Microphone Not Picking up Sound
Problem
You cannot be heard when using your headset.
Solutions
Check to make sure your microphone is not muted. Press the mute button on your headset to mute and
unmute your microphone.
Make sure that the microphone boom has been lowered. For optimal sound, keep the headset microphone
no further than 1 in or 2.5 cm from your face.
Make sure that your headset is properly plugged into your device.
For the Cisco Headset 560 Series, check that you are not taking your headset too far from the headset
base. The headset has an effective range of approximately 100 feet or 30 meters.
Headset Not Charging
Problem
Your Cisco Headset 561 and 562 is not charging when placed on the base.
Solution
Check that your base is plugged into a reliable power source.
Make sure that your headset is properly seated on the base. When the headset is properly seated, the LED
shows solid white. When charging, the LEDs on the base light up in sequence from left to right. When
the headset is fully charged, all five battery indicator LEDs show solid white.
