Reason for Advisory:

Microphone LED behavior is incorrect if system is downgraded from CE8.0.0 to TC software.
CDETS No: CSCux85199

Headline:

Microphone mute button does not work as expected and mute LED glows red constantly when

the microphone is not muted.

Description:

Expected behaviour: The mute LED should glow green while the SX20 is in standby and un-

muted. When the microphone mute button is pressed it should change to red (muted). The LED

should never be turned off.
Problem: After upgrading to CE8.0.0 and then downgrading to TC software the mute button on

the microphone glows red constantly when the system is un-muted. When the system is muted

the LED light is turned off, when un-muted again it will glow red. When pressing the mute

button on the microphone it self nothing happens.
Problem Symptoms:
1. Nothing happens when you press the button on the microphone.
2. The LED of the Touch (if connected) and mic on/off indicator on the screen is not aligned.

(Touch mute LED is green, microphone mute LED is red)

3.  When the MIC is muted, the microphone LED is turned off (using web interface or CLI).
4.  When the MIC is un-muted, the microphone LED is RED.
5.  The microphone LED will never be green.
