How do I change the batteries?
BATTERIES INSTALLED
Simply slide the battery door to the right. Remove

two left batteries. The screen to the left will
appear. This screen will help you orient the new
batteries. Replace with four fresh AA alkaline bat-

the two left most batteries first, then the right ones.
