Abstract:
A battery powered transmitter is provided with a battery status circuit that determines an output voltage level associated with the battery. The battery status circuit is provided with multiple voltage reference thresholds. One or more visual voltage status indicators are electrically coupled with the battery status circuit. The battery status circuit actuates a visual voltage status indicator when the battery status circuit determines the voltage output level of the battery to be within a first output range. One or more additional visual voltage status indicators may be actuated when the battery status circuit determines the voltage output level of the battery to be within other output ranges.
