The circuit will inform you in two ways. |

1.When the PTT switch is pressed and the TX LED blinks. It means the battery level is already Iow and needs recharging. You can still transmit, however, you must finish the conversation and have your battery charged fully to resume normal operation.
2.When the Blinking TX LED went unnoticed and the Battery goes down to where normal communication can no longer be supported, the circuit will disable the PTT switch and emit an error tone every time you try to transmit. Have the battery pack charged fully.
