Printed in the USA

You need two AAA batteries (not supplied) to
power your microphone. We recommend al-
kaline batteries, such as RadioShack Cat.
No. 23-555. To install the batteries, slide
them into the battery holder on the bottom of
the microphone stand, according to the po-
larity shown in the holder. 

After you install the batteries, plug the micro-
phone’s cable into your computer’s sound
board.
