Battery condition Indicator: After battery is
installed, turn the power on. The battery
condition indicator signal light should flash
once. If it does not, the battery is installed
incorrectly or it is dead. If the indicator
signal light stays on (does not flash), the
battery voltage is low and the battery
should be replaced. If this happens during
use, replace (or recharge) the battery
immediately to ensure continued operation.
