6. OPERATING THE HEADPHONES
The aircraft must be powered up before the headphones will function. Set the volume control of
the headphones to minimum. Press the power button on the headphones. Once the headphones
detect a signal, the LED indicator on the headphones will turn green and the transmitter will
transmit the audio signal. If no signal is detected, the LED indicator will be red.
Turn on the headphones and slowly increase the volume, using the volume control on the
headphones to adjust the volume to the desired level.
Switch between the audio sources using the small channel select switch on the headphones. How
the transmitter is installed determines what sources are available.
After each use, be sure to switch off the headphones to extend battery life.
When the headphones detect no signal for more than one minute, the headphones will power off
and the LED indicator will go out. Reactivate the headphones by pressing the power button.
