If the RED LED light on the radio is dark, dim, or blinking during transmission, what does it indicate?

The indication that the RED LED light on the radio is dark, dim, or blinking during transmission signifies that the radio battery is low and requires charging. When a radio's LED light behaves in this manner, it is a critical alert for the user to take action regarding the power source of the device. A properly functioning radio should have a steady and bright RED light during use, indicating it is operating normally and has adequate power.

Recognizing a low battery condition is essential because functioning equipment is vital for effective communication, especially in transit environments where safety and coordination are paramount. Charging or replacing the battery ensures that the radio remains operational and dependable for ongoing use.
