When the batteries near the end of their useful life, the battery indicator will flash. 
To change the batteries, depress the release tab using a coin or screwdriver and 
slide the cover back. Replace the batteries with two new “D” cell alkaline batteries. 
Replace the cover by holding it in place along the side rails while sliding it forward 
to engage both the rear hooks and the front release tab.
To avoid accidental damage to Whisper or the headphones, unplug the 
headphones when placing it in the case for storage.
