improved.
3. Press the Auto Tune button
again to improve the quality
still further.
NOTE: The Transmitter will turn
off automatically about 5 minutes if there is no audio signal
from the audio source (TV set, etc.), or the signal from the
audio source is too weak for proper reception. However, if the
audio signal returns to an acceptable level, the transmission
will automatically restart.
