Abstract
A single indicator lamp is provided on a personal or portable, battery powered radio transmitter to indicate when the transmitter is operated. The lamp is connected to a circuit which senses the battery voltage (and hence charge), which causes the lamp to be energized constantly if the battery voltage is high, and which causes the lamp to be energized intermittently at a rate which decreases as the battery voltage decreases.
