Uniden UH-O53 - Manual (Page 10)

Low Battery Level Detection
Uniden Sundowner UH-053 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
low 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.

The UH-053 is designed to give you trouble-free
service. There are no user-serviceable parts
