RANGE
Jabra PRO supports a maximum range of up to 150m. In practice, you will probably find the range to be somewhat
shorter due to physical obstructions and electromagnetic interference.
If you move the headset totally out of range of the base so that the DECT signal is lost, a unique tone is played in
the headset every few seconds — see the section “Headset Signal Tones” for more.
The sound in your headset will slowly deteriorate as you move farther from the base; move back into range to
restore sound quality. If you move all the way out of range while talking, you lose the conversation audio but
your call will be held open at the base for 60 seconds, giving you a chance to move back in range; after this time
the current call will be terminated.
If you remain out of range for a long time, you may need to re-establish the DECT connection manually when you
return (e.g., by docking the headset to the base).
7.6 NOISE BLACKOUT™ MICROPHONE Jabra PRO 9470
The Jabra PRO midi headset features an advanced, two-microphone Noise Blackout™ system that will help ensure
that your voice will be clear and easy to understand — even when you are sitting in a crowded office or other
noisy environment. It works by using a pair of directional microphones: one facing towards your mouth and one
facing away. These two signals are combined inside the headset, which subtracts the room-noise signal from the
voice signal, leaving only your voice behind.
This system works best when the headset’s voice microphone is placed as close as possible to your mouth and when
the out-facing microphone is completely unblocked. Avoid covering the out-facing microphone with your hand or any
other substance. (Some users assume that blocking the out-facing microphone will reduce noise, but the opposite is true!)
7.7 NOISECANCELLING MICROPHONE Jabra PRO 9460, Jabra PRO 9460 DUO
AND Jabra PRO 9465 DUO
The Jabra PRO 9460, Jabra PRO 9460 Duo and Jabra PRO 9465 Duo feature electronic noise cancelling, which will
help reduce the noise transmitted by your headset, making your voice easier to hear and understand. For best
results, always make sure to place the microphone as close to your mouth as possible.
