Adjust The Microphone Gain; Test The Microphone - Cisco 8841 User Manual

Adjust the Microphone Gain

You can adjust the microphone gain for the handset, handsfree, and the analog headsets, but
not the headsets that use 3.5-mm jack or the USB ports. You make the gain louder or softer to
get a good input level.
You can change the microphone gain while you are on a call. If you save the settings during the
call, the change is immediate and is used on subsequent calls. If you don't save the settings
during the call, the change is only used for the current call.
1. From your desk phone, press the Applications button
2. Select User preferences > Audio preferences > Microphone gain.
3. Press >> to make the gain level louder and press << to make it softer. The
available options are: Softest, Softer, Soft, Default, Loud, Louder, Loudest.
You can also set the microphone gain based on the device that you use most frequently. Use
either method:
•
Preferred audio device: Set the preferred audio device to what you use most
frequently. For example, if you use analog headset most frequently, then set
your preferred device as Headset from the phone menu User preferences >
Audio preferences > Preferred audio device. Then adjust the microphone gain
of the analog headset, listen to the effect. Then save the one you like. If you
use handset most frequently, pick up the handset, ensure you cancel the
incoming call. Then adjust the microphone gain.
•
Last used audio device: Set the preferred audio device to None from the
phone menu User preferences > Audio preferences > Preferred audio device.
Then toggle the audio path once. For example, press the microphone of the
handsfree on or off once. Then when you adjust the microphone gain, the
microphone of the handsfree will be used for the gain adjustment.
Press Save to save the setting.
