Sending RF signals from the Transmitter
The transmitter starts sending the RF signals
automatically, when it detects audio signals from
the equipment connected.
If it does not detect an audio signal for more than
approximately 10 minutes, the transmitter will
stop sending RF signals, and the power indicator
turns off.
When the transmitter receives an audio signal
again, it starts sending the RF signals, and the
power indicator will light in red again.
If the audio signal is very weak, the transmitter
does not send RF signals. If the transmitter is
connected to a headphone jack, make sure the
volume of the equipment connected is set to 5 – 6
or higher.
You may not hear the beginning of the sound
from the headphones until the transmitter starts
sending the RF signals after detecting an audio
signal.
Note
If the transmitter is connected to the headphones jack of
the source equipment, set the volume of that equipment
as high as possible without distorting the audio signal.
The headphones automatically turn
off when they are taken off

After listening to a program

otherwise, the self adjusting band will be pulled up and
