The LED on the front of the transmitter indicates the condition of the batteries. It will flash green during operation if the battery power is sufficient, and will flash red if the battery power is low. If the LED is flashing red, or if the operation becomes erratic, or will only work from a short distance, replace bothbatteries with new AA alkaline batteries.
