THE LED INDICATOR (LIGHT) ON THE DOPPLER IS BLINKING, WHAT DOES IT MEAN?
When the battery is running low, the light will begin by flashing slowly. At this point you can still use the doppler for some time. As the battery becomes too low, the light begins blinking more rapidly and will eventually shut the doppler off. The doppler unit requires regular 9 volt batteries that can easily be replaced by removing the small panel in the back of the doppler.
