Low Battery Level Detection
Uniden Sundowner UH-oS3 has a built-in
battery level detector circuit. It evaluates your Battery Pack everytime you transmit to determine whether the power inside the Battery is still sufficient enough to support normal
Receive and Transmit communications.
When the PTT switch is pressed and the TX LED blinks. It means the battery level is already Iow and needs recharging. Under this condition, the unit no longer transmits RF Power. Have your battery charged fully or replaced by a fully charged battery to resume normal operation.
