remains on whenever the unit is powered on . The LED will illuminate in one of three
colors to indicate the battery voltage level .
if the leD is green, the batteries are fully charged or have sufficient voltage for
normal operation .
if the leD is orange, the batteries have enough voltage to operate, but should be
recharged when the current usage of the unit is complete .
if the leD is red, the batteries should be immediately recharged to prevent erratic
performance and / or failure of the unit during operation .
