Lennox Hearth 9470 user manual Staying within Range, Noise Blackout Microphone Jabra PRO

8.Align the wired connector for your new battery with the socket inside the headset and press it all the way in. If you have trouble, you might have the connector upside down — try the other way.

9.Fold the wires beside the new battery in the wire groove and press the battery down into place in the headset. Ensure that the battery label faces upwards for the correct orientation.

10.Replace the speaker plate and insert and tighten each of the three screws you removed at the start of this procedure.

7.5Staying 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.

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, all sound will stop 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).

7.6Noise 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!)

7.7Noise-Cancelling Microphone (Jabra PRO 9460 and 9460-Duo)

The Jabra PRO 9460 and 9460-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 moth as possible.
