You should now be able to walk freely from room to room enjoying full
stereo sound. If you notice interference (noisy signal or if the sound is
distorted or breaks up), adjust the frequency by turning the thumb
wheel control located on the front of the transmitter base either left or
right. Then, push the "Auto Scan" button on the headphone to lock into
the new frequency. This should help you to obtain better reception with
the headphones. You may have to try this adjustment several times to
obtain optimum performance, depending on the conditions. Please refer
to the following drawings A and B for best tuning:
Keep a distance of about 20 feet between the headphone and the
transmitter when adjusting the tuning knob for best stereo reception.
Whenever you find interference, readjust the frequency of the
transmitter by turning the thumb wheel and then pushing the
"Auto Scan" button on the headphone to lock in a new frequency.
For protection of the transmitter and to save power, the transmitter
will cut off automatically after about one minute when the input
signal from an audio source is too weak for operation. If the signal
from the audio source returns at a sufficient level, the transmitter will
turn on again automatically.
