 Troubleshooting the Polycom CX300 Phone

 11

• The party I am calling cannot hear me.

Check the following:
— Your phone's microphone is on Mute (the Mute button backlight is lit 

up). 

— The microphone, which is located on the lower-right corner of the 

phone, is pointed toward you and not blocked by other objects. 

— The microphone setting in Microsoft Office Communicator is set 

appropriately. To check, go to Tools in Microsoft Office 

Communicator, select Set Up Audio and Video, select the Polycom 

CX300 phone from the applicable drop-down menus, and then adjust 

the volume settings.

— The speaker and microphone volume settings in the computer’s 

Windows operating system may be turned too low or to No Sound. To 

check, locate the appropriate Sounds application in the Windows 

Control Panel. Remember that any changes in sound levels that you 

make in your operating system will be reflected in all the phone’s 

audio devices. Also, although you can change volume playback and 

recording levels of your phone by using the Sound application in 

Control Panel, it is not recommended. 

• The party I am calling can hear noise.

Check the following:
— Your phone is pointed toward you and is not blocked by other objects.
— Make sure that the microphone is pointed toward you and turned 

away from the source of the sound.

Check the following:

• The volume level of the speaker of the phone device that you are using 

(handset, headset, or speaker) may be set too low. Raise the volume level 

by pressing the Playback volume + button on the keypad. Be aware that 

the volume settings of the handset, headset, and speaker are independent 

of one another. Changing the volume setting of one device does not 

change the volume setting of the other two devices.
