2. Connect the USB mini plug end of the adapter to the USB mini jack located
on the back of the VLC 302.
NOTE: The charger can also be powered by a USB source using a mini
USB cable.
3. If required, unscrew and remove the microphone battery cover to install the
battery. Insert the battery, aligning the + and – poles as indicated inside the
compartment.
CAUTION: Do not replace the batteries with an incorrect type. Use
only rechargeable batteries specified or provided by Extron, or alkaline
batteries.
ATTENTION:
• Do not attempt to charge alkaline batteries.
