If you turn on the mic and the light is "Green" then the battery is good!

No need to go any further.

If you don't get a green light if it is RED or no light at all the battery needs to be replaced.

Look at the front you should see a battery icon

If you see the icon with 1 line or less replace the battery.


If it has two lines it'll be okay.
